We arrived at Vitamin D as COVID-19 cure

It was only logical that COVID-19 will be cured with vitamin supplements. Peer-reviewed science is now catching up with the bustling Vitamin D market.

It had to happen. Vitamin supplements are promoted for every malaise, and COVID-19 is the hottest business opportunity one can get. After the initial confusion with stem cells, nanotechnology, hormones, irradiation, and of course chloroquine and its derivative hydroxychloroquine (HCQ), the world came to its senses and recognised that only a prescription-free drug can cure COVID-19, otherwise where is the fun in that.

Since most COVID-19 victims are senior citizens, anti-aging companies arrived on the spot offering their proprietary supplements as COVID-19 prevention or even therapeutic medicine. While these fancy NAD+ and resveratrol supplements sound cool and futuristic (anti-aging!) it excludes other hard-working scammer and grifters who also wish to sell something but have patented nothing. The mineral supplement Zinc is literally dirt cheap and thus has a potential, since it was prophesied by quack-messiah Vovka “Zev” Zelenko of New York as important ingredient in the HCQ cure, but then again, you still need prescription drugs HCQ and the antibiotic azithromycin for Zinc to do its magic on COVID-19. A vitamin would be perfect, pensioners always need those, vitamins are always good, the word alone is reassuring. But which vitamin?

While scratching their bottoms about whether to go for Vitamin A, Vitamin B or Vitamin C (which cures all diseases anyway, cf Nobel Prize winner Linus Pauling), with some Dutch merchants peddling Vitamin K, and surely Vitamin E is an option, too, the experts seem to have eventually arrived at Vitamin D. Why?

Well, as the coronavirus is raging uncontrolled in the United States because the President Donald Trump does not like bad news, most deaths happened among the Black and LatinX communities. Which is for sure not something making the Imperial Wizard Trump sad, but it made some biomedical scientists think. What if it is not the poverty, failed public health and blatant institutional racism which kills Black Americans in the pandemic, but something as simple and cheap as a lack of Vitamin D? In humans, the vitamin is naturally produced by exposure to sunlight, of which white skins takes up more than dark skin, so you see where this is going.

If you need scientific guidance, genetics professor Ewan Birney, director of EMBL-EBI in Edinburgh, can explain. Even a Time article highly critical of the Vitamin D theory of COVID-19 medicine wrote this:

“Indeed, many of the known risk factors for COVID-19—being Black or Hispanic; being elderly; having an underlying health condition; having a high body mass index—are also risk factors for vitamin-D deficiency.”

You see, since LatinX people are not perfectly pale white, they count as Vitamin-D deficient also, even if they live in the polar regions of California. In fact, US insurances might register being non-white as pre-existing medical condition (yes, I am aware they are eager to do exactly this as Trump dismantles Obama’s Affordable Care Act). Even The Lancet chimed in with some race medicine, via a comment article by British experts Adrian Martineau and Nita Forouhi endorsing Vitamin D supplements:

“The striking overlap between risk factors for severe COVID-19 and vitamin D deficiency, including obesity, older age, and Black or Asian ethnic origin, has led some researchers to hypothesise that vitamin D supplementation could hold promise as a preventive or therapeutic agent for COVID-19.”

Yes, we forgot Asians! Which explains such horrendous rates of COVID-19 in India, it must be the dark skin, and the lack of sun because unlike COVID-19 resistant British folks, those Indian farmers are always indoors…, ah crap, never mind. Since when are non-peer reviewed reality facts allowed to interfere with peer-reviewed science?

Vitamin D theory of COVID-19 is beautiful. It allows you to roll out any crypto-racist bunk and pretend it’s solid science, while peddling prescription-free supplements out the back. And in America, they love racial medicine, US hospital algorithms distribute (or rather deny) healthcare according to your skin colour, which bottom line is that Black people are more primitive than whites and therefore need less medical care.

Studies correlating COVID-19 to Vitamin D levels arrived quickly as the pandemic grew, and now gain traction as the HCQ hype declines. This paper from 3 September is probably the most headline-grabbing one, because it is from USA and appeared in JAMA. No wait, it’s the downstream Open Access cash-making outlet, JAMA Network Open, where it costs $3000 to publish.

David O. Meltzer, Thomas J. Best, Hui Zhang, Tamara Vokes, Vineet Arora, Julian Solway Association of Vitamin D Status and Other Clinical Characteristics With COVID-19 Test Results JAMA Network Open (2020) doi: 10.1001/jamanetworkopen.2020.19722 

The authors accessed health records of COVID-19 patients and concluded that those who eventually caught the virus had low Vitamin D levels before:

In this cohort study of 489 patients who had a vitamin D level measured in the year before COVID-19 testing, the relative risk of testing positive for COVID-19 was 1.77 times greater for patients with likely deficient vitamin D status compared with patients with likely sufficient vitamin D status, a difference that was statistically significant.

Yes, the skin colour of patients was noted. None of the participants was actually Vitamin D deficient, so the authors set some threshold to assign them as “likely deficient”. They did notice that many had various pre-existing conditions like obesity, diabetes or cardiovascular problems, all COVID-19 risk factors. Low Vitamin D levels used to be see in the pre-COVID-19 times just an general biomarker of bad health, but now they became the main cause for getting infected with COVID-19 in the first place. Maybe confused by the fact that the majority of their analysed patients were not white, the authors conclude:

Since African American and Hispanic populations in the US have both high rates of vitamin D deficiency and bear a disproportionate burden of morbidity and mortality from COVID-19,35,36 they may be particularly important populations to engage in studies of whether vitamin D can reduce the incidence and burden of COVID-19.

What a lovely idea. Instead of providing public health and insurance available to everyone, why not telling Black and Hispanic Americans to pop some cheap Vitamin D pills.

As paediatrics professor Todd Alexander of University of Alberta was quoted in Folio, this Vitamin D deficiency and weakened immunity theory is not new, and has been used to explain diseases before:

“In the 1980s and ’90s, studies emerged that found a role for vitamin D in immune function. This, according to Alexander, led to a deluge of clinical studies finding reduced vitamin D levels in people affected by a host of diseases including asthma, cancer, diabetes and multiple sclerosis.”

Those cancer and asthma studies are now long forgotten, except by some unscrupulous vitamin peddlers. Correlation is not causation, but unfortunately not every scientist will agree with Alexander. Aside of rickets (which is a real Vitamin D deficiency syndrome) medical science has so far failed to convincingly connect any other disease to Vitamin D deficiency. Thanks to modern diet, there are anyway only few people with critically low Vitamin D levels in need of supplementation, while these unnecessary supplements do increase calcium uptake up to the formation of kidney stones. Doctors already noticed cases of Vitamin D poisoning in COVID-19 risk group patients who tried to “boost immunity”.

But then again, there is COVID-19 pandemic going on and their is no time for the scientific method.

The market for Vitamin D was already there, which is another beauty of the approach. Because everyone was convinced that showing yourself outside unprotected will immediately give you skin cancer, a notion supported by the extremely successful sunscreen industry (even thoughmelanoma rates in the U.S. have tripled since the 1970s, even as the use of sunscreen has increased“), there evolved a need to counteract the sun avoidance and the resulting potential Vitamin D deficiency with supplements. And now there is COVID-19 on, and what coincidence, Vitamin D helps also against that! The science has spoken.

Especially since the Vitamin D approach is such great business and also great fun. How about European COVID-19 death rates explained with dark-skinned Italians and lazy Spaniards doing their siesta in the shadows while the Nordic races toil in the fields, with their proud white faces turned towards the sun? Here is a paper from the (apparently COVID-19-resistant) UK on just that, its p-values for Vitamin D levels vs COVID-19 cases and mortality just happen to be exactly p=0.05, the magic value.

Petre Cristian Ilie, Simina Stefanescu & Lee Smith The role of vitamin D in the prevention of coronavirus disease 2019 infection and mortality Aging Clinical and Experimental Research (2020) doi: 10.1007/s40520-020-01570-8

The Southern European countries have lower levels of vitamin D because of decreased exposure (prefer the shade in strong sun) [10] and also as skin pigmentation decreases vitamin D synthesis [11]. Northern part of Europe’s mean levels are better as a consequence of the consumption of cod liver oil and vitamin D supplements as well as fortification of milk and milk products (Finland) [6].”

Indeed, it must be all that Surströmming which Swedes eat, if anything it ensures social distancing. You might wonder who takes such a braindead and bigoted study seriously. Professor Helmut Schatz does, one of Germany’s top endocrinologists. Former governmental advisor Professor Hans-Konrad Biesalski of University of Hohenheim in Stuttgart analysed 30 studies, including the coronavirus effects on the “black race“, and urged Germans in June 2020 to take Vitamin D supplements for COVID-19. Elsewhere in Germany, the ultra-right xenophobes and rabid COVIDIOTS of the Alternative für Deutschland (AfD) demanded, also in June 2020 that the German Bundestag issues Vitamin D recommendation for COVID-19 prevention. Their proposal was rejected.

Vitamin D from fish is what keeps Sweden COVID-19 free!

But also Italians and Spaniards themselves are jumping the bandwagon. Endocrinologist Luigi Gennari of University of Sienna presented his research to a closed circle at a conference, and nobody else, which should suffice. He concluded:

Our data give strong observational support to previous suggestions that reduced vitamin D levels may favor the appearance of severe respiratory dysfunction and increase the mortality risk in patients affected with COVID-19“.

And in Spain, just look at this clinical trial from Cordoba, which used the Vitamin D analogue calcifediol. It cannot be more convincing:

Marta Entrenas Castillo, Luis Manuel Entrenas Costa, José Manuel Vaquero Barrios, Juan Francisco Alcalá Díaz, José López Miranda, Roger Bouillon, José Manuel Quesada Gomez “Effect of Calcifediol Treatment and best Available Therapy versus best Available Therapy on Intensive Care Unit Admission and Mortality Among Patients Hospitalized for COVID-19: A Pilot Randomized Clinical study” The Journal of steroid biochemistry and molecular biology (2020) doi: 10.1016/j.jsbmb.2020.105751 

Only 2% of the 50 Vitamin D treated patients went to ICU as opposed to 50% of 26 patients who did not get Vitamin D!

Now, I really must commend the authors for their cleverness. The clinical trial started by dosing all COVID-19 patients with HCQ, but then that chloroquine cargo cult ship has sailed, or rather ran aground (its unhinged captain Didier Raoult crying sabotage as Marseille went from HCQ religion hotspot to COVID-19 hotspot). Hence the clever Cordoba investigators quickly switched to a new magic drug, Vitamin D, on top of HCQ! The journal they chose is not really specialising on clinical trials (aside of reviews), but it does specialise on Vitamin D research. Which was good enough to find the right reviewers. Who agreed with the authors that the many COVID-19 deaths Spain has experienced are due to Spaniards not getting enough sun in the winter.

Update 17.11.2020. The Castillo et al paper seems to be extremely authoritative, maybe because not many bothered to read it properly, but here is a nice takedown by DW Science. It quotes Martin Smollich, pharmacology professor at University of Lübeck in Germany, who noticed that the placebo control arm of the clinical trial included 19% of diabetics and 57% of hypertension sufferers, who are the highest COVID-19 risk group. The Vitamin D arm, where the survival rates were so much higher, happened to have merely 6% of diabetics and 24% of hypertension patients. But it passed peer review, so how dares Smollich to criticise it now!

Now, we arrive at some really serious money making. With these authors it cannot be any more obvious that they are all unashamed Vitamin D industry shills. Especially the last character on that paper.

Harvey W. Kaufman, Justin K. Niles, Martin H. Kroll, Caixia Bi, Michael F. Holick SARS-CoV-2 positivity rates associated with circulating 25-hydroxyvitamin D levels PloS one (2020) doi: 10.1371/journal.pone.0239252

The first four authors are employees of Quest Diagnostics, which tests your blood Vitamin D levels and then sells you Vitamin D supplements. The last author is the notorious Michael Holick, described by New Yorker as “The Child-Abuse Contrarian”, who issues bizarre medical diagnoses over the phone and whose custom-curated promotional Wikipedia profile was eventually vandalised by the reality. A Controversies section was added:

Holick has been involved in several medical controversies. While at Boston University, he was asked to leave the Division of Dermatology because of his promoting the medical benefits of sun exposure. He accepted research funding for this work from a non-profit tanning bed company, considered by many to be an important potential bias. Barbara Gilchrest, then head of the department at Boston University, called Holick’s book “shlock science” and Holick “a poster boy for the tanning industry”.[50]

Holick received nearly $163,000 from 2013 to 2017 from pharmaceutical companies, according to Medicare’s Open Payments database, which tracks payments from drug and device manufacturers. The companies paying him included Sanofi-Aventis, which markets vitamin D supplements; Shire, which makes drugs for hormonal disorders that are given with vitamin D; Amgen, which makes an osteoporosis treatment; and Roche Diagnostics and Quidel Corp., which both make vitamin D tests.[51]

Holick has also been criticized by other physicians because of his testimony, defending accused child abusers by asserting that Ehlers-Danlos Syndrome is a cause of non-traumatic fractures in infancy (rather than abuse).[52] Experts in Ehlers-Danlos syndrome, as well as pediatricians specializing in traumatic bone injury, refute Holick’s position, which is completely unsubstantiated by the medical literature. In over 300 criminal cases Holick has never concluded that the child who suffered broken bones had been abused. In one case of a child who had suffered broken bones in which Holick defended the accused parent, the child later went on to suffer severe brain injury, for which the parent has been indicted.[53]

Since May 2017, Holick has been barred from evaluating or treating children by Boston Medical Center, which subsequently reported him to the Massachusetts Board of Registration in Medicine for “health care facility discipline.” [54]

In January 2018, Robert Marvin Ray, one of the parents whom Holick worked with over child abuse suspicions, was arrested and charged with child abuse.[50][55]

His promotion of Vitamin D has been called extreme, even speculating that the extinction of dinosaurs caused by a lack of it in reduced sunlight.[56]

Would you as a journal editor accept anything from such a “scientist”? Well, PLOS One did. Maybe they were impressed by the sheer numbers of patients:

This study used a retrospective, observational analysis of deidentified tests performed at a national clinical laboratory to determine if circulating 25-hydroxyvitamin D (25(OH)D) levels are associated with severe acute respiratory disease coronavirus 2 (SARS-CoV-2) positivity rates. Over 190,000 patients from all 50 states with SARS-CoV-2 results performed mid-March through mid-June, 2020 and matching 25(OH)D results from the preceding 12 months were included.

Over One Hundred Ninety Thousands of patients, who can say no to such a gigantic clinical trial dataset, especially if it promises The Cure for COVID-19? If it reminds you of the Surgisphere scandal for which both The Lancet and NEJM fell arse over tit, well, this is how scholarly publishing works. The story counts, not the author’s or their dataset’s credibility.

Holick’s Boston University of course proudly issued a press release. But PLOS One might have second thoughts:

Having tweeted their concern on 24 September, the next day PLOS One published yet another paper by Holick about curing COVID-19 with Vitamin D. It first appeared as preprint on the Elsevier’s SSRN server, which is a much fancier preprint server than others because it is named “Preprints with THE LANCET“. Now in PLOS One, what honour for the journal.

Zhila Maghbooli, Mohammad Ali Sahraian, Mehdi Ebrahimi, Marzieh Pazoki, Samira Kafan, Hedieh Moradi Tabriz, Azar Hadadi, Mahnaz Montazeri, Mehrad Nasiri, Arash Shirvani, Michael F. Holick Vitamin D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with COVID-19 infection PLoS ONE (2020) doi: 10.1371/journal.pone.0239799

This time, the authors saved “only” 235 patients in Iran, while PLOS One informs you: “The authors have declared that no competing interests exist“. Not even Holick, half of whose business is Vitamin D grifting (the other half being helping child abusers in court).

But now, the best Vitamin D for COVID-19 paper ever. Straight from the French Parliament, Assemblée National, and its MP, Joachim Son-Forget. This professional politician once studied medicine and did a PhD in psychology, which automatically made him expert for many things sciency, these days always ready with an educated and even peer-reviewed guess about COVID-19. Son-Forget has been promoting HCQ on Twitter and he of course is a great admirer of the greatest French scientist of all times, Didier Raoult (for whom he even raised money, it seems).

A great scientific mind himself, Son-Forget (and colleagues) postulated in Medical Hypotheses, a comedy magazine run by Elsevier, “that betathalassemic heterozygote population prevalence is correlated to immunity against COVID-19, by a regression“. Would you like to see the data they based this assumption on?

The polymath knowledge of Dr Son-Forget, MP is evident in his genius way of plotting that regression.

Incidentally, the authors list there was exactly same as on this stroke of genius, this time about the Vitamin D:

Édouard Lansiaux, Philippe P. Pébaÿ, Jean-Laurent Picard, Joachim Son-Forget Covid-19 And Vit-D: Disease Mortality Negatively Correlates With Sunlight Exposure Spatial and Spatio-temporal Epidemiology (2020) doi: 10.1016/j.sste.2020.100362

The authors (or rather only Edouard Lansiaux who has to vouch for everything) analysed COVID-19 related health data from France, except colonies and Corsica because the authors decided they have much sun but not enough hospitals there. They concluded:

in continental metropolitan France, average annual sunlight hours are significantly (for a p-value of 1.532 × 10−32) correlated to the COVID-19 mortality rate, with a Pearson coefficient of -0.636. This correlation hints at a protective effect of sunlight exposure against COVID-19 mortality.

And indeed, there is no COVID-19 at all in Marseille, famous for its radiant sun (who is of course Didier Raoult). Don’t believe the news.

A Letter to Editor regarding that article by Son-Forget was published in the same journal, its authors are Florian Naudet, Clara Locher, Alain Braillon and André Gillibert. They listed “Major statistical flaws”in Son-Forget’s research and concluded:

the manuscript has no informative value at all concerning any association between “Covid-19 And Vit-D”. Therefore, we think that the article methods and conclusions are too flawed to have any value.

But, as scholarly authorities advice, we must remain open regarding Vitamin D as COVID-19 medicine. Especially since the former CDC director Tom Frieden advised Americans already in March 2020 to take Vitamin D supplements for COVID-19 prevention.

The Vitamin D hype is working. Even Anthony Fauci himself recently advocated the supplement:

If you are deficient in vitamin D, that does have an impact on your susceptibility to infection. So I would not mind recommending, and I do it myself taking vitamin D supplements“.

The 78 year old Fauci also recommended taking Vitamin C:

that vitamin C is “a good antioxidant.” “So if people want to take a gram or two at the most [of] vitamin C, that would be fine

Sure, people in Fauci’s age are in danger of vitamin deficiency and some might need supplements to support their weakened immune system. But old age is about much more than maybe lacking some Vitamin D, so the causality with COVID-19 severity is very strenuous there at best. Maybe it all is Fauci’s diplomatic way for distracting Americans from taking HCQ. Or drinking bleach.

And anyway, the only real prevention cure for COVID-19 is cabbage.

Update 15.12.2020

Of all Vitamin D papers out there, this one by marketing professor Bernd Skiera from my neighbourhood Goethe University Frankfurt takes the proverbial biscuit.

Rahul Kalippurayil Moozhipurath, Lennart Kraft & Bernd Skiera, Evidence of protective role of Ultraviolet-B (UVB) radiation in reducing COVID-19 deaths. Scientific Reports (2020). doi: 10.1038/s41598-020-74825-z

Brief summary:

  • COVID-19 deaths are caused by Vitamin D deficiency, science fact
  • UV light is great
  • But UV light is also bad, in can cause cancer
  • Solution: buy Vitamin D supplements, a preventive and therapy for COVID-19!

Now read this Conflict of Interest disclaimer:

RKM is a PhD student at Goethe University, Frankfurt. He also is a full-time employee of a multinational chemical company involved in vitamin D business and holds the shares of the company. This study is intended to contribute to the ongoing COVID-19 crisis and is not sponsored by his company. BS also holds shares of the company.”

The company is BASF, Rahul KM does consulting for it. BS does not stand for bullshit, but for Professor Bernd Skiera, The Teutonic Genius Who Saved The World from COVID-19.

Update 28.12.2020

Now it gets serious, the IT folks are the to solve Covid-19!

The Open Letter from 7 December 2020, organised by the former Google exec and now anti-aging biotech investor Karl Pfleger , IT entrepreneur Gareth Davies and some others, is signed by currently 150 doctors, academics and British politicians (all disclose their own daily Vitamin D supplement uptake). It declares:

“Vitamin D is much safer than steroids, such as dexamethasone, the most widely accepted treatment to have also demonstrated a large COVID-19 benefit. Vitamin D’s safety is more like that of face masks.”

The list of signatories includes shills like Holick, but also other names I recognise: the Twitter celebrity doctor Eric Feigl-Ding, former Brexit negotiator David Davis MP and UCL’s chief eugenics enthusiast Steve Jones.

Oh, and there is also another “Evidence Synthesis” paper from the UK:

George Griffin, Martin Hewison, Julian Hopkin, Rose Kenny , Richard Quinton, Jonathan Rhodes, Sreedhar Subramanian and David Thickett Vitamin D and COVID-19: evidence and recommendations for supplementation Royal Society Open Science (2020) doi: 10.1098/rsos.201912

We learn that people with dark skin are low in Vitamin D and hence die of COVID-19 more often. While look, Italians and Spaniards don’t get enough sunlight:

Figure published by same authors previously in May, Laird et al 2020, hence the European mortality ratios a bit outdated, but who cares.

The paper concludes:

“There seems nothing to lose and potentially much to gain by recommending vitamin D supplementation for all, e.g. at 800–1000 IU/day,”

Two authors (including Thickett) declared to receive speaking honoraria from Vitamin D seller Thornton Ross.


If you are interested to support my work, you can leave here a small tip of $5. Or several of small tips, just increase the amount as you like (2x=€10; 5x=€25). Instead of buying Vitamin D supplements?

  1. Why did we evolve white skin then? Surely it’s an evolutionary benefit – we generate Vitamin D and then die less often of infections.


    • I couldn’t get through this artcle. The writer’s supposed goal of elucidating the science is contorted to his principal goal of proclaiming racism and spewing poison at everyone reporting their understanding of the medical findings.

      I don’t mind a generalized hit piece, but let him give the facts straight and save the snideness for a criticism after reporting the claims and then his political blame fest would be more acceptable.

      BTW I thought that Obamacare is still the law and that that was the generalized solution to all the deprivation claims he posits!

  4. Maybe you overdid it, because 20K IU daily of D is a lot, like as in likely WAY too much based on anything I’ve ever read on the subject. I’ve read ONLY that 10K IU daily is an absolute upper limit before experiencing some nasty side effects like kidney failure. Otherwise, in general (though not specifically), I’ve read that 4K is a safe upper limit. The other thing is, did you ever get a vitamin D blood serum test to see what your D level was at before pounding down 20K IU a day? Or did you just start taking vitamin D after COVID was already a pandemic? I’ve personally been ingesting 3K to 4K IU daily for well over 20 years, so there’s no question that I was never running a deficit at the onset of the virus. But I did have a serum blood test done just a few months ago and my level was at 40 nanograms to the milliliter, which is actually optimal without being too much. Levels of 60 and over are often toxic, so be mindful about what you’re doing to yourself…☝️


    • Tom Connelly

      I guess that you aren’t familiar with how K2 works with Vit D? How K2 (not K1) prevents the calcium issues completely? There’s also an MD with an ebook out about he and his entire practice is taking 30K IU daily for years with no issues, and that is without considering K2. But, K2 and magnesium are your answers to “Vitamin D toxicity”… Look into it and you’ll find the answers. Problem is, most people can’t get enough K2 without supplements unless they like Japanese natto, which thankfully I love the stuff. Highest food source. (K2, not K1) …and specifically the MK-7 type of K2, which has a much higher half-life in the body. Vitamin D is not and cannot be toxic. That’s a farce. The problem is other deficiencies can happen as a result of high D intake, like magnesium, and without enough K2 then you get the calcium issues. K2 prevents that.

        Excellent and absolutely correct comments- i just have to totally endorse your comments. The problem today is that preconceived and motivated articles are being witten by persons without adequate knowledge and understanding – sad. Vitamin-D really boosts one’s immunity immensely – i have tried it out on myself, my mother – 87, on a host of friends and relatives, all of whom have benefited in various ways – and my informal trials are an ongoing process. I realised this and a lot more during my research after my prostate cancer treatment through radiation and chemotherapy.

  5. I would hazard a deficit in testing on people Not deficient in vita D. I had been taking 20,000 of D qd, and Still contracted Covid19; in fact, I now have Covid19 Syndrome, the moniker applied to long term effects covid. I’m currently at 6.5 Months!! Am I an anomaly? I was fit and healthy as well, but Vita D didn’t spare me from this virus. Maybe, back to the drawing board. Start again. Speculation does not make for good Science.


    • 20,000 what? What was your tested Vit D level before you caught Covid?


    • 20000 of D qd. Are you joking…or are you just plain fibbing. If you mean 20000 IU 4times a day (qd) you are a dead fish.

      • Not a dead fish, the only case studies I can find of Vit D toxicity involved taking 50-60,000 IU/day for months. They stopped and were mostly fine, I think. Still, it’s an absurd and dangerous dosage and Donna’s post is nonsensical not least because at best Vit D might only reduce risk, it won’t eliminate it.


  6. Hello, my theory is that the “capsaicin” in hot chili peppers will kill COVID-19 on contact. I have proven this to my own satisfaction, since I eat a lot of hot peppers every day and I don’t have the virus (yet). I also go to wild parties with no distancing & no masks, and I don’t have the virus (yet). In places where I do have to wear a mask (for cosmetic purposes), I use a toothpick to puncture the rows of little squares on either side of my KN95 masks so that it’s easier to breathe (the virus) in and breathe (the virus) back out. And I still don’t have the virus (yet). So my medical advice is to eat enough hot chili peppers until they burn the hole in your ass and you’ll also be saying — “See there, I don’t have the virus (yet)!”


  7. COVID is actually the cure- the disease is liberalism..
    Take vitamin D or not I could not care less, but for the poor person who might have stumbled into this site and might be convinced it all just a scam, Dr Fouchi is taking 6000iu a day, that’s 10x the recommend dose for his age.

    It might be worth mentioning that vitamin D is a hormone that regulates the immune system and gene expression.

    While you are sadly right about the US administration just letting the people die and the “public health” in US being a cynical joke, those speaking about the vitamin D in Covid are also right.
    I mean, absolutely, really right.
    First, the investigators discovered that most victims had a deficiency of this immunomodulator.
    There was a long scientific voyage after that, and, to my surprise, despite more and more proofs, for many months nobody advocated the vitamin D, neither the politicians, nor the press… not as they are advocating other stupid, unprooved remedies.
    Only recently they started to speak about it, still timidly.
    I don’t mean publishing studies… yes, the doctors and even the public media are doing this. I mean political or medical representatives just going out in public and saying loudly and clearly, in easy to be understood words: “People, do take vitamin D supplements!” (You know, like the orange idiot did about that cleaning substance that killed a lot of illiterate people… only being right, in this case, not dangerously inept.)
    Long story short, recently it was conducted a study in Spain, in which 50 individuals with COVID received calcifediol (the easiest to be absorbed form of vitamin D), and other 26 individuals of similar ages and comorbidities did not received it. From those 50 in the test group only 1 person ended up in hospital with complications, but walked away afterwards on his own, while from those 26 unlucky members of the “control group” 13 persons, a huge 50%, developed bad complications and 2 died.
    I won’t insult you providing sources for what I just wrote above.
    You are the journalist, not I…
    I am sure you will be able to cross-reference this.
    I am just a foreigner living in Spain (no, not an English native, so please forgive my bad English), who’s life happens to have been saved when I caught the bloody virus, but fortunately my family doctor was giving me at that time a rather big monthly dose of calcifediol. Against all odds (I am a high risk patient) I survived, without being even hospitalized. I was bedridden for more than 10 days and suffered a lot but my lugs were perfectly ok. No, my doctor had no idea about the vitamin D in Covid cases, not then… it was only April. He was giving me calcifediol for my usual, huge deficiency of vitamin D and an autoimmune illness. It seems he saved my life 👍
    So, please, do a research about it and don’t scare the people against a perfectly valid scientific breakthrough. They are enough confused and manipulated and scared as it is. IMHO.

      Kama, he actually references that study although it’s mostly a snarky comment about how they were being given HCQ+AZT before “that ship had sailed”. Which is fine, it just dates the start of the study to being at the beginning of the epidemic.

      He references the study. He has done SOME research. There are legitimate questions to be answered, with that study, about how the masking was done – how the study itself was carried out. It’s not clear, from the paper, whether specialists treating the patients had access to patient status regarding whether they took calcefidiol supplement or not. It is also a very small study, just 76 patients.

      He points out that this was published in a journal which specialises in vitamin D which is incorrect, it was published in a journal which specialises in the use of steroids in medicine.

      Your response also is incorrect: all of these patients were admitted to the trial on admission to hospital. All 76 were being hospitalised which meant they already had respiratory failure. It is not that only 1 from the medicated group was admitted to hospital: it is that only 1 from the medicated group was admitted into intensive care (ICU). In the context of Covid-19 that typically means on a ventilator in a medically-induced coma.

      The numbers are pretty stark and if true should encourage the use of calcefidiol when patients first develop symptoms. The author is dismissive of this study and it’s not clear as to why.

    Immune health being impacted by Vitamin D level is well established. To what degree, irrespective, or as a function of race in particular, this is true I don’t know. But obviously, immune health is important in Covid-19 response. We do know that the darker your skin (which is evolution based upon historical need of your race based on geography of origin) – the more UVB is necessary for the same level on conversion – that’s simply science – neither good nor bad, but reality. Accordingly, initially separating this discussion from race is important. Additionally, regardless of race, all races of people on average, test as deficient if they live above latitude 38, from Fall through early Spring – with the only reasonable only option supplements, as it’s well established food alone will not avoid deficiency. Especially at this time given the pandemic – but in general – anything we can do to easily optimize immune health makes sense, i.e. as long as we are assured there’s only upside. In that regard, like adequate sleep, hydration and good nutrition, vitamin D3 supplementing makes sense. Bottom line: there’s been no study that has shown anything but upside to having a 25 hydrxo vitamin D level above 40 ng/ml and below 50 ng/ml – for general health. Note: That level is one-third of the level of toxicity of 150ng/ml – so toxicity doesn’t reasonably seem a risk if people follow basic nutritional guidelines, unlike as you suggest I your article. All people should know their blood D levels and consult with their MD periodically – and consider if MD supports, daily supplementing to 2000 to 4000 IU, which is the Upper Limit. Whether or not this will attenuate – avoid or at least lesson – a Covid-19 infection will take time to sort, but appears reasonable for general health.


  12. This is quite informative , without doubt vitamin D is the answer .


    • For goodness sake, Vitamin D definitely isn’t “the” answer. It might be an answer that might reduce the death rate – but it’s definitely not the answer.


  13. Long article attempting to say that brown people are dying from covid because we lack Healthcare? What utter bs. Or that theres some racial conspiracy? 60% of deaths were nursing home patients wait let me guess you will debunk me as well. Covid is a biological weapon period.


    • Socio-economics are obviously a major factor in the death rate of darker skinned people in the UK, EU and especially the US. This is undeniable.

      The question is whether that’s the only causal factor, and with over 90% of the UK doctors that died in the first wave having been ethnic minority I don’t see how it’s plausible that socio-economics could be the sole cause of that. It certainly shouldn’t be assumed that it is.


  14. I found that eating, daily, 3 cups of Captain Crunch that were immersed in garlic laced heavy cream allowed me to survive 4 weeks in a Bronx nursing home, where 93 % of all the residents perished from Covid. I then discovered that viral shedding was coming from my ass onto the toilet seat and unfortunately, the cleaning lady died !! I am now so depressed that I force myself to watch Don Lemon as a self imposed cruel penance for my sin………Oh !!………..the HUMANITY !!!!

Just make sure it’s hight quality d3 bound with vitamin k2 and some kind of fat such as medium chain triglycerides. This ensures the d3 has a proper delivery system to get in the cells and work effectively.

    “For Better Science” haha. More like “For Better Bullshit”

    1) only the fringe weirdos, like exist in every camp, are claiming Vitamin D is a “cure”. The general much more consistent advice is “vitamin d lowers the risk of infection and severity of respiratory virus’s” which includes COVID, but we have research going back to the 80’s showing this is true for the common cold and flu as well.
    2) its been KNOWN for a long time that vitamin d is an important immunomodulator. It doesn’t “boost” your immune system any more than good sleep does, it helps modulate it properly. The body having a right-sized response is as important to getting over an illness as the severity of the virus itself.
    3) The reason Vitamin D hasn’t had more large scale clinical trials is because there isn’t money to be made from it. it’s off patent, anybody can make it, just get it from a reputable supplement company (yes those do exist).
    4) The risk is 0 when taken at or below the maximum tolerable intake for everybody. That max tolerable intake increases with age and obesity. There is no evidence that taking a reasonable amount of vitamin D is harmful, and plenty that it is helpful.

    This isn’t those zinc supplement studies where literally the only ones that showed efficacy were the ones paid for by the supplement company. Studies going back 30 years show that being sufficient in Vitamin D and/or adding supplementation reduce the risk for and severity of respiratory illness. None show any real risk until you supplement up to a level that is waaaaay outside the recommended limits. Many studies are also not discounting the role that poverty and healthcare access have at all like you imply they do, they mention those aspects as well as vitamin D status. They control for those factors as best they can. (yeah, epidemiology is inherently limited. That doesn’t make it bad as long as you consider the proper context, which you fail to do.

    Larger scale clinical trials certainly need to be ran, but when you combine the smaller scale studies with the decades of epidemiological evidence there is absolutely nothing wrong with recommending vitamin d supplementation with a reasonable expectation that it is helpful. You very clearly have an axe to grind here. I’m not even sure why this ended up in my feed or why I am bothering to comment.

It affects breast health, bone health, prostate health, cholesterol metabolism, mental health and immune health if not more. The effects via different receptors and conglomeration of other pathophysiologic processes sure to affect perhaps cytokine mediates storm. On off phenomenon at millions of receptor level: why is ignorance in science allowed to comment on articles.

  22. Low vitamin D is connected to the deregulation of our immune systems. It is not racist to state the obvious, scientific fact that people with darker skin in higher latitudes tend to produce less vitamin D than people with lighter skin. In fact, it’s absolutely insane to make the claims here that it’s all just “racism” to make some basic inferences from these facts. Maybe those inferences are wrong, but to accuse people of racism for making them is insane.

    Maybe the low vitamin D is only correlated to poor outcomes because of some other problem that causes this (obesity, etc). You could have made the argument that lighter-skinned people tend to have poor access to health care (especially in the US) which ultimately was the primary cause for their out-sized representation in the fatality statistics.

    What you are doing here is incredibly damaging to science and to the lives of people everywhere. You help to create an atmosphere of fear to even suggest certain possible treatments to experiment with based on fallacious accusations of “racism”. In your haste to paint these people as racists did it not occur to you that, if in fact they have a valid point, you made it that much harder for us to even find out? You are engaging in heresy-fighting tactics of the medieval Church here.

    I get that you want to combat systemic racism and end this rapacious socio-economic system we live in where God knows how many people are without health insurance during a deadly pandemic (and I think that’s why you see fatality rates so high for black and brown Americans). I am on your side here. But that’s not a science issue. Science has to deal with objective, measurable facts. We have to be willing to test predictions made by different models and those models need to be based on reality — and the reality is that vitamin D levels are at least correlated to poor covid outcomes and the the black population of the United States is almost twice as likely as whites to be deficient. Let’s test the hypothesis and stop impugning people of racism for even daring to acknowledge scientific facts regarding differences between the physiology of races.

  25. Bit of a Trumpian conflation of facts: while the rates in India may be high due to environmental conditions, it would be necessary to compare severity and mortality rates, not infection rates. I have seen no evidence vitamin D prevents COVID but some good evidence it regulates immune response and inflammatory (cytokine) response. In fact I came to this conclusion while watching Dr. Bruce Hollis lecture on vitamin D as a treatment for inflammation in the prostate, in which they also did extensive genomics and found that several genes were upregulated by the vitamin and differences between serum and cellular levels correlated. Since it is clearly an overreaction that is the most harmful aspect (at least until we get better genomics about lonh term effects of COVID) then regulating immune response and inflammation would seem like a no brainer. Of course with no patents on vitamin D (so far) there ain’t no money in dat…


    • Also, I have friends who’ve lived in India whose doctor there recommended their children take Vit D supplements because it’s apparently common to be low there. If anything, Leonid’s reference to Indian farmers – albeit sarcastic – seems to use an almost racist trope. India is a highly urbanised country with incredibly high population densities, as you say ideal for COVID spread. It’s pretty clear that such high densities, with people living and socialising in incredibly close proximity, are going to result in high infection rates and large numbers of deaths. Healthcare and socio-economics are also going to lead to a higher death rate. Then, figuring out the true death rate when testing is unlikely to be capturing enough cases is going to be difficult (although I haven’t kept up to date with the detail of the Indian situation). I daresay Leonid thinks this is all obvious and goes without saying but it gets rather lost in all the sarcasm.


  26. Sorry Leonid, but this article is a piece of crap as you’ve absolutely no understanding of the subject and hence what you are discussing here.

    First of all Vitamin D although called a vitamin is a hormone. And as hormones’ do it has a wide range of impact on organs of various systems. Vitamin D actions are mediated by Vitamin D receptor (VDR) that is mostly expressed on cells of endothelium. VDR regulates expression of 900+ genes and is major regulator of Renin-Angiotensin-Aldosterone system (RAAS) which comprises kidneys, adrenals, gastrointestinal tract, liver, heart and brain and is a major player in blood pressure regulation. Vitamin D also has direct impact on both innate and acquired immune system functions as well as metabolic processes.

    In humans most of the Vitamin D is synthesized in photochemical process that starts in the epidermis. UVB radiation from sunlight is absorbed by chemical that is converted into previtamin D that is later metabolized into active form of Vitamin D. Uptake from food is negligible due to limited amounts in the food as well as limited absorption from GI tract. The darker the skin the less UVB radiation is absorbed since melanin doesn’t absorb UVB radiation. Therefore people that live towards north have evolved to have lighter skin. Unless you live in Africa and supplement with Vitamin D chances are more than huge that you are Vitamin D deficient from October to March. Most of the people living in moderate climate zones (like southern Spain or Central Europe) have too dark skin and have too little sun exposure to synthesize enough Vitamin D during winter months. Vitamin D deficiency is associated with RAAS malfunction via increased Angiotensin II levels in plasma.

    Another thing regarding COVID-19 is the ACE2 gene and therefore receptor expression. It’s well known fact that ACE2 gene expression is more expressed in people of non-European ancestry. ACE2 is a heavy player in COVID-19 severity as infection with SARS-CoV-2 means more ACE2-receptors lost upon infection. Losing ACE2 receptors results in Angiotensin II increase (just the same way as low Vitamin D results in more Angiotensin II) which in turn drives formation of microthrombus, endothelial dysfunction, DVT and pulmonary embolism which we see in severe cases of COVID-19.

    Vitamin D is more than capable of bringing this pandemic under control but I guess you would like to have your $5 instead.

    • Vitamin D won’t bring this pandemic under control. It might reduce the death rate and save lives, but the idea that it might be some panacea is just bunk. The pandemic would still be happening if we all had optimal Vit D levels.


      • Um, the virus can spread and still infect intermittent people or a smaller fraction, and not be a pandemic. Personally I think the pandemic phase would be gone if everyone brought their blood levels of 25-OHvitamin D to 60 ng/L, but would also still advocate other easy measures.

        I personally have multiple risk factors and utilize multiple “mega” nutraceuticals including time release vitamin C 2-4 g TID, quercetin, magnesium chloride, and zinc. My wife and I take 10,000 iu vitamin D per day.


      • Although the existing studies are poor, they show either a weak effect or no effect on transmission. If the effect on transmission reduction were as strong as you claim then that effect would have shown in the studies we already have. As far as I know, it doesn’t.

        What the existing studies don’t disprove – but what is supported by existing knowledge of biochemistry and immunology, as well as statistics such as the proportion of UK ethnic minority doctors that died of COVID-19 in the first wave (over 90% were ethnic minority) – is that having optimum levels of D might reduce the risk of severe disease and death.

        Those are two very different claims, and people on both sides of this debate are conflating the two which is massively unhelpful.

    I can’t decide which is worse from the this “author”, the partisan sanctimoniousness or his insufferably arrogant attitude, though I suppose these are linked.

    It’s fairly simple and obvious. Hi Vitamin D levels (I maintain a 45-50 range) via supplements/sun exposure and moderately healthy lifestyle choices make all the difference in the world for not only Covid, but most health related questions. Duh.

    This is NOT “systemic racism” you LYING schmuck, but yeah, keep contributing to the “culture fire” started by hard leftists to destroy this society from within. Your editorializing would make PRAVDA proud.

    One paragraph is all that’s needed:

    Maintain minimum Vitamin D level of 30+ (though 40+ is encouraged via a inexpensive supplements and an average daily exposure to natural sunlight of 30-45 minutes per day). Moreover healthy dieting, moderate exercise and adequate nightly sleep contribute greatly to one’s overall immune system and general health. Darker skinned people are generally lower in vitamin D levels due to higher melanin levels vis-a-vis lighter skinned people.

    Absence of evidence, (or disagreement with evidence, ignorance of evidence, or ), isn’t the same thing as evidence of absence. With all due respect to Mr. Schneider’s credentials for evaluating science, there are scientists and pubic health researchers with much more impressive credentials, that strongly advocate for the use of Vitamin D and have presented compelling evidence.

    Has anyone seen this evidence from Dr. Rhonda Patrick?

    Dr. Patrick, Ph.D has published a prolific amount of research on the functioning of Vitamin D at the bio-molecular level, and she is easily recognized as one of the world’s leading authorities on the micronutrient.

    In the context of Covid, she desribes how Vitamin D normalizes the renin angiotensin system, by upregulating the ACE 2 receptor and downregulating renin, which protects against ARDS (Acute Respiratory Deficiency Syndrome) and acute lung injury. She also presents evidence, that Vitamin D in the blood, by upregulating soluble ACE 2 – which then binds to and sequesters viral particles – is another mechamism of protection against severe infection. She also provides recommendations about supplementation and maintaining proper Vitamin D levels, and she reveals her own supplementation protocol.

    To anyone reading this, please do yourself a favor: Stop reading pointless, rhetorical articles and start getting the valuable information you need to protect your health from real public health authorities like Dr. Patrick.

This is the most unscientific and illogical argument for ignoring science, published studies, and common sense I have ever read. Vitamin D is probably the most important nutrient the body needs and uses. So important it is that every single nucleated cell int he body has a Vitamin D receptor in it and some have multiple receptors. In fact all the so called co-morbidities of COVID-19 “disease” are vitamin D deficiency problems. And Vitamin D is not even a vitamin, which he is not even aware of. It is a steroid hormone and BTW it is almost impossible to have any toxicity from it, since it is so tightly regulated in the body. The only way would be to take huge doses of calcitriol, not vitamin D3 or even 25(OH)D. What a jackarse.

For reasons given in the comments above this article is completely unhelpful in doing so as it’s so hard to unpick the snide ranting from the science. Not least because you seem to skim over the science, since you seem to think it’s obvious how bad the science is. But it’s not. I’d much prefer it if you’d walk us through why you think the science is bad and leave the ranting to insinuation, rather than the other way round.

    As you admitted in a Twitter exchange, you aren’t a Vit D expert. Yet you’re gunning for people who are; you’re cherry picking the bad lines of argument while ignoring the good ones; and you’re committing the same fallacies yourself. In particular, using the fact that a few people are taking way more D than they’re supposed to and getting sick as an argument against the idea that D supplements are sufficiently low risk to be used while the evidence is weak is particularly bizarre.

    And then your sarcastic comments about there being no COVID in Marseille or Africa is even more odd. Noone sensible is suggesting that having sufficient D will provide 100% protection. But equally, just because a country is sunny doesn’t mean people aren’t deficient. On the contrary – in my experience, people in sunny countries tend to spend a lot of time indoors with their air conditioning. You seem to be making a lot of bad assumptions that are as fallacious as the people you’re criticising.

    Then there’s this strange sentence about Fauci:
    “But old age is about much more than maybe lacking some Vitamin D” – Obviously!
    “so the causality with COVID-19 severity is very strenuous there at best” – What? Why can’t it be both?

    Even if you end up being proven right about Vit D once we have enough good evidence, I really don’t see how these ranty articles are contributing to Better Science at all. As someone who’s trying to figure my way through the evidence I’d love to see articles from you that did.


    • So you say Dr Michael Holick is expert for Vitamin D whom I must take seriously and respectfully? Same goes for Dr Joachim Son-Forget, I presume?
      Do answer this, please.


      • No. I was referring to the endocrinologists you named and criticised by implication.


      • What about these two other experts I named then? No opinion?


      • You named a lot of scientists of varying levels of expertise in this field – I don’t have time right now to reread the article again as my four year old wants attention but I’m guessing you’re referring to two you named supporting your view that the Vit D hypothesis is bunk. If so, then no, I don’t really have an opinion because I completely accept that expert opinion on this is divided just as I accept that the evidence is weak and inconclusive – but only insofar as it’s an absence of evidence, rather than evidence of absence. As far as I can see, the hypothesis and mechanism both remain plausible and the question remains open.

      • I am sorry to have disturbed you, my sincere apologies. Now I see you were so busy to put me in my place even though you have no idea which experts you have been defending from my ill-informed attacks. It would have taken you less time to look up those text bits above on Holick and Son Forget than to write your comment about your busy schedule. Hilarious.


      • Leonid, why do you take this acerbic, sarcastic approach that assumes everyone who questions you or disagrees with you in any way is arguing in bad faith? It’s really unfortunate.

        You didn’t disturb me, I wanted to make time to reply but ran out of it trying to reread your article. My daughter is now happy on a video call to family so I have a bit of time again.

        It didn’t occur to me that you were referring in your comment to Son-Forget and Holick because the former doesn’t seem to be an expert in this field and the latter appears to engage in questionable research practices, as you have done such an excellent job of highlighting. I therefore don’t really consider him to be an expert.

        I presumed therefore that you were referring to two other actual experts, and after skimming back through the article I couldn’t find others but thought I must have been missing something. A genuine misunderstanding, but one which I’m afraid is rather symptomatic of your approach I’ve noticed in your writing where you seem to assume that what’s obvious to you must be obvious to others.

        This is all a real shame. There’s clearly a lot of bunk around Vit D, just as there is around all sorts of things in science and medicine. But there should be room for nuance, and there should be room for scientific uncertainty. Fundamentally, it doesn’t follow that just because dodgy or unqualified people advocate a hypothesis with bad science that the hypothesis is somehow undermined.


      • That is a bit unfair, my first reply to your asked for your opinion on Holick and Son-Forget specifically. Look up.


      • I see. I thought my one word answer had covered that, which is why I thought you were referring to other experts. But to elucidate: no, I don’t think you should take either Holick or Son-Forget seriously – or, in the case of Holick, respectfully (I’m less sure whether Son-Forget deserves disrespect).


      • You tell me this regression curve by Son-Forget is perfectly fine, then?

        Ok. If you say this person deserves respect as a scientist, I trust you.
        Otherwise, why don’t you, you know, read my article before telling me how bad, wrong and disrespectful towards experts it is?
        There is only one study which pretends to be a clinical trial, and it is quite problematic in several aspects. Other “papers” are nothing but untenable Just So associations (except of Holicks’, that one is probably just made-up).

      • No, it’s pretty obviously absurd. But it’s a leap that just because I’m not sure whether he deserves disrespect I’d think that graph is OK. My only point there is that I think it often isn’t useful – and often isn’t justified – to use disrespect when pointing out that someone’s wrong about something. Maybe it’s justified in Son-Forget’s case but I don’t think you were that disrespectful, actually, as it was a real corker.

        I was just thinking about this though before I saw your reply this morning – and, actually, what I’d forgotten when I replied last night was Son-Forget’s quote tweet reply to you. That’s just not acceptable coming from a parliamentarian IMO.

        Anyway, really – I have no issue with your criticism of these two. I accept I should have been clearer in my first post that the experts I was referring to were Prof Schatz, Biesalski and Gennari. I’m not defending them either though – all I’m saying is that I think their credentials mean their comments, or recommendations, deserve more than simply out-of-hand dismissal. It’s in particular not clear why they’re so wrong to take the study seriously which you refer to as “braindead and bigoted.” I’m sure you’ve got good reasons for saying that, it’s just not clear to all your readers or to me.

  41. The French Académie Nationale de Médecine has recommended vitamin D since May (see, though the French government has not followed suit on that yet. One of the statements of the recommendation is: “Vitamin D cannot be considered as a preventive or a curative treatment for CoV-2 SARS infection. However, by mitigating the inflammatory storm and its consequences, it could be considered as an adjunct to any form of therapy.” Neither preventive, nor curactive, but it could, maybe, perhaps help? Yeah, it “could”. That’s enough to make it 21st century science.


  42. I have been a passive follower of this subject since early April which I obtained a U.K. study associating latitudes and resulting higher rates of Vitamin D deficiency. They hypothesis they present to apply equally to Influenza and Covid.One of the factual parts of this study discovered that patients presenting with ARDS (ventilator candidates) 90% of them were Vitamin D deficient. A co-worker with a hospital director friend who was a member of a forum of 30 treating physicians in early April liked three things in their treatments of their patient. HCQ, Vitamin D, Zinc in early April. The U.K. issued a Public Health Notice around 5/1 for the entire populace to supplement with Vitamin D at a level of 400 IU.
    I got a copy of a Philippine study, 222 patients, Conclusion deficient 30 ng/ml mild disease. 7 times less likely to have Critical disease if one is not deficient. Four times less likely to have severe disease if one is not deficient. But when looking at the tables the insufficient group was mixed. As ones level increased the level of severity decreased. I have read where there is a coefficient of additional protection for each nanogram increase in Vitamin D levels. There is an Indonesian study. Group of 50 deficient treated with Vitamin D 2 persons required ICU, 2nd group of 26 not treated with Vitamin D 13 persons ended up in ICU.
    University of Chicago Study published 9/3. Actual study was performed during the month of March when they was a lack of testing. They only saw sick people. They hypothesized people not deficient could be immune. But the observations in this study were well defined. Vitamin D deficiency with critical disease and death. Boston University study. Some are discounting it because Holick is being called a shill for the Vitamin D industry and Quest Diagnostics does testing.
    190,000 blood draws and they had 30% of Caucasians found to be deficient. *2% of African Americans to be deficient.
    African Americans have a high rate of critical disease and death. As to some of the other possible conclusions I am a little more skeptic. They actually believe the possibility that very high levels of Vitamin D possibly offer immunity.
    Personally I think a hypothesis where those that are infected but are asymptomatic may have higher levels.
    I also wonder if it is possible that if the previous sentence is true then why do we need Covid or Influenza vaccinations. After all, a vaccination is not a cure. Does not prevent infection just, hopefully, makes it mild.
    What I want to see. A nationwide trial for everyone testing positive to also get a blood draw to ascertain Vitamin D levels.
    I found something tonight that another enzyme may need to be included as well. People hospitalized will have their disease charted in the hospital. For those told to self quarantine give them a check off form to complete daily of any symptoms experienced. Exact levels of blood serum for each individual to be tracked by that level. Not just grouped in three categories. Stress compliance to complete forms to be mandatory. Pick them up, if necessary. We could have a million enrollees in less than a month. One would think that would get the corrupt CDC, NIH to ake notice. Not double blind, placebo controlled, just a large observational trial. What they hate. I don’t think they can ignore the results.
    And yes, I believe they to be criminal organizations. It’s criminal with the information they have received, albeit not perfect, is displaying a relationship between severity and deficiency that they are not standing on a stage warning people to supplement and get tested. National defense act to increase supply of supplements. 95% of ingredients are imported.


    • Another otherwise good comment undermined about nonsense about vaccines and and immunity. In most cases, most vaccines (except flu and rabies) do completely prevent infection: it’s flat wrong to say “After all, a vaccination is not a cure. Does not prevent infection just, hopefully, makes it mild.”
      It’s also flat wrong to claim high serum levels of Vit D offer “immunity”, or anything similar. At best it might reduce the risk of infection and severe disease, but the former seems unlikely from the existing studies. What is possible – and isn’t answered by the existing studies – is that the healthy levels of Vit D (whatever they are, and it may be that current thresholds are inadequate) reduce the risk of severe disease. It’s therefore important to separate the two, and disassociate the plausible hypothesis from nonsense about Vit D possibly offering immunity.

    Publisher Frontiers was willing to publish (“Systems Thinking About SARS-CoV-2”).

    This peer-reviewed article of the astronomer Rainer Klement contains the following sentences:

    “Unfortunately, we live in an age in which fewer and fewer scholars have serious competence beyond their own increasingly narrow field of research.”

    “Unfortunately, the computer models that had been used to justify the lockdown interventions in many Western countries had not taken these immune responses offering partial protection of a significant percentage of the population into account”

    “Furthermore, the public is rarely informed that an optimally functioning immune system requires the presence or absence of certain factors.”

    “The strongest evidence to date is available for vitamin D whose main natural supply is not through diet, but solar UV-B radiation on the skin (path B in Figure 1). Higher vitamin D levels have been linked to lower COVID-19 incidence, death rates and hospitalizations in epidemiological studies (33–35). First clinical data suggested that higher vitamin D levels are associated with less severe courses of COVID-19 (36, 37). A recent randomized controlled trial has shown a highly significant benefit of high vitamin D supplementation in COVID-19 patients: out of 50 patients receiving 25-hydroxyvitamin D in addition to standard treatment2 only one required intensive care unit admission compared to 13 out of 26 patients having not received vitamin D (p < 0.001) (38). Given the cost-effectiveness and safety of vitamin D and other immune-supporting nutrient supplements, some authors have rightfully argued that public health officials should encourage their adequate intake through a healthy diet and supplementation (26, 27).”

    “Enforced prolonged wearing of face masks is also problematic, as demonstrated by Daniela Prousa who revealed that ~60% of the German population experienced severe psychosocial problems already 5–7 weeks after installment of a public mask wearing decree (43)”.

    “The “collective statistical illiteracy” of health care professionals, journalists and politicians (51, 52) is nothing more than a lack of transdisciplinary knowledge in mathematics and statistics. It is contributing to incorrect information about the spread of the SARS-CoV-2 with the effect of increasing both the public fear and impulsive actions from governments (…)”

    Frontiers was willing to publish these texts after an approval by three peer-reviewers and one editor.

    There is at the bottom of this article a comment from Linda L Benskin (“This is a positively brilliant indictment of the current state of affairs. Thank you so much for articulating the underlying problem so well. (….) The Great Barrington Declaration was dismissed out of hand because these leaders are unable to grasp what the framers of the document intended – it requires looking at more than one aspect of the problem at the same time.”).

    Author Rainer Klement is also known as one of the 22 authors of the ‘External peer review of the RTPCR test to detect SARS-CoV–2 reveals 10 major scientific flaws at the molecular and methodological level: consequences for false positive results’, see for backgrounds.


    • All the nonsensical scepticism about the effectiveness about the PCR test, masks and lockdowns achieves is to discredit otherwise good points about Vit D. It’s not helpful, and as someone who advocates a very narrow, specific point about the Vit D hypothesis and the risk/benefit calculation of supplementation I feel I need to explicitly disassociate myself and the points I’ve made from such quackery.



    It’s a fact. That whenever you challenge the Establishment/Orthodoxy you are going to become a target. It’s easy to peddle all kinds of racist nonsense wrapped up in equations, models, and Stats. The history of science is full of it.Race and IQ attract nutters and racists. Science is not value-free, completely objective, and racially neutral.
    I’m surprised that Black Lives Matter has fallen for the Vit D theory. The theory is ideology. But as old Marx said, “the ruling ideology is the ideology of the ruling class. The way to protect the BAME community is to provide socialized medical provision, therapeutics, and care, free at the point of use and not just a bloody Vit D supplement.

    Naomi Wolf writes on 7 January 2021 in a thread at

    “Just had an interview scheduled with Dr Simon Goddek, the post-doctoral researcher at the Faculty of Mathematics and Statistics in the field of biotechnology, at an unnamed Dutch university. This researcher has been publicly pointing out that the paper that the PCR test as the gold standard underlying global “lockdowns” was passed after maximum ONE day of peer review, as opposed to the average at that same journal of 172 days in 2019. Also that several authors have conflicts of interest. Unfortunately we were forced to cancel because he was strongly advised by his university to maintain silence and not speak publicly — to step back from this issue. I learned from a source that his university was heavily assailed by many complaints. Other scientists who have signed the review criticizing the PRCtest, the “Retraction Request Letter”, a critique that got worldwide attention, have also been bombarded with attacks, their relatives are being called at night, and their universities assailed. Some are at risk of losing jobs. Even former employers are being harassed. I note: scientists around the world are being silenced and harassed if they speak up in normal criticism of the scientific methods or conclusions used to advance the lockdown agenda and COVID testing. This is not post-enlightenment scientific discourse, this is how scientists are treated in police states and totalitarian societies. I also note that this strategy of repetitional attacks in which organized campaigns of harassment and complaint are aimed at people’s publishers, universities and employers in order to silence them, is a tool being directed systematically against commentators in what should normal debate and open dialogue. It happened to me, to Dr Michael Mann, and now these campaigns of harassment are being directed at scientists whose findings reveal possible huge flaws in COVID related research. When universities and publishers give in to this kind of bullying and harassment, I know it is tempting to do so and step out of the line of fire, but from having studied closing societies, it will be six months before they too are forced to swallow a party line and before all real scientific enquiry, all real journalism, all open debate, is closed forever. I beg this unnamable university to allow this analyst to speak to me and to the world which wants to hear what he has to say as the Enlightenment taught us was valuable in assessing data, information.”

    That’s of course once again a very unfortunate situation.

    Which unnamed university? The University of Harderwijk? (“The university of Harderwijk did not have a good reputation, because of its low standards.”, source Wikipedia). Or maybe the University of Franeker?

    Roman Zieliński is “a professor of biology with a specialization in genetics with almost 40 years of experience in research and teaching.” He “created from scratch the Department of Genetics at the University of Szczecin, which was one of the first units introducing PCR analysis into genetic research (1995).”

    A long interview with Roman Zieliński is posted at This interview contains remarkable views.

    “Meanwhile, it is not the age, but lifestyle that is the main risk factor. Our grandmothers, who rarely got sick, knew about it, but ate homemade products made with vegetables collected in their own garden. (….) Dr. Marek Wasiluk in an extensive article on Onet considers obesity as one of the causes of the acute course of COVID. (….) Not only do we have a serious disease called chronic medical failure syndrome, but we also have a reduced immunity as a result of many months of wearing microbial incubators on the face, sitting at home, and therefore limiting the intake of vitamin D. Therefore, let’s not go crazy and lead a healthy lifestyle without masks and with lots of activity. I have already started and for this occasion I prepared 30 kg of sauerkraut. If so, I will survive the winter by supplementing myself with a self-made “vitamin bomb”.”

    “Unfortunately, in the era of Covidianism, the basic principle that has been in force for centuries was forgotten. Recommendations have been made that contradict the ancient knowledge and essence of a man as a biological species. Ban on leaving the house, face masks, excessive sterilization of rooms and body – these are recommendations that lead to increased susceptibility to disease, and not those that protect against them.”

    “The orders to wear masks, which constitute a breeding ground for microorganisms, and the prohibition of walking, singing, dancing, meetings, together with coercing unwanted therapies and threatening with vaccines is unprecedented violence, which in fact leads to the death of a significant part of the population.”

    “We found out that this preparation, called a “vaccine”, is a product of genetic engineering in the form of a recombinant RNA construct. (…). This specimen cannot be called a vaccine. This is not a vaccine in its essence. I call it an mRNA construct, recombinant RNA, a product that is genetically engineered.”

    “The 20-year patent protection for the flu vaccine had ended and the flu had to disappear. COVID has appeared in its place.”

    “We were only surprised that no Polish scientist agreed with us, but determined our ignorance, on the contrary.”

    Rainer Klement, author of (“Systems Thinking About SARS-CoV-2”), see my earlier posting, is one of the 22 authors of a new preprint at (archived version at ). This preprint “Addendum to the Corman-Drosten Review Report” was published on 11 January 2021. It is stated at page 41 of this new preprint:

    “Even if the RT-qPCR test was optimal and had theoretically sensitivity and specificity of 100%, it is medical malpractice to use RT-qPCR and other rapid tests outside the need for specific antiviral therapy in symptomatic or severely ill hospitalised patients. Interpreting positive tests as ‘medical cases’ without consideration of internal controls and viral Ct with clinical context, nor consideration of other viruses or diseases that cause similar symptoms as COVID-19, enables politicians to practice medicine on entire populations. This lack of clinical integration has led to problems in the past.”

    Frank Visser states at about this new preprint:

    “Methinks the Consortium would feel competent to create the perfect PCR test for SARS-CoV-2, but paradoxically in the end they don’t care about any PCR test improvements, for in their understanding they are useless for large-scale diagnosis and surveillance of an emerging pandemic. The whole operation by the Consortium is done in bad faith: critiquing an early PCR test for SARS-CoV-2 in the strongest terms without any intention of improving on it.”

    Simon Goddek tweeted a few hours earlier: “In my spare time, I love reading scientific papers and creating causal-loop-diagrams to better understand the metabolism. My message to you is that the shown green factors improve health whereas red factors should be avoided. #COVID is standing no chance against a healthy body!”

    Naomi Wolf has in the meanwhile posted at DailyClout (“a platform that empowers real people to build & exert real political clout, turning them into do-it-yourself lobbyists, journalists & leaders.”) an interview with Simon Goddek, see This video has the title ““Dr. Naomi Wolf and Academic Whistleblower Dr. Simon Goddek”.

    Do the statements of Simon Goddek mean that there are valid motives to argue that Simon Goddek is a covidenialist?

    Marjolein Doesburg-van Kleffens is one of the 22 authors (‘experts’) of the Corman-Drosten review report which was submitted to the journal Eurosurveillance in the end of November 2020.

    The review lists “Dr. Marjolein Doesburg-van Kleffens (MSc, PhD), specialist in Laboratory Medicine (clinical chemistry), Maasziekenhuis Pantein, Beugen, the Netherlands” as information about this author. Source:

    It seems to me that this means that readers of this review can assume that this review is endorsed by the affilation “Maasziekenhuis Pantein, Beugen, the Netherlands”, the employer of Marjolein Doesburg-van Kleffens. Source:

    This point of view is supported by the lack of a disclaimer in the review in which it is stated that this hospital does not endorse the statements and views in this review.

    The Corman-Drosten review report contains towards the opinion of the Outbreak Management Team (the advisory board of the Dutch government in regard to the covid-19 pandemy) fakenews (‘desinformatie’) about the reliability of the PCR test and/or about the covid-19 pandemy. Source:

    “Berichtgeving COVID-19. Het OMT maakt zich zorgen over berichten in de media dat SARS-CoV-2 niet echt zou bestaan of dat de PCR geen betrouwbare test is. Het OMT vindt het wenselijk dat hierover duidelijk wordt gecommuniceerd en dat hierover stelling wordt ingenomen door de beleidsmakers, waarbij men zich uitspreekt dat bewuste desinformatie onacceptabel is.” (page 9).

    It is therefore towards my opinion highly remarkable that a Dutch hospital is endorsing the views and statements in this review, and in particular given the statements about covid 19 at the website of this hospital (all of them fully in line with the policy in The Netherlands). Source: (in Dutch, with a reference to ).

    I have thus contacted the hospital about this topic. I received on 11 December a response from Olga ten Wolde, spokesperson of this hospital.

    “Mevrouw Doesburg-Van Kleffens is bij deze review betrokken vanuit haar onafhankelijke wetenschappelijke achtergrond en niet als werknemer van het Maasziekenhuis. De affiliatie in de review is vermeld omdat dit vereist is bij een dergelijke publicatie.”

    So Olga ten Wolde is claiming that it was mandatory for Marjolein Doesburg-van Kleffens to list the name of her employer as affiliation at this review.

    Olga ten Wolde told me in the same e-mail: “Aangezien het geen publicatie van het Maasziekenhuis is en wij er niet bij betrokken zijn, kunnen wij er ook geen afstand van nemen. Wij zullen dit daarom niet op onze website vermelden.”

    So Olga ten Wolde is claiming that the Corman-Drosen review which was submitted to Eurosurveillance is not a publication of this hospital and that is therefore not possible to post a disclaimer on the website of this hospital in which it is stated that this review contains fakenews about the covid-19 pandemy.

    I have asked Olga ten Wolde to provide me evidence for her points of view, and in particular because I was unable to find at that it is mandatory for all authors to list the name of their employer as affiliation. Olga ten Wolde and others at this hospital have until now failed to send me this evidence.

    Olga ten Wolde wrote to me on 21 December: “Wij zullen overigens niet opnieuw op berichten met een vergelijkbare inhoud reageren. Dit doen we om herhaling over en weer te voorkomen.”

    So Olga ten Wolde has choosen not to rebut my arguments that such a obligation does not exist (for example illustrated by the information about several authors of the Corman-Drosten review).

    Marjolein Doesburg-van Kleffens has studied chemistry at Leiden University and holds a PhD from Erasmus University, Rotterdam. Source: (“The IGF system during growth and differentiation of the mouse”).

    Her ResearchGate profile at states at the moment “She’s currently not involved in a research project.”

    Others who are able to locate this obligation at ? Anyone any idea why Marjolein Doesburg-van Kleffens has not used her other affiliation (.i.e. member of the board of Antroposana, source )?
