To summarize, the review examined various studies that compared median serum vitamin D levels to factors such as COVID-19-positive cases, the severity of the infection, disease survivors, deaths, levels of inflammatory cytokines and markers such as C-reactive protein, and the number of days spent in the hospital.

Overall, the results reported no significant associations between vitamin D levels and COVID-19 severity, mortality, or hospitalization duration. Vitamin D deficiency seemed to be associated with the likelihood of being COVID-19 positive, but the nearly significant association decreased when examined at a larger scale.

Another one bites the dust.

Vitamin D supplements are good for a lot of things but apparently COVID prevention and cure isn’t one of them.

  1. My recollection of the initial vit D recommendation was that they were not finding people acquiring covid that had a high level of Vit D in their system. What they are talking about here is not the same subject. Is this a deliberate sleight of hands move?

    • I initially read it similar to you. But if you read it carefully they are addressing both. With better statistics they found there probably isn’t any preventive value with vitamin D as well as curative value.

  2. My D level was 85 before the shot(s) and 65 after. I felt no effects at all from the shot(s). D level matters, but was not captured in this study. Not saying it is a cure, but it doe matter.

  3. Vitamin D levels are a marker of general health and immune system health.
    The better those two are the less of an issue ANY virus is too your overall
    health. Covid is merely another version of the Coronavirus….of which there are dozens and dozens.

    There seems to be a correlation between vitamin D deficiency and likelihood of developing severe illness of COVID-19 when observing studies individually. However, when comparing studies on a larger scale it seems that the significant difference seems to fade.”… Research Square.
    If you flip it over and insert ” Covid vaccination”, for Vitamin D. It kind of gets interesting.
    Sometimes your number is just up.
    One thing we know for sure about Covid. Klaus and friends murdered a lot of people with it. And made a tidy profit to boot.

  5. A couple of things.
    This is a pre-print, not been seriously reviewed.

    Second, unless I’m totally missing something they don’t say which studies they used. There were a number of them that were done a while back (when it looked like D3 was a major player) which were very badly designed and used methods that were known to not produce good results, such as administering a large single dose (a bolus) of D3 after infection, rather than having adequate D3 in the system prior to infection. They were clearly designed by Pharma to minimize the utility of D3. If those any (or many) of those studies were included in this meta-study, then they’d skew the “average result” toward “high D3 doesn’t help,” and even then they say the effect is “almost significant” (i.e., something that is likely so, but not quite into the mathematically “highly probable” realm) .

    Third, they say they have no conflicts on funding, but they do not identify their funding.

    Fourth, and perhaps most importantly, it should be noted that a lot of people who catch the flu or covid end up dying from follow-on respiratory infections like pneumonia, and this study points out More importantly, this meta-analysis also looked at the effects of Vitamin D supplementation on acute respiratory infections, and found that there was a statistically significant difference between treated and untreated; and those who were given the supplementation had a reduced incidence of acute respiratory tract infections (6). Their results showed that daily and weekly Vitamin D supplementation with multiple additional doses provided significant protection against acute respiratory tract infection. A single bolus of Vitamin D supplementation was not enough to provide a protective effect, however (6).

    So I’d still recommend taking a regular D3 supplement, preferably with K2 and sufficient Mg in your diet.

    • According to the NIH, respiratory tract infections were the primary killers in the Spanish Flu in 1918-20.
      IIRC, they basically concluded that bacterial infections piggybacking on virus infections were the main problem. Also, they concluded that WEARING MASKS was a big part of the cause of those infections taking hold. Perfect breeding ground conditions.

      Two papers, one on the bacterial problem, and the other on the masks, and they disappeared during the covid crap.

  6. Another meta study was published late last month at
    Does vitamin D supplementation reduce COVID-19 severity?: a systematic review

    Background: The evidence regarding the efficacy of vitamin D supplementation in reducing severity of COVID-19 is still insufficient. This is partially due to the lack of primary robust trial-based data and heterogeneous study designs.

    An aside: You have to ask yourself why this is the case, for a disease so hugely important we shut the world down for it, given the very early indicators that vitamin D was a potentially important factor. There are no benign reasons to explain this failure, IMHO.

    Aim: This evidence summary, aims to study the effect of vitamin D supplementation on morbidity and mortality in hospitalized COVID-19 patients. Design: Evidence summary of systematic reviews.

    Methods: For this study, systematic reviews and meta-analysis published from December 2019 to January 2022 presenting the impact of vitamin D supplementation on COVID-19 severity were screened and selected from PubMed and Google scholar. After initial screening, 10 eligible reviews were identified and quality of included reviews were assessed using AMSTAR and GRADE tools and overlapping among the primary studies used were also assessed.

    Results: The number of primary studies included in the systematic reviews ranged from 3 to 13. Meta-analysis of seven systematic reviews showed strong evidence that vitamin D supplementation reduces the risk of mortality (Odds ratio: 0.48, 95% CI: 0.346-0.664; P < 0.001) in COVID patients. It was also observed that supplementation reduces the need for intensive care (Odds ratio: 0.35; 95%CI: 0.28-0.44; P < 0.001) and mechanical ventilation (Odds ratio: 0.54; 95% CI: 0.411-0.708; P < 0.001) requirement. The findings were robust and reliable as level of heterogeneity was considerably low. However the included studies were of varied quality. Qualitative analysis showed that supplements (oral and IV) are well tolerated, safe and effective in COVID patients.

    Conclusion: The findings of this study show that vitamin D supplementation is effective in reducing the COVID-19 severity. Hence, vitamin D should be recommended as an adjuvant therapy for COVID-19.However, more robust and larger trials are required to substantiate it further.

  7. Here are my stars of “like” for Rolf’s responses.

    I’m of like mind and of like logic with Rolf on these topics.

  8. BTW, The primary author of those two missing NIH papers were Dr Fauci. The pub dates were about ’08 and ’17.
