SCIENTIFIC EVIDENCE INDICATES VITAMIN D REDUCES COVID-19 INFECTIONS & DEATHS: VITAMINDFORALL CAMPAIGN

VitaminDforAll.org - In an open letter being sent to world governments on the 21st December, 2020; 120 health, science and medical experts from the UK, US and Europe said there is clear scientific evidence that vitamin D reduces COVID-19 infections, hospitalisations and deaths.


The Letter


To all governments, public health officials, doctors, and healthcare workers,

Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes.

Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence1 shows that:

  • Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
  • Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
  • Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment.
  • Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
  • Causal inference modelling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.

Vitamin D is well known to be essential, but most people do not get enough. Two common definitions of inadequacy are deficiency < 20ng/ml (50nmol/L), the target of most governmental organizations, and insufficiency < 30ng/ml (75nmol/L), the target of several medical societies & experts.2 Too many people have levels below these targets. Rates of vitamin D deficiency <20ng/ml exceed 33% of the population in most of the world, and most estimates of insufficiency <30ng/ml are well over 50% (but much higher in many countries).3 Rates are even higher in winter, and several groups have notably worse deficiency: the overweight, those with dark skin (especially far from the equator), and care home residents. These same groups face increased COVID-19 risk.

It has been shown that 3875 IU (97mcg) daily is required for 97.5% of people to reach 20ng/ml, and 6200 IU (155mcg) for 30ng/ml,4 intakes far above all national guidelines. Unfortunately, the report that set the US RDA included an admitted statistical error in which required intake was calculated to be ~10x too low.4 Numerous calls in the academic literature to raise official recommended intakes had not yet resulted in increases by the time SARS-CoV-2 arrived. Now, many papers indicate that vitamin D affects COVID-19 more strongly than most other health conditions, with increased risk at levels < 30ng/ml (75nmol/L) and severely greater risk < 20ng/ml (50nmol/L).1

1 The evidence was comprehensively reviewed (188 papers) through mid-June [Benskin ‘20] & more recent publications are increasingly compelling [Merzon et al ‘20Kaufman et al ‘20Castillo et al ‘20]. (See also [Jungreis & Kellis ‘20] for deeper analysis of Castillo et al’s RCT results.)

2 E.g.: 20ng/ml: National Academy of Medicine (US, Canada), European Food Safety Authority, Germany, Austria, Switzerland, Nordic Countries, Australia, New Zealand, & consensus of 11 international organizations. 30ng/ml: Endocrine Society, American Geriatrics Soc., & consensus of scientific experts. See also [Bouillon ‘17].

______________________________

Evidence to date suggests the possibility that the COVID-19 pandemic sustains itself in large part  through infection of those with low vitamin D, and that deaths are concentrated largely in those with deficiency. The mere possibility that this is so should compel urgent gathering of more vitamin D data. Even without more datathe preponderance of evidence indicates that increased vitamin D would help reduce infections, hospitalizations, ICU admissions, & deaths.

Decades of safety data show that vitamin D has very low risk: Toxicity would be extremely rare with the recommendations here. The risk of insufficient levels far outweighs any risk from levels that seem to provide most of the protection against COVID-19, and this is notably different from drugs & vaccines. 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. There is no need to wait for further clinical trials to increase use of something so safe, especially when remedying high rates of deficiency/insufficiency should already be a priority.

Therefore, we call on all governments, doctors, and healthcare workers worldwide to immediately recommend and implement efforts appropriate to their adult populations to increase vitamin D, at least until the end of the pandemic. Specifically to:

  1. Recommend amounts from all sources sufficient to achieve 25(OH)D serum levels over 30ng/ml (75nmol/L), a widely endorsed minimum with evidence of reduced COVID-19 risk.
  2. Recommend to adults vitamin D intake of 4000 IU (100mcg) daily (or at least 2000 IU) in the absence of testing. 4000 IU is widely regarded as safe.5
  3. Recommend that adults at increased risk of deficiency due to excess weight, dark skin, or living in care homes may need higher intakes (eg, 2x). Testing can help to avoid levels too low or high.
  4. Recommend that adults not already receiving the above amounts get 10,000 IU (250mcg) daily for 2-3 weeks (or until achieving 30ng/ml if testing), followed by the daily amount above. This practice is widely regarded as safe. The body can synthesize more than this from sunlight under the right conditions (e.g., a summer day at the beach). Also, the NAM (US) and EFSA (Europe) both label this a “No Observed Adverse Effect Level” even as a daily maintenance intake.
  5. Measure 25(OH)D levels of all hospitalized COVID-19 patients & treat w/ calcifediol or D3, to at least remedy insufficiency <30ng/ml (75nmol/L), possibly with a protocol along the lines of Castillo et al ‘20 or Rastogi et al '20, until evidence supports a better protocol.

Many factors are known to predispose individuals to higher risk from exposure to SARS-CoV-2, such as age, being male, comorbidities, etc., but inadequate vitamin D is by far the most easily and quickly modifiable risk factor with abundant evidence to support a large effect. Vitamin D is inexpensive and has negligible risk compared to the considerable risk of COVID-19.

Please Act Immediately

5 The following include 4000 IU within their tolerable intakes in official guidelines: NAM (US, Canada), SACN (UK), EFSA (Europe), Endocrine Society (international), Nordic countries, Netherlands, Australia & New Zealand, UAE, and the American Geriatrics Soc. (USA, elderly). No major agency specifies a lower tolerable intake limit. The US NAM said 4000 IU “is likely to pose no risk of adverse health effects to almost all individuals.” See also [Giustina et al ‘20].

Our goal is to change policy and standard of care to save lives and help mitigate the pandemic, not simply to create the longest possible list of names. At this point, we welcome additional signature requests from those likely to help convince decision makers to implement the calls-to-action enumerated in the letter, such as respected professors, medical doctors with demonstrable additional expertise in vitamin D or the treatment of COVID-19, or other notable authorities likely to have relevant influence. If you are such an authority, please fill out this form.
