If you weren’t paying attention to the studies (which weren’t being reported in mainstream media), you wouldn’t know that covid is largely a condition of Vitamin D deficiency. The evidence has been there since May of 2020, but virtually no one is reporting on it, or paying attention. Meanwhile, and the government locked you in your house all year, eliminating your Vitamin D production, in order to fight covid!
This curated playlist of Vitamin D videos tracks our year of research and the scientific basis for using Vitamin D to prevent and cure covid.
Vitamin D, Large scale studies
Low plasma 25(OH) vitamin D level is associated with increased risk of COVID‐19 infection: an Israeli population‐based study (Federation of European Biochemical Societies Journal)
Comparing data across nations, mortality from COVID-19 is clearly higher in some countries than in others
Relative vitamin D status of populations
Vitamin D supplementation could be especially important for older people
Functions
Calcium and phosphate balance
Affecting bone growth and turnover
Low vitamin D status
Associated with increased susceptibility to infectious disease
Notably, upper respiratory tract infections
Treating the lowest levels gives most percentage benefit
Vitamin D and COVID-19
Virus emerged and started its spread in the northern hemisphere at the end of 2019
When levels of 25-hydroxyvitamin D are lowest
COVID-19 mortality was significantly associated with vitamin D status in different populations
Nordic countries, widespread fortification of foods
Italy and Spain, prevalence of vitamin D deficiency, surprisingly common
Black and minority ethnic people
UK, more than four times more likely to die from COVID-19
In COVID
Vitamin D supports production of antimicrobial peptides in the respiratory epithelium
Might help to reduce the inflammatory response
Vitamin D is known to interact angiotensin- converting enzyme 2
SARS-CoV-2 down regulates expression of ACE2
Vitamin D promotes expression of this gene

The circumstantial evidence is very strong
we don’t have randomised controlled trial evidence, but how long do you want to wait in the context of such a crisis?
We know vitamin D is important for musculoskeletal function, so people should be taking it anyway
Vitamin D supplements should normally be given to care home residents unless there is an extremely good reason not to do so.

At best vitamin D deficiency will only be one of many factors involved in determining outcome of COVID-19
but it’s a problem that could be corrected safely and cheaply
there is no downside to speak of, and good reason to think there might be a benefit

The Joint Committee on Health
The Committee heard evidence that Vitamin D deficiency is prevalent across the population and the report recommends that public health measures are established to address that deficiency. These public health measures are preventative in nature and are recommended to reduce the risk of respiratory and other illnesses such as osteoporosis.
1 That daily Vitamin D supplementation of 20-25µg/day should be recommended to the entire adult population as a public health measure,
higher doses recommended for vulnerable groups under medical supervision.
2 That a public health policy, which promotes better knowledge of the benefits of Vitamin D, and which encourages Vitamin D supplementation, should be developed in time for consideration in Budget 2022.
3 That reducing the cost of Vitamin D supplementation, in order to promote its uptake, should be considered.
4 That specific measures need to be put in place for vulnerable groups, and for frontline and healthcare workers,
so that Vitamin D supplementation is administered on an opt-out basis,
and for the duration of this pandemic, people should be offered Vitamin D supplements when presenting at Covid-19 test centres.[+] Show More

10 ng/ml
Data from 440,581 UK Biobank participants
415,903 identified as White European
7,880 Asian
7,602 Black African
1,383 Chinese
6,473 of mixed ancestry
Prevalence of vitamin D deficiency
Asian ancestry
57.2% in winter or spring
50.8% in summer or autumn
Black African ancestry
38.5% in winter and spring
30.8% in summer or autumn
Mixed ancestry
36.5% in winter and spring
22.5% in summer or autumn
Chinese ancestry
33.1% in winter and spring
20.7% in summer or autumn
White European ancestry
17.5% in winter and spring
5.9% in summer or autumn
Participants with higher socioeconomic deprivation
More likely to have 25(OH)D deficiency compared to less deprived participants (P = less than 1 × 10 −300)
This pattern was more apparent among those of White European ancestry
Regular consumption of oily fish was associated with reduced odds of vitamin D deficiency across all ethnicities
Asians are less likely to eat fish or use vitamin D supplements compared to other ethnicities
Outdoor-time in summer was less effective for Black Africans than White Europeans
Other risk factors
Living further north
Indoor employment

Professor Elina Hypponen (SA)
The severity of vitamin D deficiency is concerning
especially with the high rates of COVID-19 infections in Europe and elsewhere in the northern hemisphere this winter
Clinical trials have shown that vitamin D supplements are beneficial in the prevention of respiratory infections and even mortality
Vitamin D is not expensive and the doses which have shown the greatest benefits are those that we can all acquire over the counter from the local pharmacy
Given the COVID-19 pandemic, now is really the time for all who may be affected to take action[+] Show More

Therapy versus best Available Therapy on Intensive Care Unit Admission and Mortality Among Patients Hospitalized for COVID-19: A Pilot Randomized Clinical study" (Spain, Journal of steroid biochemistry and molecular biology)
76 consecutive patients hospitalized with COVID-19 infection
Clinical picture of acute respiratory infection

Positive SARS-CoV-2 PCR
Procedures
All hospitalized patients received as best available therapy
Hydroxychloroquine and azithromycin
Allocated at a 2 calcifediol:1
Oral calcifediol (0.532 mg), or not
Oral calcifediol (0.266 mg) on day 3 and 7
Then weekly until discharge
End points, ICU admission and deaths.
Results
50 patients treated with calcifediol
One required admission to the ICU (2%),
Of 26 untreated patients, 13 required admission (50%)
p less than 0.001
Of the patients treated with calcifediol, none died, and all were discharged, without complications
Of the patients not treated, 2 died
Conclusion
Calcifediol seems to be able to reduce severity of the disease
Larger trials with groups properly matched will be required to show a definitive answer
Rationale, activation of the vitamin D receptor (VDR) signalling pathway
