Vitamin D and COVID-19 by Daniel J Murphy DC, DABCO

Key Points


1. “Vitamin D is a lipid-soluble vitamin that is essential for maintaining good health, growth, and strong bones.”

2. Vitamin D can be produced in the skin with the help of exposure to sunlight.

3. Most foods naturally contain very little vitamin D.

4. Hypovitaminosis D is associated with cardiovascular disease, type-2 diabetes, metabolic syndrome, cancer, and increased death rates.

5. “Advanced age and high body-fat mass leads to an increased risk of deficiency of vitamin D.”

6. “A mild vitamin D deficiency does not cause symptoms, but may cause weakness, aches, and pain in general.”

7. “Vitamin D has been recognized as essential to the skeletal system and plays a major role in monitoring the immune system, perhaps including immune reactions to viral infection.”

8. Low vitamin D is associated with increased risks of influenza and respiratory tract infection.

9. “The severity of influenza and respiratory-tract infections may be increased by vitamin D insufficiency.”

10. Vitamin D deficiency predisposes one to infections of the viral respiratory tract.

11. Vitamin D can balance and control immunity and oxidative reactions against COVID-19 infection.

12. “On survival analysis, extremely vitamin D-deficient patients had a 50% chance of death after 10 days of hospitalization, whereas those with sufficient vitamin D had a 5% risk of death.”

13. “Correlational and cross-sectional observational studies performed in various parts of the world have shown that vitamin D-deficient areas have a higher prevalence of COVID-19 patients.”

14. There is a higher prevalence of mortality, and critical cases of COVID-19 are more common among vitamin D-deficient patients.

15. Hospitalization of COVID-19 patients was associated with vitamin D deficiency by 77%.

16. COVID-19 disease severity is associated with vitamin D deficiency by 95%.

17. Mortality is significantly more common among severely vitamin D-deficient patients.

18. “The rate of COVID-19 was higher in a vitamin D-deficient group than a vitamin D-sufficient group.”

19. “Vitamin D can adequately modulate and regulate the immune and oxidative response to infection with COVID-19.”

20. “Blood vitamin D status can determine the risk of being infected with COVID-19, seriousness of COVID-19, and mortality from COVID-19.”

21. “Maintaining appropriate levels of vitamin D through supplementation or natural methods, e.g., sunlight on the skin, is recommended for the public to be able to cope with the pandemic.”

22. "Compelling evidence indicates vitamin D deficiency is the "seasonal stimulus" responsible for flu outbreaks."

23. "Physiological doses (800-2,000 IU/day) of vitamin D prevent viral infections and Vitamin D is the 'antibotic vitamin' due primarily to its robust effects on innate immunity"

24. "Double-blind, randomized, placebo-controlled trial: 104 women given vitamin D were 3 times less likely to report cold and flu like symptoms. "A low does (800 IU/day) not only reduced incidence, it abolished the seasonality of reported colds and flu. A higher does (2,000 IU/day), given during the last year of their trial, virtually eradicated all reports of cold and flu"

25. "Vitamin D deficiency predisposes children to respiratory infections, and an interventional study showed vitamin D reduces incidence."
