Vitamin D power for immunity and Covid-19 by Marc Sorenson EdD
Vitamin D power may be exactly what we need to defeat covid-19 and other maladies. This is a according to a press release and new research from the Vitamin D Society of Canada (VDSC). The release is entitled Strengthen Your Immune System to fight COVID-19 – World Vitamin D Day. It indicates optimal vitamin D levels may equal social distancing and masks for reducing covid-19 this winter. VDSC Executive Director Perry Holman states, “Increasing your daily intake of vitamin D is an action you can take immediately to safeguard your health until a COVID-19 vaccine becomes available. Many people have deficient or insufficient vitamin D levels. As we celebrate the 11th anniversary of World Vitamin D Day on Nov. 2, please evaluate your vitamin D intake and increase it to COVID-19 fighting levels.”
The press release then discusses how to increase vitamin D.
Adults should take 4,000 IU per day of vitamin D. Thus, Dr. Anthony Fauci, a leading infectious disease expert, takes 6,000 IU per day.
Enjoy natural sunlight when the UV index reaches three and your shadow is shorter than you are. Never sunburn. (This, in my opinion, is the most important and natural way to produce vitamin D power.)
Consider artificial UVB exposure when natural sunlight is weak or not available and your skin type can receive UV exposure without burning.
Increase your food intake of fatty fish such as salmon.
Take a vitamin D3 supplement to make up the balance when sun exposure is not available. UVB from sunlight or a sunlamp is what makes vitamin D naturally in your skin.
New research backs up the press release and lends credence to the focus of the article. The research below is verbatim from the press release and shows the efficacy of vitamin D .
In a US based study of over 190,000 people, researchers found that those people with a deficient vitamin D blood level (below 50 nmol/L or 20 mg/ml) had a 54% higher COVID-19 positivity rate compared with people who had adequate vitamin D levels (75 nmol/L or 30 ng/ml). (Kaufman 2020)
In a study published in the Journal of the American Medical Association (JAMA), researchers at the University of Chicago found that patients who had deficient vitamin D blood level (less than 50 nmol/L or 20 ng/ml) had a 77% greater risk of testing positive for COVID-19 vs patients who had a sufficient vitamin D status. (Meltzer 2020)
A small, randomized controlled trial (RCT) study in Spain found that COVID-19 patients treated with vitamin D were less likely to be admitted to the intensive care unit (ICU) and less likely to die from COVID-19. The study found that 50% of the patients not receiving vitamin D were admitted to the ICU compared to 2% of the patients receiving vitamin D. Two out of 26 patients who did not receive vitamin D died while none of the 50 vitamin D treated patients died. Some hospitals in Spain are now moving their COVID-19 patients out in the sun to increase their vitamin D. (Castillo 2020)
An Israeli population-based study of 7,807 individuals found that people with vitamin D levels greater than 75 nmol/L or 30 ng/ml were 50% less likely to contract COVID-19 and 95% less likely to suffer hospital stays. (Merzon 2020).
In conclusion, the press release from the vitamin D Society holds the key to preventing Covid-19.
Keep sunning and optimize your vitamin D power!
