Does Vitamin D Protect Against COVID-19? – FactCheck.org. Watch out for High Fructose!

COVID-19 Update 83 with Roger Seheult, MD of https://www.medcram.com Oxidative stress may play a key role in the severity of COVID-19 infection. A variety of studies have demonstrated how high sugar intake (and fructose in particular – such as high fructose corn syrup) contributes not only to oxidative stress but to the inactivation of a usable form of vitamin D as well. Join Dr. Seheult for illustrations of how these pathways work.

Does vitamin D help protect against COVID-19?A: Some scientists have hypothesized vitamin D might be helpful, but there is no direct evidence that vitamin D can prevent COVID-19 or lessen disease severity. Nevertheless, it should be part of a healthy lifestyle.

Very Low activated (by the liver and kidneys) vitamin D occurring in some local populations does cause many problems for the body and the immune system. Since activated vitamin D is a known moderator of inflammation this could a red flag for severe Covid19 cytokine storm. From from the video above, high fructose can block activation of Vitamin D, but if you eat garlic and onion?? Wait for the end of the video 🙂

“A new global collaborative study has confirmed that vitamin D supplementation can help protect against acute respiratory infections. The study, a participant data meta-analysis of 25 randomized controlled trials including more than 11,000 participants, has been published online in The BMJ.

“Most people understand that vitamin D is critical for bone and muscle health,” said Carlos Camargo of the Department of Emergency Medicine at Massachusetts General Hospital “Our analysis has also found that it helps the body fight acute respiratory infection, which is responsible for millions of deaths globally each year…

“Meta-analyses of these trials, which aggregate data from several studies that may have different designs or participant qualifications, also had conflicting results. To resolve these discrepancies, the research team — led by Adrian Martineau from Queen Mary University of London — conducted an individual participant data meta-analysis of trials in more than a dozen countries, including the U.S., Canada, and the U.K.

“The investigators found that daily or weekly supplementation had the greatest benefit for individuals with the most significant vitamin D deficiency (blood levels below 10 mg/dl) — cutting their risk of respiratory infection in half — and that all participants experienced some beneficial effects from regular vitamin D supplementation.

“Administering occasional high doses of vitamin D did not produce significant benefits.
