02/01/22 video: Dr. Mark Hyman: America’s ‘Toxic Diet’ to Blame for COVID Deaths. Poor diet accounted for 63% of COVID hospitalizations in the U.S., Dr. Mark Hyman, founder of the Cleveland Clinic Center for Functional Medicine ... Hyman also cited a study that found people with a vitamin D level over 50 have close to a zero chance of dying from COVID. “There’s no zero from any other drug or vaccine,” Hyman said. “Why don’t we have a vitamin D mandate?” he asked. “It should be given out free to everyone. It’s super cheap and very safe.” ...Hyman reveals two simple questions everyone should ask when it comes to getting their health on track.

Dec 4, 2021. Vitamin D: Government Should Have Promoted to Combat Pandemic. Medical evidence strongly justifies a proactive approach for using vitamin D
COVID-19 mortality risk correlates inversely with vitamin D3 status, and a mortality rate close to zero could theoretically be achieved at 50 ng/ml 25(OH)D3: Results of a systematic review and meta-analysis "Regression suggested a theoretical point of zero mortality at approximately 50 ng/ml D3. Conclusions The two datasets provide strong evidence that low D3 is a predictor rather than a side effect of the infection. Despite ongoing vaccinations, we recommend raising serum 25(OH)D levels to above 50 ng/ml to prevent or mitigate new outbreaks due to escape mutations or decreasing antibody activity."
August 28, 2021 Vitamin D and COVID-19. Talk at the Ancestral Health Symposium

One study involving nearly 8,300 adults enrolled in the UK Biobank study found that those who took vitamin D regularly (daily or weekly) were 34 percent less likely to develop COVID-19 compared to those who did not take vitamin D. This effect was exclusive to supplementation with vitamin D, not other supplements, suggesting a link to vitamin D specifically. Other studies have shown that... COVID-19 patients who had higher vitamin D levels were 20 times less likely to have a critical outcome versus a mild one, and 8 times less likely to have a severe outcome versus a mild one. ...Among patients with COVID-19, 98.9 percent of those with vitamin D deficiency died; 88 percent of those with vitamin D insufficiency died; and just 4 percent of those with sufficiency died, even after adjusting for age, gender, and comorbidities.

https://sci-hub.se/10.1007/s10067-015-2970-6 The patients were 21 girls and 58 boys, average age 5.8 years. Their average 25OHD levels were 9.2ng/ml, while age-matched controls averaged 23.3ng/ml. In the patients who developed coronary artery abnormalities, the average 25OHD level was 4.9ng/ml.
Dr. Cole presents data supporting his strong recommendation that everyone take a Vitamin D and magnesium supplements during winter months so that your immune system functions at peak levels.

Over 200 Scientists & Doctors Call For Increased Vitamin D Use To Combat COVID-19. Scientific evidence indicates vitamin D reduces infections & deaths. 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 and the Immune System By Cynthia Aranow, MD, Investigator
Video: Dr. Roger Seheult from MedCram on COVID-19 Vaccines, Vitamin D, and Heat Hydrotherapy. Mar 3, 2021
Text by Dr. Roger Seheult, the co-creator of MedCram "Vitamin D regulates immune function and plays an important role in preventing respiratory tract infections. It activates the innate immune system, eliciting an early antiviral response. The vitamin binds to receptors on neutrophils, macrophages, and natural killer cells and stimulates them to produce microbial peptides that exhibit antiviral activity. Vitamin D also inhibits the production of proinflammatory cytokines, which can play a role in a cytokine storm – a serious complication of COVID-19. ... A recent study found that regular intake of supplemental vitamin D increases circulating levels of the vitamin and reduces the risk of developing COVID-19 by 34 percent. Vitamin D production in the skin diminishes with age and low sunlight exposure (due to latitude, clothing, or sunscreen), so supplementation is probably the best route for achieving optimal vitamin D status.

Study: Vitamin D deficiency found in over 80% of COVID-19 patients Oct, 2020. By Kiersten Willis, The Atlanta Journal-Constitution. COVID-19 patients at a hospital in Spain were overwhelmingly found to be deficient in vitamin D, according to a new study.
Researchers discovered 80% of 216 COVID-19 patients at the Hospital Universitario Marqués de Valdecilla had a vitamin D deficiency. Men had lower levels of vitamin D than women and COVID-19 patients with lower levels of vitamin D had increased serum levels of inflammatory markers such as ferritin, a blood protein containing iron, and D-dimer, a protein fragment made when a blood clot dissolves in the body. The latter is usually elevated in COVID-19 patients, according to a July study published in the “Journal of Intensive Care.”

Calcifediol is a prehormone that is produced in the liver by hydroxylation of vitamin D₃ by the enzyme cholecalciferol 25-hydroxylase. … Calcifediol [25(OH)D3] treatment... Adjusted results showed a reduced mortality for more of 60%... Higher baseline 25(OH)D levels were significantly associated with decreased mortality (RR 0.40 [95% CI 0.24;0.67]). Age and obesity were also predictors of mortality.
