One of the best ways to support your immunity during the COVID pandemic is to make sure you’re getting enough vitamin D. Experts maintain that 30ng/ml on the blood test for measuring vitamin D is the minimum required for health, while 50-60 ng/ml is often considered optimal.
More than 200 leading authorities on vitamin D and other health professionals recently signed an open letter on the internet addressed to “all governments, public health officials, doctors, and healthcare workers,” that called for greater use of vitamin D in the fight against COVID-19.
Noting that “Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths” the letter calls for immediate widespread increased vitamin D intakes to achieve at least 30 ng/mL (75 nmol/L) including hospitalized COVID-19 patients.
The letter cites vitamin D’s particular relevance to COVID:
“Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence shows that:
Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
Intervention studies (including randomized controlled trials) indicate that vitamin D can be a very effective treatment.
Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
Causal inference modeling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.
The letter goes on to say that most people don’t get enough vitamin D, and that current evidence suggests the possibility that the pandemic is being sustained “in large part through infection of those with low vitamin D.” It also notes that deaths appear to have been concentrated in people who are deficient in the vitamin.
The letter calls for more research but says, “Even without more data, the preponderance of evidence indicates that increased vitamin D would help reduce infections, hospitalizations, ICU admissions, & deaths.”
It notes that 6200 IU (155 mcg) of supplemental vitamin D is required for 97.5% of people to reach 30ng/ml. It has been our experience at Beyond Health that most people need 5,000 IU per day or more to reach optimal levels and maintain them. Periodic testing is advised to see if you need to take more or can make do with less. Since vitamin D is available from the sun, full sun exposure will reduce your need for supplementation.
Beyond Health Vitamin D3 Formula offers vitamin D in 5,000 IU capsules together with correct amounts of synergists vitamin A and K2 and mixed tocotrienols, and d-alpha tocopherol for antioxidant protection.
