Just take vitamin D?

A short post this evening, based on this paper:

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

Lorenz Borsche, Bernd Glauner and Julian von Mendel. Nutrients. 2021; 13(10):3596

I’d analyse the paper further, but the crucial information is in the title (my emboldening). How to achieve 50ng/mL? This paper suggests that:

Without significant sun exposure, achieving a 25(OH)D concentration >50 ng/mL requires vitamin D ingestion of approximately 4,000 IU/day in persons >8 years of age.

I note that supplementation up to approximately 4,000IU per day is within the safe supplementation range according to the US National Institute of Health.

I’ll leave it at that — whether or not to take vitamin D supplements to help protect against covid is a matter for the reader to consider.
