On “Resources For Novel Coronavirus Covid-19”

…on healthcare professionals. A 1000 admissions a day might be impossible to handle, but 100 admissions stretched out over 10 days is much more manageable. This is something everyone can help with. Also, take a lot of Vitamin D, it helps with handling the Covid19 and other respiratory tract infections (both viral and bacterial). 1 0 link 1 link to this video…

On “Vitamin D Insufficiency is Prevalent in Severe Covid-19”

This systematic meta-analysis paper1 may be more convincing. The popular youtube COVID-commentating Dr. John Campbell did a review of it about a month ago2 and has some good comments on the meaningful statistical power and experiment design. The overall takeaway is this: in people with Vitamin D deficiency (which is very, very common), continuous daily supplementation can lead to up to a 70% reduction in contracted viral respiratory infections. It has a smaller effect the less deficient you are, and is not associated with any adverse effects. 1 - link 2 - link to this video
