I watched a video recently where the doctor was blaming Covid and other infections on the lack of Vitamin D, and also on weight.
I forget the number, but obviously darker skinned people can’t take in as much Vitamin D from the sun and need to have supplements. Except most people don’t - so they are even more lacking than whites.
Totally true.
One example given in a video I watched (wish I had the specific link) - UK had a rash of doctors getting COVID - I think something like 25 died in a cluster. All but 3 had dark skin (African, etc.). Doses of cholecalciferal were quickly & specifically made available to doctors in the UK and there were no more deaths. In nature, by far the major form of vitamin D that nurtures the body is cholecalciferol. Some patients in ICU with COVID have been given doses of cholecalciferol in an attempt to help them.
On youtube, go to Ivor Cummins channel - he has a bunch of videos on the links between low Vit D/COVID & why some people are low on D - skin color is a big factor, so is latitude. Your risk of a severe case of COVID, if not death, goes up if you have low Vit D levels.
