Inadequate nutrition - especially low vitamin D - is not properly recognised by the medical profession.
Welcome to Nutrition Matters by me - Robin Whittle, an electronic technician and computer programmer who is concerned about nutrition in general and in particularly about most MDs having an inadequate understanding of the importance of good, 50ng/ml 125nmol/L, 25-hydroxyvitamin D levels for the immune system.
Please see my sites: https://vitamindstopscovid.info and the older, more extensive, and less organised https://aminotheory.com/cv19/ . I have been on the vitamin D and COVID-19 case since late March 2020, writing to the WHO, MDs etc. and making the websites.
If and when I make a paid membership option, this will not involve special access to anything. It will people can provide practical support which will fund snail-mail postage for printed material about vitamin D, the immune system, COVID-19 and early treatment to MDs, immunologists, virologists and epidemiologists.
In the meantime, tell your friends!
