Here is a link to today's Dr. Mercola article on niacin and melatonin for metabolic health (his articles are deleted after 48 hours). It also addresses how these two supplements can assist with Covid.
You can download it as a PDF to save it before it's gone forever (PDF icon is next to the date at the top of the article). I tried attaching the PDF but it didn't work (operator error, no doubt!).
As well, here is the Web site for Niatonin (niacin and melatonin synergy). It has dosages for preventive, acute or jab-injured and long-haulers.
Sounds interesting. They recommend powdered supplements and the niacin has to be the flush variety. Perhaps it is another alternative for those who can't get access to Ivermectin.
Best of health to all,
