Both niacin and melatonin play important roles in our metabolic health, and some scientists and doctors believe that they also have important roles in fighting Covid-19. Dr. Mercola analyzes the this water-soluble vitamin and hormone in his article Niacin + Melatonin Support Metabolic Health.
He also explores some interesting niacin research from Dmitry Kats, PhD, who published a scientific paper in late December 2020 on niacin and whether it plays a crucial role in the disease process, including Covid-19. Dr. Kats, who is not a medical doctor, has also developed a niacin plus melatonin protocol called the Niatonin Protcol.
