SCIENTIFIC REFERENCES ON NIACIN, VITAMIN B3, NAD, etc.
DISCLAIMER: There is no scientific study that says that the replenishment of the coenzyme NAD (Nicotinamide adenine dinucleotide) by any method treats, cures, or prevents any disease, including COVID-19. The human evidence only shows that NAD precursors – B3 vitamins, like Niacin or Niacinamide or Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN) – are safe and effective at replenishing NAD. The effect of that replenishment in humans remains unproven. It is only in animal studies that we consistently see NAD replenishment having a positive effect on physical conditions involving NAD depletion.
