Overview of how niacin and its metabolites like NAD, NADP, NADPH play a key role in cellular signaling, apoptosis, balancing intestinal flora and gene expression. Without external supply of supply of niacin, the genome becomes unstable via the antioxidant system no longer functioning efficiently, which ultimately leads to cell death.
The GPR109A receptor and its agonists (niacin and butyrate) have anti-inflammatory actions in the skin, gut and retina. For Parkinson's disease, niacin supplementation may have 3 benefits: lower inflammation via GPR109A-related mechanisms, increase dopamine production in brain by supplying NADPH and boosting mitochondrial functions by increasing the NAD/NADH ratio.
Most "niacin" products are niacinamide. If you want the form discussed in this research, look for nicotinic acid specifically.
