Niacin
TL;DR
Niacin (vitamin B3) exists as nicotinic acid, niacinamide, and nicotinamide riboside (NR). Nicotinic acid uniquely causes vasodilatory "flush" and is the most effective natural agent for raising HDL cholesterol.
Overview
Niacin (vitamin B3) exists as nicotinic acid, niacinamide, and nicotinamide riboside (NR). Nicotinic acid uniquely causes vasodilatory "flush" and is the most effective natural agent for raising HDL cholesterol. All forms serve as precursors to NAD+/NADH, essential cofactors for 400+ enzymatic reactions.

Interactions
enhances. Niacin raises HDL and lowers LDL/triglycerides via different pathway than statins; AIM-HIGH trial raised concerns about combination for additional cardiovascular risk reduction
synergistic. Aspirin (325mg) taken 30 min before niacin significantly reduces prostaglandin-mediated flushing by inhibiting COX enzymes
competes. Both niacin and alcohol are hepatotoxic at high doses; combination increases liver damage risk and worsens niacin-induced flushing
enhances. Niacin has mild vasodilatory and hypotensive effects; may enhance blood pressure-lowering medications, especially during flushing episodes
