Niacinamide
Also called Niacinamide / Nicotinamide
Niacinamide is the flush-free form of B3. It still supports NAD+ synthesis and is well studied for skin health and acne. It does not share the lipid-modifying effects of nicotinic acid, so it is not a substitute for prescription niacin therapy. For general NAD+ and skin support it is the safer and more tolerable choice.

How to take Niacinamide
A typical dose of Vitamin B3 (Niacin): 14–16 mg RDA; 500–2,000 mg for lipid effects under medical supervision. Best timing: With meals; take lipid-lowering doses at night. The form you choose mainly affects absorption and how easily it sits with your stomach, not the overall dose.
