Vitamin B3 and heart
For heart support, Vitamin B3 is a supporting ingredient backed by research. Available as nicotinic acid or nicotinamide (niacinamide); both support cellular energy and NAD+ synthesis, but only nicotinic acid improves lipid profiles by raising HDL cholesterol and lowering triglycerides — nicotinamide has zero effect on lipids. Nicotinic acid causes characteristic flushing (redness, warmth) at doses above 30–50 mg, while nicotinamide does not.
How much vitamin b3 do you need
Research points to 25–500 mg as the effective range for vitamin b3. Common in B-complex and standalone formulations; UL 35 mg applies to flushing form only. Lower doses may provide some benefit, but most studies showing clear results used this range.
