Niacin, 500 mg, Capsules - Now Foods

Now Foods Niacin — 500 mg of Vitamin B3 (nicotinic acid) in an immediate-release capsule. A high-potency therapeutic dose of regular Niacin for energy metabolism, cardiovascular health, and nervous system support. Recommended for use under doctor's supervision. 100 capsules.

Why you need it

Niacin (Vitamin B3) is one of the most important and well-researched B vitamins — essential for energy metabolism, cardiovascular health, nervous system function, and DNA repair. Regular niacin (nicotinic acid) is the most bioactive and well-researched form, particularly for cardiovascular support. This immediate-release capsule delivers 500 mg of niacin per capsule — a high-potency therapeutic dose at 3,125% DV. Note that regular niacin at this dose commonly causes a temporary skin flushing reaction — a warm, tingling, red flush — which is a normal and harmless physiological response. Taking it with food and consistently every day helps minimise this. If you prefer to avoid flushing entirely, we also stock flush-free niacin options. At this potency, physician supervision is recommended. The 100-capsule size is ideal for those starting out or trialling niacin supplementation.
