What Is Niacinamide?

Also known as nicotinamide, niacinamide is a water-soluble B vitamin that provides all the advantages of niacin without the uncomfortable flushing sensation. After ingestion, it is readily converted into cofactors that drive energy production at the cellular level. This makes it a popular choice for those who want high-dose vitamin B-3 without side effects.

Niacin vs. Niacinamide: Which Form Is Right for You?

Vitamin B-3 comes in two primary forms: nicotinic acid (niacin) and niacinamide. The key difference is the flushing effect. Niacin causes a temporary but harmless flush—redness, tingling, and warmth—due to vasodilation. Niacinamide, being a no-flush form, is ideal for daily supplementation, especially if you have sensitive skin or dislike the flush. Both support energy production, but niacinamide offers a gentler profile.
