NOW Niacin 500 mg – High-Potency Flushing Vitamin B3, 100 Veg Capsules

NOW Niacin 500 mg provides high-potency vitamin B3 as nicotinic acid in a convenient vegetable capsule. Each one-capsule serving supplies 500 mg of niacin, which supports normal cellular energy metabolism by helping the body convert carbohydrates, fats, and proteins into usable energy. Important: this is a flushing form of niacin — it may temporarily cause warmth, itching, tingling, or skin redness — and it should be used under a doctor's supervision. If you want a no-flush option instead, see NOW Niacinamide 1000 mg, or compare NOW Flush-Free Niacin 250 mg for a lower-potency flush-free capsule.
