NOW Double Strength Flush-Free Niacin delivers 500 mg of niacin, or vitamin B3, in each convenient vegetable capsule. The formula uses inositol hexanicotinate, a stable form composed of niacin linked with inositol. It is gradually broken down to provide niacin activity without the characteristic flushing sensation commonly associated with traditional high-dose niacin supplements.

Niacin is an essential B-complex vitamin that contributes to normal energy metabolism and helps support overall nutritional wellness. With twice the niacin found in NOW's regular-strength 250 mg formula, this double-strength supplement provides a convenient once-daily option for adults seeking concentrated vitamin B3 support.

Each bottle contains 90 vegetable capsules and is suitable for vegan and vegetarian lifestyles. The formula is Non-GMO, Kosher, dairy-free, egg-free, nut-free, soy-free, and made without gluten-containing ingredients. It is manufactured in a GMP-certified facility by NOW Foods, a family-owned natural-products company established in 1968. This quality-focused, flush-free niacin supplement is designed for adults who want to add high-potency vitamin B3 to a health-conscious daily routine. Natural color variation may occur.
