Support Heart & Cholesterol with Targeted Niacin

About this item

Endurance Products Niacin 500mg is a crystalline vitamin B-3 supplement available in India through crowcrowcrow, with a proprietary vegetable-based wax matrix that slows delivery for sustained release.

It dissolves gradually, releasing niacin over about an hour, aiding in heart health and cholesterol balance. Clinical benefits are supported by targeted niacin forms, unlike flush-free variants.

Manufactured in the USA at an FDA-registered facility, this vegan, gluten-free supplement meets strict GMP standards. It is free of common allergens and packaged in a family-owned operation since 1978, ensuring quality and safety.

Key Features

  • EACH SERVING CONTAINS 500mg of immediate-release nicotinic acid (crystalline niacin, vitamin B-3) with our proprietary vegetable-based wax matrix tablet core that slows delivery.
  • TABLETS DISSOLVE MORE SLOWLY than regular formulas, gradually releasing nicotinic acid in about an hour instead of all at once.
  • HEART HEALTH AND CHOLESTEROL BALANCE.* Nicotinic acid is the only form of niacin with targeted benefits. Other "flush free" forms of niacin have not been clinically shown to benefit heart health.*
  • FREE OF COMMON ALLERGENS: Vegan/Vegetarian safe. No milk, egg, fish, shellfish, tree nuts, peanuts, wheat, corn, yeast, or soy. Gluten-free. No salt, sugar, starch, artificial flavorings, or preservatives.
  • MEETS STRICT GOOD MANUFACTURING PRACTICES: Manufactured and packaged in the Pacific Northwest, USA at an FDA registered facility. Family-owned and operated since 1978.

Why choose this product
