View Certificate of Analysis »

  • Niacinamide vs. Niacin. Compared to other companies that typically use niacin, ProHealth Longevity uses niacinamide because the body doesn’t have to do extra work to convert niacin into niacinamide.
  • Doesn’t Cause Skin Flushing. Plus, high doses of niacinamide don’t cause skin flushing, like high-dose niacin products tend to do.
  • High Dosage. ProHealth Longevity’s Flush-Free Niacinamide contains 600 mg of niacinamide (as nicotinamide) per serving, which is 3,750% of the Daily Value for niacin. Competitors typically contain 500 mg.
  • Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.
  • Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.
A non-flushing form of vitamin B3, niacinamide is an antioxidant and NAD+ precursor that supports DNA repair and sirtuin activation.
