Formulation Notes

Contains no artificial colors, flavors or preservatives; no wheat, gluten, milk, eggs, peanuts, tree nuts, soy, crustacean shellfish or fish.

Niacin has long been a popular supplement used for healthy cholesterol support, but many users often complain about the “niacin flush” that accompanies its use. Our No-Flush Niacin, also knowns as inositol hexanicotinate, is a form of niacin that provides all of the same benefits as traditional niacin without the flush. This is possible because the body metabolizes inositol hexanicotinate slower than traditional niacin, not reaching full serum levels for nearly 10 hours.
