    Product Overview


    • Dietary Supplement
    • Hypoallergenic
    • Inositol Hexaniacinate - a Safer, Non-Flushing Alternative to Niacin
    • Provides a Higher Amount of Niacin without the Flushing
    • Unlike Time-Release Niacin - Niasafe is Easy on the Liver
    • Supports Peripheral Vascular Circulation
    • Supports Lipid Metabolism

    Niacin has long been used to support good cardiovascular health. It has been proven effective at helping to maintain already normal levels of cholesterol.

    The side effects of high amounts of niacin that may occur range from flushing and itching to liver toxicity and impaired glucose tolerance. Therefore, the need for a safer approach to niacin supplementation resulted in the investigation of niacin esters. One of the most widely studied niacin esters is inositol hexaniacinate (IHN). In numerous trials IHN has been found to be virtually free of the side effects associated with conventional niacin therapy. Pharmacokinetic studies show the IHN molecule is absorbed intact and slowly hydrolyzed in the bloodstream, releasing free niacin and inositol and having a diminished impact on the liver. Maximum serum levels are reached approximately 10 hours after ingestion, thus allowing for a more delayed release of niacin that reduces the risk of flushing.

    A review of the literature reveals numerous positive studies on the use of IHN to support good circulatory health, particularly the support of vascular circulation to the extremities.

    Expensive but ...

    Posted by iHerb Customer on Mar 18, 2017 | Verified Purchase

    I began using Niasafe around a year and a half ago and since then have tried other less expensive products but have always returned to Niasafe. It's the only only which seems to agree with my system and give me the energy I need so I have continued buying it at iHerb, where it is at least affordable. Thank you iHerb! Pleaqse DO keep it in your product line.

    Thanks for your feedback!

    Don't get any red flushes

    Posted by OssieA on Oct 16, 2011 | Verified Purchase

    Ordinary niacin gave me red rashes if I didn't eat enough when taking. This Niasafe doesn't do that.

    Thanks for your feedback!
