Niacin is one of the most studied and documented nutrients to support lipid levels already within the normal range, especially high-density lipoprotein cholesterol (HDL-C). Sustained-release niacin, as found in Easy Niacin, has a lesser flushing effect than instant-release niacin. Use of a proprietary, wax-coated technology permits release that is complete in seven to eight hours, the time that is considered ideal for a time-release form of niacin.*
