NOW Foods Flush-Free Niacin 250 mg provides inositol hexanicotinate — a form of niacin that delivers the cardiovascular and lipid-balancing benefits of niacin without the uncomfortable flushing, tingling, and redness that standard nicotinic acid causes. Niacin (vitamin B3) at therapeutic doses is one of the most effective natural agents for raising HDL (good) cholesterol, lowering triglycerides, and shifting LDL particle size toward the larger, less atherogenic type. The inositol hexanicotinate form releases niacin more slowly, dramatically reducing the prostaglandin-mediated skin flush response while maintaining niacin activity. Each capsule provides 250 mg — suitable as a daily maintenance dose or as part of a stepped niacin protocol. Manufactured in NOW's GMP-certified facility with potency verification. A well-tolerated option for cardiovascular and lipid support.
