ENDUR-ACIN ER NIACIN 250 mg 100 Tablets

ENDUR-ACIN Extended Release Niacin 250mg — Low-Dose Entry Point for Niacin Therapy

ENDUR-ACIN ER 250mg delivers nicotinic acid (true niacin) in the same clinically studied SmartMatrix™ vegetable wax matrix as the higher-strength versions, at a 250mg starting dose. This lower-strength format serves two important clinical purposes: it provides the ideal titration starting point for patients new to niacin therapy who want to establish tolerance before progressing to higher doses, and it allows flexible multi-tablet dosing protocols where patients can titrate up from 250mg to 500mg or 750mg by adjusting the number of tablets under medical supervision.

ENDUR-ACIN's wax matrix controls niacin release over 4–8 hours, dramatically reducing the prostaglandin-mediated skin flushing that is the main tolerability challenge with immediate-release niacin. Unlike 'flush-free' niacin products (inositol hexanicotinate or niacinamide) which avoid flushing by not releasing free nicotinic acid in clinically meaningful amounts, ENDUR-ACIN delivers genuine nicotinic acid at a controlled rate — maintaining the pharmacological efficacy of true niacin for cardiovascular benefit while improving the tolerability that makes sustained use practical. Family-owned and operated since 1978 in Oregon, Endurance Products has the longest track record of any wax-matrix niacin producer in the supplement industry.
