L-Arginine

   L-Arginine - Sustained Release (formerly Perfusia-SR) DetailsThere has been significant research on the cardiovascular benefits of L-arginine – the primary ingredient in L-Arginine - Sustained Release – for supporting vascular health and blood flow.* One of L-arginine's most important roles is as a biological precursor of nitric oxide.* The vascular endothelium (the lining of the arteries) creates nitric oxide from L-arginine, resulting primarily in blood vessel relaxation.* This property is important to maintaining good vascular health, heart health, reproductive health, wound healing, and protection against oxidative damage.* L-arginine also promotes increased work capacity during exercise, supports lean muscle mass, and helps erections occur in the normal course of intimacy.* L-Arginine - Sustained Release  is provided in a sustained-release formula to maintain an optimal level of L-arginine over 24 hours with suggested twice-daily use.*L-arginine is a semi-essential amino ac
