L-arginine is a semi-essential amino acid involved in multiple areas of human physiology and metabolism.* L-arginine significantly affects endocrine function and helps regulate the release of neurotransmitter chemicals, insulin, glucagon (which has the opposite effect of insulin; i.e., it raises blood sugar), and growth hormone.* However, one of L-arginine's most compelling contributions to human physiology is its role 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, and protection against oxidative damage.*
L-arginine is absorbed and metabolized very quickly in the body, which usually necessitates taking it multiple time during the day. However, sustained-release Perfusia-SR maintains an optimal level of L-arginine over 24 hours with suggested twice-daily use.*
Studies on Perfusia-SR show increased blood flow to the heart muscle and the extremities, maintenance of already normal blood pressure, and improved vascular elasticity.* A recent study demonstrated improvements in blood flow after Perfusia-SR supplementation in individuals who had less than optimum heart health.* In another study, Perfusia-SR was given to 29 healthy volunteers for one week and significant support for a healthy cardiovascular system was observed.*
Take 2 capsules two times daily or as recommended by your health-care practitioner.
