Maintaining the natural, healthy functions of the vascular endothelium is dependent upon an adequate supply of L-arginine being available to these cells. The conversion of L-arginine to nitric oxide is responsible for these functions by making the endothelial cells more resistant to oxidative damage and adhesion by otherwise harmful substances. This is critical to maintaining good vascular health, heart health, reproductive health, and protection against oxidative damage.

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. One study demonstrated improvements in blood flow after Perfusia-SR supplementation in individuals with less than optimum heart health. In another study, Perfusia-SR was given to 29 healthy volunteers for one week and significant support of their already normal cardiovascular health was observed.

L-arginine is absorbed and metabolized by the body very quickly, which usually necessitates taking it frequently throughout the day. Sustained-release Perfusia-SR, however, maintains an optimal level of L-arginine over 24 hours with suggested twice-daily use.
