Perfusia-SR by Thorne Research is a sustained-release formulation of the amino acid L-arginine. Supplementation with L-arginine improves the production of nitric oxide by vascular endothelial cells, which increases vasodilation while inhibiting platelet and monocyte adhesiveness, resulting, for example, in enhanced cardiovascular health and erectile function.

This unique, sustained-release product provides for improved long-term blood levels with twice daily dosing.
