Sustained Nitric Oxide Support for Circulation, Heart & Performance

L-Arginine is a semi-essential amino acid and the primary precursor to nitric oxide, a molecule your body uses to relax blood vessels and support healthy circulation.

L-Arginine Sustained Release delivers 1 gram per serving in a time-release formula designed to maintain steady L-arginine levels throughout the day. This helps support vascular health, blood flow, heart function, exercise performance, and reproductive health—without the peaks and crashes of standard capsules.

Nitric oxide is produced by the vascular endothelium (the lining of your blood vessels) from L-arginine. When nitric oxide levels are supported, blood vessels can relax and widen, allowing more efficient delivery of oxygen and nutrients to tissues and organs.*
