L-Arginine Sustained Release (SR) is an advanced dietary supplement designed for adults interested in overall cardiovascular health, including maintaining healthy blood pressure in the normal range.

Featuring the amino acid L-Arginine in a unique vegetable-based wax matrix that releases L-Arginine gradually. An optimal blood level of L-Arginine is critical for vascular health. Your endothelium – the layer of cells that line your blood vessels – relies on this amino acid for a healthy production of nitric oxide. In turn, nitric oxide plays a key role in vascular health, including promoting blood vessel relaxation and optimal blood flow.*

Adults interested in overall health can benefit from L-Arginine SR as well.
