L-arginine is a conditionally essential amino acid, meaning that while your body can make it, it becomes necessary to get it in through diet or supplementation under certain circumstances or for certain physical conditions. L-arginine, like other amino acids, is a building block of protein, which helps to promote muscle and tissue healing, helps to support a healthy immune system, and benefits cellular metabolism.

One of L-arginine’s unique functions is that it is necessary for the production of nitric oxide. Nitric oxide is essential to the regulation of blood blow in the body. By supporting nitic oxide levels, L-arginine can support cardiovascular health, benefit healthy blood pressure, and optimize blood flow to the extremities.

Thorne’s L-Arginine – Sustained Release combines L-arginine with our Time-Sorb® complex to help maintain an optimal levels of L-arginine over 24 hours with suggested use.
