L-arginine, an amino acid, is a precursor to nitric oxide which keeps blood vessels dilated and flexible and blood freely moving throughout your body.

L-Citrulline (another amino acid) is frequently combined with l-arginine to enhance its effectiveness. It enters the kidney, vascular endothelium and other tissues, and is converted into arginine. Plasma and tissue levels of arginine increase, which is necessary for the production of nitric oxide and relaxation of blood vessels. An additional benefit of supplemental citrulline is that it helps eliminate ammonia, a highly toxic substance, from the liver.


There’s a lot of information online about these two nutrients. Here’s a website that provides a good overview of cardiovascular and other benefits:
