L-Arginine

Compare by declared L-arginine; price is normalized to the same 1 g.

💡 What to know

What we compare

This category compares the label-declared amount of L-arginine itself. L-arginine HCl is shown as a form; an HCl-only amount is not converted to free L-arginine unless the label provides that value. AAKG and multi-ingredient blends are kept outside this comparison. Price is normalized to 1 g L-arginine.

Benefits

L-arginine is incorporated into proteins and is a biochemical precursor for nitric oxide, creatine, and polyamines. It also participates in the urea cycle, which helps bind and eliminate ammonia.
