What It Actually Is
L-Arginine is an amino acid the body uses as a building block to produce nitric oxide, a compound that helps relax and widen blood vessels.
What Research Generally Shows
L-Arginine has a reasonable research base tied to circulation and, in some studies, mild support for erectile function, though results vary by dose and study population.
On The Dose
Clinical studies on L-arginine for circulation often use 3-6 grams daily — thousands of times more than an 82mg total blend split nine ways could contain.
