Product Overview

L-Arginine is a popular amino acid for its amazing nitrogen retention ability.* Nitrogen as you are all aware is one of the key elements in muscle protein synthesis. Some plants can absorb nitrogen, but we mammals have to make do with the stuff we make ourselves. Arginine is mostly present in protanines and histones, two proteins commonly associated with nucleic acids (like DNA and RNA).
