Amino Acids are an essential component of all metabolic processes and structure in the human body. This formula provides all the essential amino acids to support overall health. Depending on one’s lifestyle, diet choices, impaired metabolism, and genetic differences, individuals may have sub-par levels of certain amino acids. Supplementation can help make up for these losses. NOW® Amino Complex combines whey and soy protein sources to provide a complete amino acid profile and augments this mixture with free-form L-Arginine, L-glutamine, and L-Ornithine and Vitamin B6 to provide improved protein synthesis. This product contains dairy and soy.
