Amino acids are the subunits that make up proteins. They are necessary for the function of all cells, for tissue repair, and for the production of enzymes and neurotransmitters.* The body uses 20 amino acids to construct proteins, but nine "essential amino acids" cannot be made by the human body and must be supplied by the diet in order to achieve proper protein synthesis and maintain overall health.*People with limited diets or poor digestion may not get enough essential amino acids from their diet. In contrast to proteins or peptide-bound amino acids, NOW Sports Amino-9 Essentials has all 9 essential amino acids in their superior free-form state and in the proportions recommended by the National Academy of Sciences to optimize protein synthesis and tissue repair for adults age 19 and over.*Dietary ConsiderationsWheat FreeDairy/ Milk FreeGluten FreeKosherSoy FreeEgg FreeShellfish FreeNon-GMOFish FreeTree Nut FreeServing Size:5.6 gServings Per Container:59 Amount Per ServingCalories20L-Leucine918 mgL-Lysine (from L-Lysine Monohydrochloride)888 mgL-Phenylalanine751 mgL-Valine518 mgL-Threonine466 mgL-Isoleucine442 mgL-Methionine432 mgL-Histidine (from L-Histidine Monohydrochloride)319 mgL-Tryptophan117 mgSuggested Use: Mix 2 14 level teaspoons with 8 oz. of juice or your favorite beverage once daily.
