multi collagen powder premium hydrolyzed peptides with organic prebiotic inulin (vanilla) 16 oz/1 lb. 20 amino acids (workout recovery, lean muscle, connective tissue/fibrous protein) tet metabolic research about one-quarter of the total body protein is collagen and it is also the main structural protein of the body. it’s found in connective tissues such as ligaments, cartilages, tendons, bones and several other tissues including the skin. there are over 19 types of collagen fibers spread across the different tissues. collagen as a structural protein has great tensile strength to support our frame and maintain the architecture of organs. due to it toughness, collagen is poorly digested in the gut, thus tet metabolic’s nutritional supplement collagen is partially hydrolyzed (broken down) into peptides. tet metabolic’s collagen peptides are made by boiling cow hides to soften, followed by enzymatic protease digestion, just as it occurs in the gut. collagen peptides facilitate the growth of muscle fibers and muscle mass with exercise. collagen peptides have several positive effects on bones, as they promote bone cell growth, increase bone metabolism, density and strength. collagen makes up ~70% of the skin and provides the skin with its elasticity and tensile strength. collagen peptides support hair and nail growth.
