Collagen is the most abundant protein in the human body, found in the bones, muscles, skin, and tendons. Collagen helps provide structure to many parts of the body, most significantly the skin and joints. Improves the elasticity and strength of skin. Supports good joint health. Important for bone density and muscle repair. Hydrolysis breaks down the collagen in peptides for better bioavailability. These collagen peptides are more easy to digest, absorb, and utilize.
