Fish Collagen is a key building block of the human body and is used in the formation and support of bones, cartilage, ligaments, tendons and other key strength-giving components. Collagen contains many amino acids - these are the building-blocks of proteins, and have a central role in biochemistry and nutrition. Collagen is, by far, the primary structural protein in the body, contributing as much as 30% of the body’s entire protein content. It is central to the structure of our skin, joints and blood vessels, since we cannot create these tissues without Collagen. One cannot consider the health of our skin, bones, blood vessels, joints or connective tissue without recognizing the dominant role that Collagen protein plays. It is for this reason that Collagen is added to so many beauty products, from moisturizers and anti-aging creams to shampoos and conditioners.
