Collagen is the most abundant protein in the body, making up about 30-35% of the total protein. Collagen is in every tissue of the body and is the connective tissue in structures such as skin, hair, nails, bones, lungs, heart and liver. It is often referred to as the glue that holds the body together. Collagen contains glycine, proline, and hydroxyproline, the three amino acids the body uses to manufacture its own collagen.

Why add extra collagen to your diet?

Traditionally, collagen used to make its way into people's diets through foods like bone broths, slow-cooked organ meats, kidney pies, baked beef hearts, whole crustaceans, and whole-fish soups and stews. However, unless a person is routinely eating these types of meals, chances are the body is barely getting any naturally occurring collagen protein at all.
