Collagen is a natural protein that is produced by your body, which is important to keep your bones, skin, joints, nails, and hair healthy. Among the many types of collagen offered, Marine collagen is the most effective, environmentally sustainable source of collagen. It is made with 100% wild-caught fish from certified, sustainably managed fisheries and formulated with vitamin C, biotin, and hyaluronic acid. The collagen protein is removed from the fish and broken down into smaller units of protein or collagen peptides, which offers high absorption.
