Collagen is a major structural protein in the human body (found in skin, joints, bones, blood vessels and connective tissues). As we age, collagen naturally breaks down and diminishes over time – leading to the early signs of aging. Youtheory® Marine Collagen is designed to help replenish the body’s supply of this vital protein. This product features a unique fish-sourced collagen that has been specially processed to improve digestibility and absorption into the body. It also includes a blend of essential nutrients & cofactors to promote intensive nourishment. Feel the power of advanced collagen replenishment!.
