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 Collagen Powder is designed to help counteract age-related collagen loss.* Supplying 20 mg of hydrolyzed collagen per serving, this convenient and easy-to-use product helps replenish essential beauty proteins, while delivering powerful health benefits.* This formula is enhanced with vitamin C to aid internal collagen production and Biotin to support health and beauty factors.
