Clear Collagen consists of 91% hydrolyzed collagen, which means that a refreshing drink from one serving (22g) of drink powder supplements your body with 20g of collagen per day. Collagen is a critical protein found in our connective tissues and skin. Our bodies are capable of producing collagen, but as we age, it becomes increasingly important to supplement it with collagen derived from external sources. High-quality collagen products contribute to the rejuvenation and health of your skin.
