Collagen is the most abundant protein in your body. Collagen has many important functions, including providing your skin with structure, strengthening your bones etc. Amazing Formula Collagen complex is made with Collagen Type I, II and III blends. We source our collagen blend from Premium Quality Hydrolyzed (bovine and chicken) collagen. We only use hydrolyzed collagen, which means the collagen has been broken down, making it easier for you to absorb.
