From Manufactured Label:Collagen is a complex structural protein that maintains strength and flexibility throughout the body. Super Collagen is made up of the collagen peptides Type 1 & 3 which support collagen in skin, hair, nails, muscles, tendons, ligaments and bones. Super Collagen is enzymatically hydrolyzed, providing an amino acid ratio with a low molecular weight for maximum bioavailability and utilization by the body. When Super Collagen is taken internally, the body receives the raw materials it needs to supplement the collagen found in all of these areas and may act as a messenger to trigger the synthesis of new collagen fibers. Super Collagen is neutral in taste and is specifically formulated in an easy to take powder form. 7 oz. powder. Manufactured by: Neocell
