Collagen is an important protein source, providing the nutrients required for the many processes that take place in muscles and cells. Collagen comprises 30% of the body’s protein content and is the ‘glue’ that holds your body together – it’s the fibrous protein found in organs, eyes, muscles, skin, hair, nails, teeth, bones, blood vessels, joints, tendons, cartilage and throughout your entire digestive system. Many other collagen products include a list of ‘flavourants’ which are chemicals, preservatives and other things that don’t have to be disclosed which bring the price down for the manufacturer. The MANKIND GROOM COLLAGEN PEPTIDES range is 96.7% pure hydrolyzed collagen. Factually, this would be 100% pure however we cannot factor out oxygen and hydrogen at 3.3%. In other words, Mankind Groom Collagen is the purest form of collagen powder.
