Collagen
Collagen is a group of proteins that is sometimes referred to as 'the glue that holds our bodies together'. It is a major component of connective tissue - the stuff that helps to hold our joints, bones, cartilage and tendons together. Along with elastin it's also a crucial component of skin, lung tissue and blood vessels, helping to keep each of these important tissues functioning normally.
Collagen Depletion
Depletion of collagen in the skin leads to the formation of wrinkles and the appearance of ageing, which is why you've probably heard of collagen in relation to anti-aging products. Depletion of collagen in connective tissue, which often occurs naturally as a result of age, can contribute to such conditions as arthritis and musculo-skeletal injuries due to a lack of support for the joints. Holland & Barrett stocks a number of collagen supplements, to help support your body's natural stores.
