What is Collagen? Collagen is a natural skeletal protein accounting for nearly 80% of the bodys skin, muscles & connective tissue. Depletion of collagen in the skin is thought to be the main reason for the visible signs of ageing.

What Does Collagen Do? May help to maintain healthy hair, skin & nails. It is thought that from the age of 25, your body loses collagen at a rate of 1.5% per annum, so by the age of 35, your body will have lost 15% & by 45, 30%. This is when you really start to notice a change in your skins elasticity & texture. Proper collagen balance in the body is therefore highly desirable. Collagen naturally contains glucosamine & chondroitin which may help to support healthy joints by attracting fluid back into the joint space to cushion the bone & by rebuilding cartilage.
