Anthocyanidins are believed to be particularly active in the body and they have been of great interest to scientists for the role they play in supporting collagen. Since collagen is found in high concentrations in capillary walls people in Europe often choose to take anthocyanidins on a regular basis to help maintain the health of their peripheral circulation. Collagen is also responsible for the suppleness and firmness of skin and it has long been recognised that skin health and complexion is influenced to a great degree by dietary factors. We have 3 products containing bilberry; Eyewise® for eye health, Colladeen Original® for capillary and leg health and Colladeen Visage® for skin.
