Not everyone is convinced by the claims of the collagen water industry, mind you. Dietitian Sian Porter points out that when we consume collagen-enriched products, ‘collagen would be broken down in the body like other proteins and used for growth, repair, renewal, energy — whatever your body needs it for. You have no control really where the body “puts things”, so collagen for skin does not mean it will be used for skin.’ Still, one study in the Journal of Cosmetic Dermatology released last year showed an improvement in the skin in women who consumed a collagen peptide drink every day for eight weeks. Plus, of course, merely drinking more water will help. And it’s easy to knock back bottles of the Oasis-like Bella Berry, for instance, which comes in superfruit (pomegranate, blueberry, acai), summer fruit (raspberry, apple, pear) and tropical (pineapple, lime, mint) flavours, the last of which is particularly refreshing when ice cold. The snazzily packaged drinks, made with proper pressed fruit juice, contain not just collagen (marine collagen, made from the scales of saltwater fish — don’t worry, no fishy taste lingers) but other nutrients: collagen-boosting vitamins C, E and multiple Bs, plus zinc.
