I take Cod Liver Oil and Glucosomine but now the BBC recomend it I might be wasting my money.No seriously the multivitamin thing I believe is a waste of time if you have a reasonably balanced diet.Each of us is slightly different(Yes you are unique),excess vitamens are discarded by the body as waste(not sure whether tapeworms like them) but vitamins taken to great excess are dangerous. Don't panic. Just like salt,water,carbohydrates,proteins etc. we need this stuff to have a healthy life, but in moderation.
