This study evaluated the effects of vitamins C and E on bone turnover (total volume of bone that is both resorbed and formed over a certain period of time). Blood and bone density were analyzed in 533 women, of which 22 were current users of supplemental vitamin C or E. The results showed that vitamin supplements can suppress bone resorption, i.e. the transfer of calcium from the bones to the blood, a common cause of bone weakening. Further details can be found in the study.
