Summary
Brief summary
Calcium supplementation has been shown to reduce the incidence of osteoporosis and related fractures. Currently Calsup (calcium carbonate) is marketed widely in Australia. This study is to compare the effects of Calsup with a newer calcium supplement, Citracal (Calcium citrate) on reducing serum markers of bone resorption. The hypothesis is that citracal may be equally effective in smaller doses and would have less side effects.
