Brief Summary

Prebiotics have been linked to increased calcium absorption in animal and human studies (particularly in adolescents and in premenopausal women). Similarly, probiotics have been found to benefit calcium homeostasis in pregnant women, and to promote bio-mineralization in animal models. The effect of symbiotic on calcium absorption has been tested in rats, but not in human studies. The primary objective of this study is to investigate the effect of daily consumption of a functional symbiotic yogurt containing inulin and Lactobacillus rhamnosus compared to a control yogurt, on calcium absorption in young adult women. A secondary objective is to relate changes in calcium absorption following yogurt consumption, with calcium metabolism, vitamin D status, bone mass, calcium intake and overall composition of habitual diet.
