A controlled trial of the effect of milk basic protein (MBP) supplementation on bone metabolism in healthy menopausal women. 

In a study of healthy menopausal women, the effect of MBP on bone metabolism was evaluated. The results show a significant mean rate gain of lumbar BMD in the MBP group, compared to the placebo group.  The authors conclude that MBP supplementation effectively prevented bone loss in menopausal women, inhibited bone resorption, while maintaining the balance of bone remodeling.
