Fifty-one peri- and early postmenopausal women aged 45–60 years were randomly assigned into one of three treatment groups for 6 months: control, low BC (392 mg/day) and high BC (784 mg/day); and 40 women completed the trial.

Six-month changes (%) in peripheral IL-1β (<em>P</em>=.056) and RANKL (<em>P</em>=.052) for the high BC group were marginally significantly lower than the control group. Six-month changes in whole-body BMD were inversely correlated with changes in RANKL (<em>P</em><.01).
