Summary

This study tested whether taking a probiotic called Lactobacillus acidophilus can help prevent bone loss and osteoporosis in women after menopause. 90 women aged 45-70 with a BMI between 27 and 35 took either the probiotic or a placebo. Researchers measured calcium levels and bone density to see if the supplement made a difference.
