Lactobacillus Acidophilus and Postmenopausal Osteoporosis Women

This study aims to evaluate the effect of Lactobacillus acidophilus supplementation on calcium status and bone densitometry in postmenopausal women in a randomized, double-blind placebo-controlled study.

This study has three steps; namely, 1st step is to prepare the diet supplementation of probiotics and placebo. 2nd step is to perform the randomized, double-blind placebo-controlled clinical trial. 3rd step is to analyze the effects of L. acidophilus UALa-01™ in postmenopausal women.
