In two separate clinical trials involving a total of more than 2,000 women, strontium supplementation supported healthy vertebral integrity and composition. In a preliminary analysis of a three-year placebo-controlled, double-blind study of 5,091 postmenopausal women, strontium supplementation promoted healthy hip bones.
