Strontium is a naturally occurring element in the bones of all people. Strontium ranelate, a particular form of strontium, is a medication prescribed across Europe and Australia that has been proven to treat and prevent osteoporosis and related fractures. Strontium citrate is yet another form of strontium and is a widely available over-the-counter nutritional supplement promoted to “improve bone health.”
Unlike strontium ranelate, strontium citrate is not a prescribed medication and is inexpensive.
Researchers in the UC Davis Division of Endocrinology, Clinical Nutrition and Vascular Medicine are trying to find out whether strontium citrate, which women can buy without seeing a doctor or paying a drug company, can be used to improve bone health. The researchers are looking for post-menopausal women at least one year but no more than eight years past their last menstrual period to help find an over-the-counter and inexpensive way to prevent osteoporosis and fractures.
Participation includes a half-hour screening visit with a blood draw at UC Davis Medical Center, and a blood draw and free DEXA scan at the VA Northern California Health Care Center. Participants will be randomly assigned to one of two groups:
- Group 1 takes strontium citrate plus calcium and vitamin D for three months.
- Group 2 takes a placebo plus calcium and vitamin D for three months.
During the three months, participants will make two half-hour visits to UC Davis Medical Center for short questionnaires and blood draws. DEXA scans and test results will be provided to participants at the end of the study.
