Effect of VSL#3 on Bone Mineral Density in Postmenopausal Women

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Menopausal Osteoporosis

In brief

Osteoporosis has a devastating impact on quality of life of postmenopausal women, and is a significant cause of disability and morbidity. Many drugs are approved for the prevention and treatment of osteoporosis, but are associated with high costs and side effects. Some data from animal studies suggests that supplementation with probiotics can safely treat and prevent osteoporosis. The probiotic VSL#3 is commercially available, is safe for human consumption, and has been widely used in human clinical trials, and has known health-promoting effects in both children and adults. The double-blind, randomized, placebo-controlled trial of VSL#3 will be conducted for 12 months in 40 postmenopausal women to determine if VSL#3 improves bone mineral density and related bone markers. Study visits will include all or some of the following procedures: a medical exam, urine collection, height and weight measurement, a blood draw to assess bone biomarkers, a DEXA (dual energy X-ray absorptiometry) scan to measure bone density, and health questionnaires. This is one of the first clinical trials proposed to investigate the effects of probiotics in bone in humans. If successful, this proposal will provide the first evidence that nutritional supplementation with the probiotic VSL#3 is a safe and effective strategy for preventing postmenopausal bone loss.
