Probiotic trial found no clear bone-health advantage after menopause
In postmenopausal women, a probiotic supplement did not clearly improve hip-area bone density or estimated fracture risk compared with placebo over 48 weeks. This does not establish equivalence.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The tested probiotic did not show a statistically clear advantage over placebo for bone density near the hip or estimated fracture risk. Blood markers of bone activity also showed no mean difference between groups from the start to the end of the study. These results concern this supplement and population; they do not establish that every probiotic has the same effects.
The abstract reports significance tests but not the size or uncertainty range of treatment differences. Fracture risk was estimated with a prediction tool, rather than established through a reported comparison of actual fractures.
What researchers found
Bone mineral density at the femoral neck, near the hip
Probiotic versus placebo over 48 weeks; the test comparing changes over time was not statistically significant (p > 0.05).
What was measured
Researchers measured bone density at the femoral neck, near the hip, and calculated fracture risk using the FRAX assessment tool. They also measured blood markers of bone-cell activity at several points during the study.
Change over time differed from treatment benefit
Across treatment assignments, bone density declined and estimated fracture risks increased over time. Those overall changes do not show that the probiotic caused them; the comparison of changes between probiotic and placebo did not find a clear difference.
