Plant-based probiotic/prebiotic to help keep bones strong with age

A randomized, double-blind, placebo-controlled, clinical trial of a probiotic/prebiotic supplement for the dietary management of age-related bone loss.

NIH-funded research Hebrew Rehabilitation Center for Aged · NIH-11311271

A plant-derived probiotic/prebiotic supplement is given to older women to see if it helps preserve or improve bone strength and bone density.

What this research studies

You would be randomly assigned to take either the synbiotic supplement (called SBD111) or a placebo for about 18 months without knowing which one you receive. The study focuses on women over 60 and includes bone density scans (DXA and quantitative CT), blood and stool tests for bone turnover and inflammation, and analysis of the gut microbiome. Staff will collect data at scheduled clinic visits to measure changes in bone strength, volumetric bone mineral density, and biochemical markers. The goal is to understand both whether the supplement helps bones and how it might work through the gut and inflammation pathways.

Who could benefit from this research

Good fit: Ideal candidates are women aged 60 or older with age-related bone loss or osteopenia who can attend clinic visits and agree to scans and blood/stool sample collection.

Not a fit: People under 60, men, or those with advanced osteoporosis already on prescription bone drugs may not be eligible or may not benefit from this supplement-focused approach.

Why it matters

Potential benefit: If successful, this could offer a safe, affordable dietary supplement option to slow age-related bone loss and lower fracture risk.

How similar studies have performed: Early animal studies and small human trials suggest probiotics and prebiotics can support bone health, but large, long placebo-controlled trials in older adults are still limited.
