Summary

This study tests whether a dietary fiber supplement (soluble corn fiber) can help older men absorb more calcium and improve bone health. Thirty male veterans aged 60 and older will take the fiber supplement and then have their calcium absorption measured. The goal is to see if changing the gut bacteria with fiber can strengthen bones and reduce fracture risk.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: soluble corn fiber (a type of dietary fiber)
What this could lead to: If it works, this could point toward a simple dietary supplement to help prevent bone loss and fractures in older men.
What could go wrong: This is a small, early-phase study with only 30 participants, so results may not apply to everyone. The effect on actual fractures is not being measured directly.
