Can a daily probiotic capsule help older adults manage prediabetes?
NCT ID NCT07817290
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Researchers are testing whether a daily probiotic supplement can improve blood sugar, blood pressure, and body composition in people over 65 who have prediabetes or type 2 diabetes and known heart disease. Participants take one probiotic capsule each morning for 60 days, while a comparison group takes a placebo. The study measures blood sugar over time, blood pressure, weight, and other health markers before and after the supplement to see if the probiotic makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a probiotic dietary supplement
- What this could lead to
- If the probiotic helps, it could offer a low-cost, easy way for older adults with prediabetes to support their blood sugar and heart health.
- What could go wrong
- This is a very small, early study of 15 people, so any changes may be due to chance or not apply to others. Probiotics can cause mild stomach upset in some people.
