Gut health boost: could probiotics help diabetic kidneys?
NCT ID NCT05674981
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a probiotic supplement containing two live bacteria strains could help people with diabetic kidney disease. Fifty adults with type 2 diabetes and early-stage kidney problems took either the probiotic or a placebo daily for 6 months. Researchers measured changes in kidney function and blood sugar levels to see if the probiotics could slow disease progression.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Probiotic supplement containing Lactobacillus reuteri ADR-1 and Lactobacillus rhamnosus GM-020
- What this could lead to
- If it works, this could point toward a simple, safe way to help manage diabetic kidney disease by improving gut health.
- What could go wrong
- This is a small, early-stage trial with only 50 participants. The results may not apply to everyone, and the benefit might be small or not clinically meaningful.
