First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking a daily probiotic drink called Goodbelly for 6 weeks could improve blood vessel function and reduce inflammation in 215 adults with heart disease or type 2 diabetes. Researchers measured blood markers and gut bacteria to see if the probiotic made a difference. The goal was to find a simple way to lower heart attack risk by changing the bacteria in the gut.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Goodbelly probiotic (dietary supplement)
What this could lead to
If it works, this could point toward a simple probiotic supplement to help manage heart disease risk by improving blood vessel function and reducing inflammation.
What could go wrong
This is a small, completed trial with no phase designation, so results may not be conclusive. The probiotic is a dietary supplement, not a drug, so any benefits are likely modest and not a replacement for standard treatments.
