Summary

This pilot study tests whether taking a synbiotic supplement (a mix of probiotics and prebiotics) for 10 weeks can lower TMAO levels and improve other heart health markers in 80 adults who recently had a heart attack. The goal is to see if changing gut bacteria can help prevent future heart problems. This is an early-stage study to gather data for larger trials.

What this could mean

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

Active substance: synbiotic supplement (probiotics and prebiotics)
What this could lead to: If it works, this could point toward a simple, low-cost way to improve heart health after a heart attack by targeting gut bacteria.
What could go wrong: This is a very early pilot study with only 80 people. It may not show a clear benefit, and results may not apply to everyone.
