Could a daily probiotic pill keep your heart in rhythm?
NCT ID NCT07568964
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking a daily probiotic capsule for 12 weeks can reduce the chance of atrial fibrillation (AF) returning in people who have just had a cardioversion (a procedure to restore normal heart rhythm). Fifty-six adults aged 40 and older with persistent AF will be enrolled. All participants will receive standard blood-thinning and heart-rhythm medications, and half will also get the probiotic. The main goal is to see if probiotics lower AF recurrence.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Probiotics (25 billion CFU per capsule daily for 12 weeks)
What this could lead to
If it works, this could point toward a simple, low-cost way to help prevent atrial fibrillation from coming back after cardioversion.
What could go wrong
This is a small, early-stage trial with only 56 participants, so results may not apply to everyone. The effect of probiotics on heart rhythm is still uncertain.
