Could a probiotic cocktail delay Parkinson's? new trial launches

NCT ID NCT07619560

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a daily supplement containing a specific probiotic, tryptophan, and branched-chain amino acids can slow the progression of early-stage Parkinson's disease. Researchers will recruit 120 participants and randomly assign them to receive either the supplement or a placebo for 12 weeks. The goal is to see if the cocktail improves motor, cognitive, and non-motor symptoms, and to build a model that predicts individual 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 Y7, tryptophan, and branched-chain amino acids (valine, leucine, isoleucine)

What this could lead to

If it works, this could point toward a simple dietary supplement that slows Parkinson's progression and improves motor and cognitive function.

What could go wrong

This is an early-stage trial with only 120 participants over 12 weeks. The supplement may show no benefit, and results may not apply to all Parkinson's patients.
