Summary

This study tests a new functional drink made with chicory inulin, B-vitamins, and vitamin D to see if it can improve constipation and overall well-being in people with Parkinson's disease. About 56 participants will drink either the active supplement or a placebo twice daily for 12 weeks. Researchers will measure changes in diet, gut health, Parkinson's symptoms, and quality of life.

What this could mean

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

Active substance: A functional drink containing chicory inulin, folic acid, vitamin B12, vitamin B6, riboflavin, and vitamin D
What this could lead to: If it works, this could provide a simple dietary supplement to help manage constipation and improve nutrition and quality of life for people with Parkinson's.
What could go wrong: This is a small, early feasibility study with only 56 participants, so results may not apply widely. The drink may not significantly improve symptoms or could cause digestive discomfort.
