Gut Microbes Point to Simple B Vitamin Therapy for Parkinson's

A study links gut microbiome changes in Parkinson's disease to lower levels of riboflavin (B2) and biotin (B7), reduced short-chain fatty acids, and thinning of the intestinal mucus, suggesting that oral riboflavin and biotin supplementation could be a simple therapeutic approach; findings come from analyses of patients and controls across several countries, indicating a gut–brain pathway but the treatment would likely require personalized assessment.
