Parkinson’s disease reportedly linked to fewer gut bacterial genes for making vitamins B2 and B7

SmartScience, citing a study in npj Parkinson’s Disease, says researchers found a significant reduction in gut bacterial genes responsible for making riboflavin (B2) and biotin (B7) in Parkinson’s patients. The account describes a possible mechanism in which vitamin shortages thin the gut’s protective mucus layer, allowing toxins into the bloodstream and triggering neuroinflammation. It suggests supplementation could alleviate symptoms for a subset of patients, while noting that further clinical trials are needed to confirm dosage and efficacy.
