Longevity & AgingErgothioneine From Mushrooms May Shield the Brain Against Parkinson's Disease
Ergothioneine (ET), a thiol/thione compound found abundantly in mushrooms, is emerging as a potent neuroprotective nutraceutical against Parkinson's disease (PD). Unlike most antioxidants, ET boasts a ~1-month half-life in the human body, crosses the blood–brain barrier via a dedicated transporter (OCTN1), and accumulates preferentially in brain regions implicated in PD. Population studies show PD patients have 45% lower serum ET than healthy controls, and longitudinal data link low ET to accelerated cognitive decline. Pre-clinical models across C. elegans, Drosophila, rodents, and human neuronal cultures demonstrate ET reduces alpha-synuclein aggregation, restores mitochondrial function, lowers oxidative stress, and suppresses neuroinflammation. Early clinical trials confirm ET's safety and suggest potential efficacy, supporting further investigation as a disease-modifying strategy.
