Ergothioneine for Alzheimer's Disease
Also known as: ERGO, L-ergothioneine
Ergothioneine is transported into neurons by a dedicated transporter (OCTN1), suggesting an essential neuroprotective role.
Mechanism of Action
ERGO accumulates in mitochondria via OCTN1 transporter, providing persistent antioxidant protection against hydroxyl radicals and singlet oxygen. It chelates metal ions (Cu, Fe, Zn) involved in amyloid aggregation, inhibits Aβ-metal toxicity, and activates Nrf2.
General mechanism: Unique thiol-histidine amino acid. OCTN1-transported, mitochondrial antioxidant, metal chelator, hydroxyl radical scavenger.
Current Evidence
Blood ERGO levels are significantly reduced in MCI and AD patients. Higher mushroom consumption (ERGO source) associates with lower dementia risk. ERGO is being called the 'longevity vitamin'. Clinical trials planned.
Clinical Status: Biomarker correlation established. Classified as 'longevity vitamin'. Trials planned.
Safety Profile
Extremely safe. Naturally present in diet (mushrooms). Dedicated OCTN1 transporter suggests biological importance. No side effects.
Key Research Questions
- Is ERGO depletion a cause or consequence of AD?
- Can ERGO supplementation prevent cognitive decline?
