Ergothioneine for ALS
Also known as: ERGO, L-ergothioneine
ERGO's mitochondrial accumulation and metal chelation properties may protect motor neurons from oxidative damage.
Mechanism of Action
ERGO accumulates in motor neurons via OCTN1, providing mitochondrial antioxidant protection. It chelates copper (relevant to SOD1-ALS) and iron, reduces hydroxyl radical damage, and may support motor neuron viability under oxidative stress.
General mechanism: Unique thiol-histidine amino acid. OCTN1-transported, mitochondrial antioxidant, metal chelator, hydroxyl radical scavenger.
Current Evidence
No ALS-specific studies. OCTN1 transporter expression in motor neurons suggests relevance. Longevity data from epidemiological studies supportive.
Clinical Status: No ALS trials. Mechanistic rationale from OCTN1 biology.
Safety Profile
Extremely safe. Naturally present in diet (mushrooms). Dedicated OCTN1 transporter suggests biological importance. No side effects.
Key Research Questions
- Does ERGO protect motor neurons through OCTN1-mediated accumulation?
- Can ERGO chelation benefit SOD1-ALS copper dysregulation?
