What is L-Ergothioneine?
C9H15N3O2S
MW: 229.3 g/mol
CAS: 497-30-3
Unique Sulfur-Based Amino Acid
A naturally occurring histidine-betaine with a unique thiol group providing extraordinary antioxidant capacity. First discovered in 1909, EGT has been called the "longevity vitamin" by leading researchers.
Targeted Cellular Uptake
Unlike other antioxidants, EGT is actively transported into cells via the OCTN1 transporter. It concentrates in mitochondria and tissues exposed to oxidative stress.
💡 Clinical Significance
EGT levels decline with age and are depleted by UV exposure, pollution, and oxidative stress—making supplementation crucial for maintaining cellular health and skin vitality.
Powerful Benefits for Cosmetics
Superior Antioxidant
Significantly more powerful than traditional antioxidants like vitamin C and E. Neutralizes multiple reactive oxygen species.
Anti-Aging Properties
Supports skin health and activates longevity pathways. Protects mitochondrial function and cellular energy.
UV & Blue Light Protection
Shields against photoaging, environmental damage, and digital screen exposure. Prevents oxidative stress from light.
Cellular Protection
Unique transporter-mediated uptake ensures EGT reaches where it's needed most—inside cells and mitochondria.
Stable Formulations
Compatible with various cosmetic bases—aqueous and anhydrous. Excellent stability profile for product development.
Proven Efficacy
Backed by extensive scientific research, clinical studies, and protected by multiple Mironova patents.
