Product Overview
L-Ergothioneine (EGT) is a naturally occurring amino acid derivative produced by certain fungi and bacteria and concentrated in mushrooms. Uniquely, the human body actively transports EGT into cells through a dedicated transporter (OCTN1 / SLC22A4), where it accumulates in high-stress tissues such as skin, eyes, liver, and brain. This built-in delivery system makes EGT a genuinely cell-targeting antioxidant.
Key Features
- Cell-targeting antioxidant — transported into cells via the OCTN1 transporter
- Exceptionally stable thiol antioxidant that resists auto-oxidation
- Naturally mushroom-derived story with strong clean-label appeal
- Available in cosmetic grade and food/supplement grade
- Water-soluble white powder for serums, capsules, and powder blends
How It Works
- Cellular uptake: the OCTN1 transporter actively concentrates EGT inside cells — few dietary antioxidants have a comparable dedicated uptake system.
- Primary antioxidant action: EGT’s thione–thiol chemistry neutralises reactive oxygen species without becoming pro-oxidant itself.
- Mitochondrial & DNA protection: intracellular accumulation helps shield DNA, proteins, and lipids from oxidative damage.
- Metal chelation: binds free iron and copper ions, blocking the Fenton reactions that generate aggressive radicals.
Typical Applications
- Premium anti-aging serums and creams
- Eye-care and anti-pollution skincare
- Sun care and after-sun products
- Longevity, eye-health, and cognitive supplement formulas
- Mushroom-complex and immune-support blends
