The Science & Benefits of L-Ergothioneine (EGT)
L-Ergothioneine (EGT) is a rare antioxidant found in mushrooms and select foods. Clinical research shows it supports liver function, energy, brain health, and healthy aging — all while being safe and well-tolerated.

Liver Health — Clinically Backed Protection
EGT helps reduce oxidative stress in the liver.
Studies show significant improvements in liver enzyme levels (AST, ALT, GGT) within 30 days.
This means healthier detox, better metabolism, and long-term organ protection.

Energy & Physical Recovery
EGT supports mitochondria, your body’s natural energy factories.
Within weeks, participants reported up to a 40% improvement physical performance and reduced fatigue.
The result is natural, steady energy that lasts through your day.

Brain Health & Focus
EGT is one of the few antioxidants proven to cross the blood-brain barrier.
It protects neurons from oxidative stress, helping preserve memory and sharpen focus.
Supports long-term brain resilience against age-related cognitive decline.

Daytime Vitality & Sleep Quality
Clinical findings show a 51% improvement in daytime energy after 30 days of EGT use.
Unlike stimulants, EGT restores balance at the cellular level, helping you wake up refreshed and alert naturally.
