Frequently Asked Questions
What is L-Ergothioneine?
L-Ergothioneine (L-EGT) is a rare amino acid and powerful antioxidant naturally found in mushrooms. Unlike most antioxidants, your body has a dedicated transporter called OCTN1 specifically designed to absorb and retain it in areas with high oxidative stress, including the brain, liver, eyes, and skin.
Research suggests L-Ergothioneine may play an important role in supporting cellular health, healthy aging, cognitive function, and resilience against everyday oxidative stress.
Can't I just get L-Ergothioneine from food?
You can, but typically only in very small amounts.
L-Ergothioneine is primarily found in certain mushrooms, though levels vary significantly depending on species, growing conditions, storage, and preparation. To reach the amount found in a single GeneIII capsule, you may need to consume several hundred grams of mushrooms daily.
GeneIII uses a patented fermentation-based process to produce highly pure L-Ergothioneine with consistent potency and quality in every capsule.
How do I take GeneIII L-EGT?
Take 1-2 capsules daily, with or without food.
L-Ergothioneine is designed to build up in the body over time through the OCTN1 transporter system. Consistency matters more than timing, so we recommend taking it daily as part of your long-term wellness routine.
Why should I take GeneIII L-EGT?
Modern life exposes our cells to constant oxidative stress from aging, poor sleep, environmental factors, and everyday metabolism.
L-Ergothioneine helps support the body’s natural defense systems at the cellular level. GeneIII L-EGT is designed to support healthy aging, cognitive health, energy production, sleep quality, and overall cellular resilience.
What makes GeneIII different is our commitment to purity, research, and quality. We produce our own L-Ergothioneine using patented biotechnology and achieve 99.99% purity, backed by rigorous testing and registered human clinical research.
When will I feel something?
Everyone’s experience is different. Some people report noticing improvements in areas like energy, sleep quality, or overall well-being within a few weeks of consistent use, while others may notice more gradual changes over time.
Because L-Ergothioneine works at the cellular level, it is best thought of as a long-term investment in healthy aging and resilience, rather than a quick stimulant or temporary boost.
