Product Details
GeneIII® L-Ergothioneine + Milk Thistle combines two powerful antioxidant compounds designed to provide enhanced support for liver health and cellular resilience.
L-Ergothioneine is a unique amino acid-derived antioxidant because the human body has a dedicated transporter, OCTN1, specifically designed to absorb and retain it. Research suggests it accumulates in areas exposed to high oxidative stress, including the liver, brain, eyes, and mitochondria.
To further support the liver, we paired our ultra-pure L-Ergothioneine with concentrated Milk Thistle Extract, traditionally used to support healthy liver function and antioxidant defense.
Our L-Ergothioneine is produced through patented fermentation technology and refined to 99.99% purity for exceptional consistency and quality.
Key ingredients
30mg L-Ergthioneine and 80mg Milk Thistle Extract in every capsule.
How to use
Take 1-2 capsules daily with water, with or without a meal.
For best results, use daily for at least 6-8 weeks.
Whole-Body Wellness
Sleep Quality*
Quality sleep is when your body repairs and resets. By supporting cellular recovery and nervous system balance, ergothioneine helps your body recharge more effectively overnight, so you wake up feeling more rested and refreshed.
Natural, Steady Energy*
This isn’t a quick boost like caffeine or other stimulants. It’s sustained energy at the cellular level. Ergothioneine supports mitochondrial function - helping your body produce energy more efficiently, so you feel less fatigue and more consistent natural energy throughout the day.
Cognitive Health*
Ergothioneine is a unique antioxidant your body actively transports into the brain through a dedicated transporter (OCTN1). It helps protect brain cells from everyday oxidative stress-supporting clearer thinking, better focus, and long-term cognitive health.
Measurable Improvements Within 30 Days*
*Based on a 30-day clinical study using biomarker and self-reported outcome measures. Results may vary.
