Fight back against premature aging with Essential Youth L-Ergothioneine. Our novel longevity formula delivers 5 mg of ergothioneine. This amino acid, found in high concentrations in certain mushrooms, has piqued the scientific community’s interest due to its cell-protective properties and its great promise in supporting healthy aging.

Support longevity at the cellular level—for an essentially youthful you.

Essential Youth L-Ergothioneine

  • L-ergothioneine offers powerful cellular protection against oxidative stress
  • May support healthy cellular aging by delaying telomere shortening
  • May support cognitive, vision and heart health

Why ergothioneine?

Ergothioneine is found in different food sources and in high concentrations in certain mushrooms (your body can’t make it). A new proprietary fermentation method has made it possible to provide supplementation of this nutrient. Studies have shown this amino acid has a highly specific mechanism to transport ergothioneine into cells and it is thought to play a crucial role in supporting long-term health. Our innovative formula helps maintain healthy ergothioneine levels to help ensure your body gets enough of this cell-protecting amino acid.

Our innovative formula helps maintain healthy ergothioneine levels to help ensure your body gets enough of this cell-protecting amino acid.

Ergothioneine is an amino acid that’s widely distributed throughout your body, but levels have been shown to decline as we age. Your body can’t produce it, so you must get it through your diet—it’s found in a variety of food sources, but with the highest concentrations in certain types of mushrooms.

This food-derived amino acid is thought to support long-term health through its free radical quenching and cell-protective properties. What’s more, the body has a highly specific mechanism to transport ergothioneine into your cells, suggesting it’s crucial for overall health.

But if mushrooms aren’t your thing, you can still get the longevity-promoting benefits of ergothioneine with our innovative Essential Youth L-Ergothioneine formula. One daily capsule provides as much L-ergothioneine as 2 to 5 cups of white button mushrooms.

Longevity and telomere support

Ergothioneine has been shown to delay telomere shortening due to oxidative stress. Why would you want to delay telomeres from shortening? Your telomeres are like protective caps at the end of your chromosomes. As time goes by, these telomeres shorten naturally, in step with your aging process. In a preclinical study, L-ergothioneine had a protective effect on telomere length and slowed the rate of telomere shortening under oxidative stress conditions.

Brain and vision health

Low levels of ergothioneine in older adults have been linked with cognitive decline. In preclinical studies, ergothioneine showed beneficial neuroprotective properties from oxidative stress, supporting overall cognitive health.

The cell-protecting properties of ergothioneine have also been linked to vision health.

Cardiovascular health

A 2020 clinical study found that higher ergothioneine levels were associated with healthier diets and with heart health.

Add Essential Youth L-Ergothioneine to your wellness routine—fight oxidative stress and support a youthful you at the cellular level!
