Healthy aging support – An amino acid that supports healthy aging, ergothioneine is a powerful antioxidant that supports overall well-being—but levels decline as we age. This highly bioavailable supplement is a great choice for your healthy aging regimen.
Combat oxidative stress – As a stellar antioxidant, L-ergothioneine quenches free radicals that contribute to oxidative stress on our cells that happens over time. This oxidative stress is considered a key factor when it comes to aging.
Powerful dose – Life Extension was among the first to offer L-ergothioneine as a healthy aging supplement. Now, we’re proud to offer an even more powerful dose: 25 mg of ergothioneine in every capsule.
Ingredients matter – We use only the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
Live your healthiest life – We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
