Life Extension Essential Youth L-Ergothioneine, 5 mg, 30 Vegetarian Capsules

Life Extension's Essential Youth L-Ergothioneine is a longevity and healthy aging supplement designed to support cellular protection. It provides 5 mg of L-ergothioneine per capsule, an amino acid found in high concentrations in certain mushrooms, along with 5 mg of vitamin C from ascorbyl palmitate. The manufacturer notes that this dose is equivalent to the amount in 2 to 5 cups of white button mushrooms, offering a concentrated source for those not consuming mushrooms regularly.

This formula uses ErgoActive®, a registered trademark of Blue California, which is produced through a proprietary fermentation method to ensure consistent quality. The manufacturer references preclinical and clinical studies suggesting ergothioneine may help delay telomere shortening under oxidative stress and support cognitive, vision, and cardiovascular health, though these statements are not evaluated by the FDA. The product is gluten-free, non-GMO, and comes in vegetarian capsules, with a recommended daily intake of one capsule.
