What is L-Ergothioneine?

L-Ergothioneine (EGT) is a unique, naturally occurring amino acid that functions as a powerful antioxidant, often referred to as the “longevity vitamin.” The human body cannot synthesize EGT, requiring dietary intake primarily from sources like mushrooms and beans.

A defining characteristic of EGT is its highly efficient cellular uptake. The body possesses a dedicated transporter (OCTN1) specifically designed to actively absorb and deliver EGT to areas most vulnerable to oxidative stress, including the skin, brain, and liver. Due to its targeted delivery, high bioavailability, and exceptional stability, EGT is a promising ingredient in anti-aging, neuroprotection, and advanced skincare formulations.
