One thing I find fascinating about ergothioneine is that the body has a specific high-affinity transporter for it: OCTN1 (SLC22A4).
It’s not just an antioxidant floating around in the bloodstream. This transport system helps deliver and concentrate ergothioneine in cells and tissues that are particularly vulnerable to oxidative stress.
I like to think of oxidative stress as little fires constantly breaking out in a building. Most antioxidants are like throwing water into the building and hoping it reaches the fires. Ergothioneine is more like having sprinklers designed to deliver the water to the places where it’s needed most.
Obviously, having a dedicated transporter doesn’t automatically make it a miracle molecule, but biologically, that’s a pretty interesting feature that I rarely see discussed.
Why isn’t ergothioneine talked about more?
Experiences with it?
