Why Should I Supplement With Essential Youth L-Ergothioneine?

In today's world, you don't have to be young to be youthful. With regular exercise and the proper nutrition you can fight against aging head on. And to help you on your quest, we created Essential Youth L-Ergothioneine. 

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.

So are you ready to fight back against aging? Defy your age with Essential Youth L-Ergothioneine from Life Extension.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.

My dog doesn't like it
Size: 5 in, Color: Orange
My dog wasn't a fan of this at all. He was curious about it, probably because he could smell it, but he wasn't sure about chewing it. It could be because his teeth squeak against it? Or maybe it has an odd texture? I don't know But this has sat in the toy bin untouched since the day we got it
