Why we built Mainstay

Somewhere along the way, the world started telling women in their seventies and eighties to make peace with what the years took. We built Mainstay because we do not believe that.

The energy, the sharpness, the say over your own day — those did not leave because of who you are. They ran low because your repair genes ran short of the fuel they need. That is the thief. Not you, and not your family.

Mainstay Vivacelle is built around that fuel — NAD+ — with two plant helpers for the repair genes: quercetin and Japanese knotweed extract standardized to resveratrol. Two capsules a day, made to put the fuel back.

The prize is not a smaller life carefully kept. It is what the years took. Take it back.
