Hard to know for sure
I like the concept of all the Qualia products, and have tried the Senolytic (2 months) the Night formula (1 month), and just a few days with the Mind (non-caffeine). I feel quite well, but I also felt pretty good before starting with these supplements -- so it's hard to say for sure. And some of the ingredients were already in my regular regimen. Of them all, I am most enthusiastic about the promises of the Senolytic supplementation.
