Sharper mornings, in their words.

"By week six I noticed I'd stopped re-reading paragraphs. I do the crossword in pen again — that's my little victory."

"I wanted something without caffeine because of my blood pressure. This is the first one that didn't make me feel wired — just clearer."

"Bought it for my dad, 78. Two months in, he's quicker on the phone — he tells me stories without losing the thread. Worth every penny."

"I'm a retired schoolteacher and I read every night. After about a month I stopped losing my place and re-starting chapters. That was the moment I knew."

"My wife noticed before I did — she said I'd stopped asking 'what did you just say?' at dinner. A small thing, but it means the world to us."

"I'd tried three other brain supplements and quit them all. This is the only one I reordered — no jitters, and my afternoons don't fall apart anymore."
