We appreciate you taking the time to leave some feedback! Sorry to hear that Alpha Brain didn't benefit you. Every person reacts differently to supplementation, and it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take a few tries to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Unnoticeable effects

I feel no difference in my memory, mood, focus, etc., when I take alpha brain versus when I don’t.

Worthless.

Never felt or senses any sort of difference. Threw the second bottle away, waste of money.

No impact, not worth the money

Took it as directed, absolutely no impact to my memory, focus, or cognitive clarity.
