Thanks for reaching out and leaving a review! Apologies that Alpha Brain did not work for you. Everyone 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 experience team for further assistance!

Don’t believe the hype!

For me it did nothing but give me headaches. Didn’t do what people say it does.

I’m not really sure about this one.

I can’t really tell any difference. I feel like it’s a placebo.
