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!

I did not feel a thing.

I did not feel any difference. Probably does not hurt. But I do not think it works.

Alpha brain

Helps mental clarity and focus without side effects or crashing like caffeine or stimulants do.
