Onnit / Alpha Brain Review

Not much mental boosting or change in my day to day. Would hesitate to purchase again.

reply from Customer Experience

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 be dumb

I notice immediately when I run out. I have to keep this in my system, otherwise I feel dumber.
