Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. You've been contacted by customer support!

Okay

I felt a little sharper. Could’ve been placebo. I even doubled my dose and nothing was noticeable.

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!

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected while taking this product. We all respond to supplements differently, not only in how they effect us but how quickly they effect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you. After that time, if you’re still not feeling it, please feel free to reach out to us directly for further assistance.

Alpha BRAIN

Haven't notice much of an improvement to be honest, maybe expected too much.

May help some? Didn’t work for me.

Haven’t noticed much of a boost. May help a bit, but I’m not sold as the price.

I didn’t feel much different. I think you may have to take it longer to get the full affect.
