Ahh maybe

To be 100 percent honest I don’t know if this stuff works. The first few days I was excited about taking it but after about the 3rd day that kinda wore off. I do not notice any difference now.

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!

Free trial!!!

Appreciated the trial. I did not notice a difference while taking it but I feel that doesn’t mean others won’t. I’d say you should try it and see if it works for you.

Onnit Alpha Brain

This stuff is awesome! One of the best brain formulas I have ever tried. We are featuring it on an endcap in June and I can't wait to get the other kinds of Alpha Brain and try them. Truly an amazing formula. It kicks in right away, too.

Amazing!

This pill helps with my day-to-day work week. I like to take 1 pill early in the morning and the 2nd in the afternoon. It helps so much with my focus during conference calls as well as with the projects I manage. Definitely recommend!

Nice little Boost!

[This review was collected as part of a promotion.] This product seems to help with my focus as advertised. Im enjoying the little extra boost to help get me through my day. I take them once a day in the morning

Not what I expected

I felt nothing no improvement at all not even after the 2nd and 3rd day :( I was really disappointed. So I will stick to quantamind. I’m really glad I didn’t purchase the black label alpha brain.

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 affect us but how quickly they affect 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.

Memory and focus

Stuff works really well, makes my mind feel clear and focused. I fast throughout the day and find that taking 1 in the morning and 1 mid day works best and doesn’t overload me.

Good Product!

[This review was collected as part of a promotion.] The Alpha Brain supplement is good. It helps you to focus more. It also helps with your memory. The taste is not bad. I haven’t had any side effects.
