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.

IM SO FOCUSED I CAN FINISH THIS REVIEW!

It actually does help with clarity and focus and does not leave you with a sleepy after effect like other focus supplements.

No help

I never once felt like it helped or changed my focus. Either it’s a jar full of sugar pills or my brain is immune this product.

​​Thanks for leaving Alpha Brain a review! We're sorry to hear that it has not worked as you were expecting. 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. For some folks, it can take a couple weeks of consistent use to really start to feel the benefits. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team by emailing help@onnit.com for further assistance!

Nothing changed

Didn’t notice a difference at all. Took it for15 days straight (as directed). Never noticed a difference, so it didn’t make sense to but more.

Bad effects on me

It had the opposite effect on me. I was groggy and sleepy and couldn’t stay focused on what I needed to do.

Make sure you eat

It works well. I get very nauseous after taking 2. Maybe it will go away after taking it for awhile. I'm trying one a day to see if it gets better.
