Didn't Work For Me

Unfortunately this product did not work for me. There were no noticeable effects. This was very disappointing.

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!

My Favorite Nootropic

Alpha Brains helps me with focus and memory. I feel improved recall and quicker 'on my feet' when presenting and during training sessions.

Helps keep my energy/focus up

I take one pill after lunch and it helps keep my energy up so that I am able to study after I get home from work.

It does not motivate me nor focus me

Took it and saw nor felt any difference in focus, energy, or any of the other adjectives the product promotors advertise.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

Meh

I took it religiously for 30 days. There was no significant difference to my daily life, memory, etc...

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. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Does actually improve focus

I like it. I definitely feel like it helps me feel more focused. I do however get headaches sometimes. Maybe I'm not drinking enough water though.
