Meh

I'm a 47 year old male. After two weeks of taking a capsule every morning. I've been unable to notice any differences. I'll finish out the two bottles and then I won't purchase again. At this point I cannot recommend this product.

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 Service team for further assistance!

Didn't work for me

I didn't experience any benefit from taking Alpha Brain after taking the 15 day free trial. Glad I had the opportunity to try it out and not have to pay full price for it.

Cool stuff

This is one of the best nootropics I’ve taken and kicks in quickly. Make sure to take with a meal and take a two day break from taking it every week. I felt more stimulated and focused

Actually Works

Great for mental focus. Doesn’t give me gitters or any extra energy. If you want it for energy that won’t happen. But your thoughts will feel like they come out quicker, more fluid and more well thought out.

Too early to tell.

Maybe a 2nd bottle would be more efficient. I didn't notice a radical difference in clarity. Mornings have been fast pace, so I'd have to really focus on the next few takes.

Greetings! Thanks so much for giving Alpha Brain a shot. We all respond to supplements differently, not only in how they affect us but how quickly they affect us. We always recommend at least two weeks of consistent use to see if it's a good fit. Feel free to contact us directly at help@onnit.com if you need assistance with your order or have any questions!
