Alpha Brain!

This stuff is amazing! When I have big projects coming up, I know I need to be consistent with Alpha Brain and exercise. This makes me the best version of myself with clear thoughts and ready for action!

Onnit is the BEST!

Best nootropic out there unless you start making your own, which is way to much work and research for me.. and I have tried. These guys make it easy and I know you can trust Onnit and their owners.

Must have!

Mental sharpness and clarity can be a struggle for anyone these days, using this product has helped me keep my edge at work and at home. Keeping up with all the constantly moving parts in life can be a struggle but this product simply increases your ability to concisely work through your day no matter how busy.

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.

Not 100 percent sold on it

Thought I was noticing a difference, but feel i am not. Might try the black label next and give that a try before giving up on it.

reply from Onnit Customer Service

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation 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 time 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! -- Kristen ONNIT Customer Service Associate #getonnit

Nope

Made me sick each time I tried it. I got extremely nauseated and threw up many times which included bouts of shakyness.
