Taking Alpha Brain makes me feel clearer in my thoughts, and more mentally energized. When I don't take it in the morning by the afternoon I feel more mental fatigue.

I didn't notice any difference after a month of consistent usage. I took as recommended which meant each bottle lasted 15 days. For the expense it just isn't worth it for me.

Didn't feel much unless I had alpha brain with a cup of coffee. Coffee, or AB alone wasn't doing much for me but together, I experienced a bit more energy and better focus.

My husband and I have been taking Alpha BRAIN for a month now. We are both very happy and ordering more. You don't feel jittery or anything like that. We both feel like our concentration has been improving and the midday slump too!!

I have been trying out Alpha Brain for around 3 months now and I have to say if there is one product made to help you regain your concentration and stay mentally sharp then it has to be Onnit's Alpha Brain. Thanks for such a good product.

You can literally tell a difference, i didnt think it was working at first, but I ran out and now being off it for a couple days I feel like I can’t think straight. Haha Definitely helps when you have a thousand things going on at once.

I'm always skeptical of these products but i am pleasantly surprised. The biggest thing I've noticed is how quickly I can recall things when asked questions

Alpha Brain keeps you sharp and on task while you really need to concentrate. It is subtle in its effect and last for a few hours, but mild enough that you barely notice it leave your system. An excellent way to 'Get Stuff Done'!

Made me very nauseous and I got violently sick without not much cognitive benefit, unfortunately. Think I am past the refund period from my purchase, but doesn’t seem to work well for me personally.

I was very skeptical at first and thought it was yet another make belief pill. But i was shocked to actually start to see a difference. Definitely worth a shot for anyone
