So far so good.

So far I like it. I feel like I need to try it a little longer. Seems like the effect was cumulative. I'll probably buy one more bottle and see if it continues. It is a little pricey though.

I do not recommend

I took the product around 9:30 a.m. with breakfast. By noon, I was very sick to my stomach and was in bed for the rest of the afternoon. I plan to try to get a refund.

Sharp?!

Well what can I say? I'm intrigued..have only had one bottle but have felt a little more alert and definitely more pro active, will keep going with it and write another review another bottle down line, worth trying!

Disappointing

I did not feel any change in cognitive performance. I bought the product because of Joe Rogan taking it. I wish I could have seen better results. Thanks, Onnit :(

Hey there! Sorry to hear if you didn't experience the results you expected with Alpha Brain! If you just took the product a couple times and noticed some difference, it may be beneficial to try for at least a solid two weeks before you decide whether or not it's working! For some people, they can tell a change after the first dose, but many others needs a little bit more time to see a difference! :)

Alpha brain? Nope

I’ve been taking this for 3 weeks now and all I can say is meh. Had one day where it actually felt a difference but outside of that nothing. It’s way to expensive. Save your money.

Alpha Brain

Great stuff. helps my energy levels. I will take these after lunch instead of a energy drink. Gives me that final push for the end of the day. What you read is what you get Memory and Focus.

I was a skeptic

I go into everything skeptical, but hopeful. After about 4 days I noticed my memory recall was incredible. I was also having an easier time talking with people. I’ll definitely be buying more.

You need to try it.

[This review was collected as part of a promotion.] This supplement is very good for the brain, it helps me to stay focus and also helps with my memory. This is very useful and highly recommended!….

Does Not Work

Took it everyday for about 2 weeks. Not once did it enhance or change my way of thinking. Not once did it motivate or gave me energy to get anything done.

Give it a try

I really like this. At first I wasn't sure, but once it built up in my system I could tell a difference. Now I take it along with my vitamins as a part of my daily routine.
