A BJJ tool.

It's a game changer in BJJ. You absorb the technique of the day better and your awareness and energy for the roll is consistent.

Not beneficial

[This review was collected as part of a promotion.] The Onnit Alpha BRAIN personally did not make a difference in my daily living. Despite taking it consistently, I found that there was no positive effect in my brain power. I would not recommend spending money on this product.

    Still on the fence

    Ive been taking it daily for the last few weeks and am not exactly experiencing the "actors" on commercials level of change in energy, focus, motivation, etc. I'll give it the rest of the 45 day supply before I decide to continue purchasing.

    Amazing product

    I didn’t think this would work for me. I saw the commercials and read the reviews but thought nah. Then I tried it and man this blew my mind. I felt more awake and sharp. Turned me into a believer.

    Domination cap

    There is no other way to say it. This stuff works and it is easily my most important supplement paired with a whole food diet and exercise it helps me dominate the day.

    Did not notice any difference

    I eat clean, exercise hard, follow a routine, and sleep well. Took these with my multi vitamin daily and felt absolutely 0 impact on memory or focus. Shocked at how much sponsors rave about it.

    Good Product but Just a Bit Overpriced

    Really enjoyed using this supplement. I definitely feel like this makes a difference when I take it with my memory and focus. Only negative I have is that I wish they were more affordable

    Gave me a headache

    I tried this because the site mentioned it was for women as well as men. I would have continued taking it but it gave me SUCH a SPLITTING headache each time.

    Does what it says

    I noticed an improvement in focus after the second day. I bought a second bottle and I'm still feeling the effects after a month. I still think is a little expensive for a two week supply, but the results are positive.

    Focused

    [This review was collected as part of a promotion.] I would use again, I felt like I noticed a difference a couple of days in. I felt like it helped me focus more. The capsule was on the larger side so that is the only negative.

    Better than anything I've ever tried

    I have tried multiple supplements to help focus, memory, sentence forming, cognitive thinking, etc. Alpha Brain is by far the best thing I have ever used.

    Great product

    I love alpha brain and I have used it for 5 months. The only reason it's getting 4 stars is due to the price, if each bottle was a full month supply then it would be amazing.

    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.

    Did not live up to the hype

    I have taken the product two times a day for a few weeks and have not noticed a difference in my health or brain function. I loved the idea of the Alpha Brain, however this is not a product I will purchase again especially with the high price.

    I was expecting more/better results.

    I would say “Alpha Brain” worked in the sense of “sharpness” and “quicker thinking”. I wouldn’t say it helped me focus or perform abnormally for myself. I would however try a second free trial see if it’s right for me

    I bought this 4 weeks ago and haven't noticed anything different. Maybe I was expecting too much but the reviews made it sound like they are the best thing since sunshine. They may be helping but I'm not sure. The reviews are Hiped up.

    Disappointed.

    I’ve been taking onnit for two weeks and haven’t seen any changes in my drive. Really disappointed because I was really hoping this would be effective.

    Alpha Brain early results

    I have not been taking this too long, but so far it feels like it’s helping me think better, and remember more. I may come back later with a five star upgrade.
