Improved focus

[This review was collected as part of a promotion.] I have been trying the Alpha Brain suppleme ts for a little over a week now. I do feel more focused with better energy. The ingredients are high quality, and there is very little taste. I will definitely continue using this product and update again further down the road.

Okay

[This review was collected as part of a promotion.] I’m not a big fan of large pills but these were easy to take. Packaging was not hard to open. There was no bad taste. As for its effectiveness I didn’t notice much focus going on. I was hoping it would help me zero in on some tasks but I didn’t notice a difference. I might work for others as it does have great reviews.

Love

[This review was collected as part of a promotion.] Onnit Alpha Brain is a great supplement for boosting focus and mental clarity. I noticed improved concentration and memory recall within just a few days of use, especially during busy workdays or creative tasks. It’s caffeine-free, so there’s no jittery feeling—just clean, sustained mental energy. Highly recommend for anyone looking to enhance their cognitive performance naturally!

For other people

[This review was collected as part of a promotion.] My friend and I took this around 9 am she had a sandwich and I had a few bites to eat, and she felt nauseous by 12 and I started feeling it around 1:30. This would work better for other people. We had to leave work and go home early.

Doesn't do anything.

Another supplement scam. I study languages all day, and it didn't make a difference. I made sure to test myself with flashcards to have some qualitative measurement, but I performed as I usually did. I felt slightly less agitated throughout the days I was taking it, but that's not worth the price.

reply from Customer Experience

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. Being that we're all unique individuals, it's expected that we have a range of responses, since supplementation is not one size fits all. With Alpha Brain working to help memory, focus, and processing speed - sometimes it can take a few tries to notice these effects.  Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our customer experience team, they'd be happy to help further!

Alpha brain

[This review was collected as part of a promotion.] These alpha brain from onnit are a great way to support some high functioning skills that we need on an everyday basis. These alpha brain supplements support focus , reaction time and memory. These pills have provided such a unique way of supplementing these daily tasks and they work great.

Meh save your money

[This review was collected as part of a promotion.] Grateful to have received this product to sample, however; I wouldn’t say I noticed much of a difference. Experienced minor but uncomfortable side effects (headache, nausea) and an unnoticeable difference after weeks of use.

Overwhelmed and feeling lost

Have you ever had so much to do that you don’t know where to start so you don’t start on anything and by not starting on anything, it just adds to your stress?! That’s me to a T. I’ve ordered so many supplements that never worked. When I came across this, I did not have high expectations. I bought the lowest supplant package because I was not expecting this to work and figured I’d be returning it so why would I purchase more than 1 month supply. Let me tell you… This product has far exceeded my expectations. I get so much done during the day and it sometimes even hard to turn it off at night because I’m so motivated to get stuff done. I haven’t had the energy to clean my bathroom for an embarrassing amount of time. I took this supplement and got down with a tooth brush and some comet and it’s the cleanest it’s probably ever been. I have been working on my website for 3 months and have done more work in the last 2 weeks than ever before. I no longer have to think about what has to be done and dwell on it. I know what has to be done and I do it. No more overwhelming feeling of a lost that keeps on growing. I recommend this to anyone who feels lost and doesn’t know where to start.
