It is advisable to attempt.

[This review was collected as part of a promotion.] The product's packaging is aesthetically pleasing, featuring a combination of black and gold accents and clear labeling. While dietary supplements can have varying degrees of effectiveness, I did not personally experience significant benefits from this particular product. I prefer supplements that are tasteless, and while the ingredients in this product are of good quality, the price point is somewhat high.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. 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 Service team, they'd be happy to help further!

Changed my life!

I have been dealing with brain fog for a couple of years. Every day was a struggle to focus at work. I had a hard time processing and retaining information. In the accounting world, that's just torture. Since taking Alpha Brain, my head feels clear. I have mental clarity and focus that I haven't had in a very long time. I can perform at a level that far exceeds what I was capable of before. Thank you ONNIT for giving me my life back!

Not a product I would try again

[This review was collected as part of a promotion.] I received this product from influencer and Alpha Brain in return for an honest review. I was excited at the claim that this product helps support Focus, Memory, and reaction time without the shakes that come with a caffeine load supplement. However I was disappointed when I felt no difference at all in any of those performance areas, instead it upset my stomach even when I ate before taking. I did give it a fair chance and took all 30 capsules hoping as the days progressed I would notice a better sense of well being.

Feeling the difference!

I had bought this initially due to curiosity and coming up to a huge period with exams and assignments piling up heavily I thought let give it a shot. This product is truly awesome, I could definitely feel that my focus is a lot sharper and found myself recalling words without using a thesaurus during assignments. The biggest thing for me however was how much it helped with my sleep quality. Having very rarely had any dreams (average once or so a month) to every single night dreaming and waking up feeling 10x better than usual, this product is has my huge stamp of approval. Highly recommended and already getting my friends onnit as well!

Feeling great with Alpha Brain!

[This review was collected as part of a promotion.] This stuff makes me feel great. I love taking it every morning. Easy to pop capsules leave no taste. A little bit pricey but this has some really good ingredients so it is well worth it! Bottle is easy to open too.

Potential is there

[This review was collected as part of a promotion.] It has potential, I was taking them, but I had some tests I needed to take and my doctor never heard of them, so he had me stop talking them a week prior to my test so I wouldn't interfere with my test results

Alpha Brain Daily Cognitive Support by Onnit

[This review was collected as part of a promotion.] I’ve been using Alpha Brain Daily Cognitive Support for a few weeks now, and I’m genuinely impressed with the results. As someone who often juggles a heavy workload and multitasking, I was looking for a non-caffeinated supplement to help boost focus, mental clarity, and memory without causing jitters—and Alpha Brain delivered. The biggest improvement I’ve noticed is in mental sharpness and word recall. Tasks that used to feel mentally exhausting—like writing, problem-solving, and staying organized—now feel more manageable and fluid. There’s a noticeable difference in my ability to stay focused for longer periods, especially during meetings or when working on detailed projects.

Give it a try

[This review was collected as part of a promotion.] I really love that this is caffeine free, as with any supplement you have to give it sometime, but I believe it is helping with focus without the rush or jittery feeling you get with a product containing caffeine.

Memory and focus

[This review was collected as part of a promotion.] This onnit alpha brain memory and focus supplement was horrible for me. After the first use, i got a very bad headache and nausea. I didn't put it to using these right away and continued taking them for a couple more days, and it happened after each use. I discontinued using these and threw them away. For me, I would never try again, but the results may be different for you.
