Okay

[This review was collected as part of a promotion.] I recently tried ONNIT Alpha Brain, and I have to say, I'm impressed! This dietary supplement is designed to support memory and focus, and I definitely noticed a difference during my daily tasks. The capsules are easy to swallow, and I appreciated that they contain natural ingredients. After taking Alpha Brain for a few weeks, I felt more alert and able to concentrate for longer periods. It seemed to help with my clarity of thought, especially when I was working on complex projects. I also liked that it didn't give me the jittery feeling that some energy supplements do. Overall, I would recommend ONNIT Alpha Brain to anyone looking to enhance their cognitive function in a natural way!

Waiting for results

[This review was collected as part of a promotion.] I haven’t really seen any changes yet, so this is why I reviewed this way. I do like that you get a lot in the bottle, and that it’s made with trustworthy ingredients! I just didn’t see a change for myself. I am continuing with them to see if anything happens. I do think the packaging is nice, and the taste is not bad

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Caffeine free supplements that work!

[This review was collected as part of a promotion.] Onnit’s Alpha Brain supplements are great for improved focus and mental clarity, memory recollection, while also being caffeine free. I do recommend testing out a smaller dosage first as there are some side effects (I experienced a bit of nausea). Also, make sure you are not taking this on an empty stomach!

Clearer thinking

I've used Alpha Brain off and on over the past year. Typically only when I know I've got a data heavy work day, important meeting/presentation, or playing a sport requiring quick decision making (Hockey). I really like how this supplement helps me think more clearly and seems to help clear some of the cobwebs. Highly recommend Alpha Brain to anyone looking to make connecting the next thought or increasing focus easier.

No improvement

[This review was collected as part of a promotion.] I didn’t find this product improved much of anything after 30 days of taking it. It claims to promote mental clarity and help with focus and reaction time and I didn’t experience any of that. It doesn’t taste like anything which is good, but I definitely would not have purchased this product.

Easy to swallow and digest, promising results

[This review was collected as part of a promotion.] I have used the Onnit Alpha Brain for one week and I can already feel a difference in my focus and clarity. The Aloha Brain vitamins are easy to swallow and aren’t harsh on my stomach. I will continue to use them and hopefully continue to see progress.

Had some great focus days!

[This review was collected as part of a promotion.] I have really enjoyed trying my Alpha BRAIN supplements. The capsules are easy to swallow and they don’t upset my stomach at all. While it could be a coincidence, I’ve definitely noticed some very focused and productive days since I started taking them. I believe it would take consistent use over 4–6 weeks to really gauge any long-term improvements in brain or memory function, but so far, the experience has been a positive one. All in all, I think Alpha BRAIN is worth trying if you’re looking for a potential boost in focus and mental clarity.
