Curious to see if the actual experience lives up to the formulation’s potential.

[This review was collected as part of a promotion.] Alpha BRAIN's mix of vitamins, amino acids, and herbal extracts looks promising for cognitive support. The blends aim to boost focus, memory, and brain function. The packaging is great! While the claims are intriguing, I’m curious to see if the actual experience lives up to the formulation’s potential.

Great idea

[This review was collected as part of a promotion.] These had little effect on me. They are bigger sized pills which I have no problem taking. However, I didn’t feel any different and sadly not more focused either. I have a high caffeine tolerance so I’m not sure if that is why.

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!

Good and Nice

[This review was collected as part of a promotion.] . This has mental clarity, promotes flow state and caffeine free and gluten free as well. It also has vitamin B6. I think this is easy to take I haven't felt the effects of these yet as it's been a few days but good for memory and focus This taste ok not bad aftertaste the packaging was nice and I recommend this

My memory and focus have noticeably improved

[This review was collected as part of a promotion.] has become a staple in my daily routine. Whether I’m studying or working on a new project, it helps me stay sharp and focused. I love that it’s caffeine-free, so I don’t have to worry about crashing later. With over 7.5 million bottles sold, there’s a reason this product is so popular

Subtle boost in focus and clarity

[This review was collected as part of a promotion.] I’ve tried Alpha Brain a few times because I was curious about nootropics and wanted help staying focused during long workdays. For me, it didn’t feel like a huge burst of energy like caffeine, but more like a gentle mental clarity. I did notice it helped me concentrate a bit better, especially when writing or working on tasks that usually distract me. One thing I like is that it doesn’t make me feel jittery or crash later. However, it’s kind of pricey for the results — I don’t think it’s life-changing, but it does give a slight edge in focus. Some days I didn’t feel much at all, so it’s hit or miss depending on my sleep and stress levels.

Gets the job done!

[This review was collected as part of a promotion.] As advertised, this helps you stay focus and provides constant energy stream without a rush thats followed by a crash. The ingredients are health conscious. Packaging is user friendly especially if you only got one hand to open the bottle for the capsule!

More harm than good

The first day I took 2 capsules with a light breakfast and within 3 hours had diarrhea and an upset stomach with a burning sensation which lasted through the night. Also, I found it difficult to sleep because of anxiety. It's the following day and my stomach is still upset. Onnit has some terrific supplements but for me, this isn't one of them.

Cognitive Support

[This review was collected as part of a promotion.] I started taking Onnit Alpha Brain daily supplements about a week ago. The idea of improving my memory and focus was beyond intriguing - and maybe too hopeful. It may just be me, but I didn't notice a dramatic difference. I received this product compliments of Influenster in exchange for my honest review. I will continue to take them until I finish the bottle. I want to be thorough in trying to support my memory and focus.

Didn’t feel any effect after two weeks of use

[This review was collected as part of a promotion.] I do like the product ingredients. I used Alpha Brain for two weeks and I’m not sure I felt any effects. A couple of instances I felt like my memory was slightly better but that could have just been a placebo effect. I was super excited to try this, but fairly disappointed by the results.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!
