not worth the price

I bought Alpha brain after hearing about it from the Joe Rogan podcast and at first I noticed a better muscle connection will weightlifting and other training however it was just a placebo effect after I stopped taking it for a little bit to see if there was any difference I did not notice anything different with my mental focus or boosted memory and that even without it the muscle connection was still there. I really wanted to like this product but after trying it just is not worth it

More energy

[This review was collected as part of a promotion.] I've taken alpha brain for a couple weeks now. Honestly don't really feel much different. I do seem to have more energy throughout the day and maybe that is a direct effect. It does not have the normal vitamin type aftertaste like some do when you take them.

did work

[This review was collected as part of a promotion.] Alpha BRAIN helps me focus without the crash or jitters. I feel more clear-headed and less distracted, especially when working or studying. It’s caffeine-free, which I love. A bit pricey, but it works.

Great product

[This review was collected as part of a promotion.] These supplements have been a game changer for me while studying and working because it has made it easier for me to focus. I tend to struggle focusing but after taking these supplements I don’t have that issue. Also I love how easy they are to take does not leave weird after taste.

Improved clarity and focus

[This review was collected as part of a promotion.] After taking this for a while I’ve started noticing improvement in mental clarity and focus. I appreciate that the combination of ingredients is designed to promote a balanced approach to brain health, offering cognitive support and stress relief. I didn’t notice any aftertaste and the packaging is simple to get opened and the benefits definitely make this a great value for your money.

Great concept and clean ingredients, but unfortuna

[This review was collected as part of a promotion.] I was genuinely excited to try Alpha BRAIN from Onnit after seeing so many people describe it as a game changer for focus, memory, and mental clarity. That’s exactly what I’ve been trying to improve in my own daily performance. The packaging is clean and professional, and the ingredients seemed promising — especially because they’re natural and well-known in the cognitive space. The capsules have no strong taste, which I appreciated. I followed the recommended dose and later tried taking two capsules, hoping for a clearer effect. Unfortunately, I didn’t experience the benefits others mentioned. Instead, I felt overstimulated and more reactive, which led me to stop using it. Effectiveness for me was limited, but I understand supplements affect everyone differently. I think it could be a good option for some people, and if it works, the value makes sense. I might give it another try under different conditions, and I’m thankful for the opportunity to test it.

Works great

[This review was collected as part of a promotion.] The effectiveness of these two capsules shocked me! I work in education, and always have a million things going on or coming at me, not to mention the curve balls life has thrown lately! I’ve been able to focus, not forgetting important tasks and get done all the things needed! I’m already looking into where I can purchase these to continue in my regimen! No matter the cost!

Made me feel unwell

[This review was collected as part of a promotion.] At first, I didn’t notice a difference after taking this product. But about 3 hours later I began feeling dizzy and foggy. I went on to read other reviews with this same feeling. I guess my body didn’t like this supplement, so be cautious when trying.

Good

[This review was collected as part of a promotion.] After a few days of use I’ve noticed a bit of a difference while at work. I’m able to concentrate better. Please follow directions and take with a bit of food. No unpleasant after taste. And no jittery feeling that some competitive products have.

Unsure

[This review was collected as part of a promotion.] I’m honestly not sure how I feel about these. It is an awesome idea but I’m not sure how much of a difference I actually felt after taking one. I cannot tell if it was placebo effect or not. Had no taste. Easy to open the bottle. Definitely on the expensive side.
