Great product

Love this stuff. I'm a Computer Systems Engineering student at ASU, and after hearing about Alpha Brain on numerous accounts, I figured I'd give it a try. I do not regret that decision; Alpha Brain really does help you get your mind operating at better levels. I take it before writing a program or taking a test, or really anything else that requires intense focus. I experience clearer, smoother thought processes which accompany a comfortable energy surge. I wonder sometimes how much of it is psychosomatic, but it honestly doesn't matter because the results are now measurable, Alpha Brain works.

Okay

[This review was collected as part of a promotion.] Alpha BRAIN delivers mild to moderate cognitive benefits for many—especially in focus and mental clarity—but results vary, and it's not a guaranteed powerhouse. If you're comfortable with the price and potential subtle effects, it's worth a try. Just manage expectations—I’ve seen little benefit, and proprietary blends make it hard to assess true potency.

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!

So effective 😍

[This review was collected as part of a promotion.] I’m genuinely amazed by how effective this supplement is! I’ve only been taking it for a few days, but I noticed the benefits almost immediately. It completely eliminated the daily fatigue I typically experience, especially on certain demanding days. Now, I feel sharp, focused, and mentally clear—almost like something out of a sci-fi movie. I highly recommend it and will definitely keep repurchasing!

Totally recommended!!

[This review was collected as part of a promotion.] I tried Onnit Alpha BRAIN and was honestly impressed with how effective it was. I felt more focused and mentally clear within a few days, especially during work or tasks that needed concentration. The capsules are easy to swallow with no weird aftertaste, and I love that the ingredients are natural and caffeine-free, so there were no jitters or crashes. The packaging looks clean and professional, and the product feels high quality. While it’s a bit more expensive than some other options, I think the results and ingredient quality make it worth it.

No bad taste

[This review was collected as part of a promotion.] These pills have a neutral taste. I have been taking these daily with a meal as directed and I have not seen a big difference. Packaging is excellent. Most of the ingredients are good. They are a little overpriced for me.

Feels like a Caffeine/Pre workout kick.

Personally I am a big fan of many products on this website however this one just was not for me. To me it has the same feeling of like a Caffeine/Pre workout without the buzz. I could see how many people like it though as it definitely has you focused almost within 30 minutes of use.

Clear and focus !

[This review was collected as part of a promotion.] I’ve been taking this supplement for a few weeks now. I don’t have any negative side effects and actually feel I focus more on my task since I’ve started taking it. It’s easy to swallow and taste fine. No lingering after taste or smell. I am very pleased so far and look forward to continuing this Onnit Alpha Brain supplement indefinitely!!

Not too bad

[This review was collected as part of a promotion.] I was skeptical to try Alpha Brain daily cognitive support so I had my husband try it out with me. It helps with focus, memory and reaction time. We have taken this dietary supplement twice a day with our meals. My husband noticed more of a difference than I did after using the supplement for over a week. He also was lightheaded for first few days. Otherwise, he felt just fine and noticed a difference in his memory and being more focused at work.
