Brain boost

[This review was collected as part of a promotion.] I’ve been taking Alpha Brain for a bit now and honestly, I’m loving it. I feel way more focused and clear-headed, especially when I’ve got a lot on my plate. No weird side effects or jitters either—just smooth, steady mental energy. Definitely worth trying if you’re looking for a little brain boost

4/10

[This review was collected as part of a promotion.] I just have recently received this Onnit Alpha Supplement for brain support to help with memory lose. I’m not sure if it really works 100% due to different study. This supplement do come with some side effects like nausea and dizziness.

My Favorite Supplement

Induces a distinct focus and pleasant state of mind. My head feels clear, alert, and blissful when I supplement with it. I was able to breeze through reading a book for four hours straight, without having to take a break, while comprehending and obtaining the knowledge fully. Highly recommend if you desire to enhance your focus and memory.

ONE Bottle!

ONE bottle is all it took. I work as a parts sales rep for an agricultural equipment dealership. I was struggling at times to remember information that was crucial to my daily work. Found myself dazed and confused at times, especially during when I was overwhelmingly busy. I was spaced out, and foggy all to often. I've been at this job for 15 years, and just this year, all this was slowly happening! I'd been seeing ads for Alpha Brain on social media. Figured I try one bottle to see if it helped. After one week I could tell there was a difference. I could focus. I could remember specific things from previous YEARS. The brain buzz was gone! That ONE bottle was empty five days ago. The last couple of days have been a slow return back to the way things were before, and I hate it! My woman even noticed I was a little off this week. Thank You ONNIT for creating such an AWESOME product! I re-ordered AND subscribed this morning. I DO NOT want to be without ALPHA BRAIN!

Improved focus

[This review was collected as part of a promotion.] I have been taking the alpha Brain for 2 weeks now. I can tell a difference in how I stay more focused than before I started taking these. I take the recommended two capsules a day. If you have a hard time swallowing bigger pills this may be an issue, make sure you drink a lot of water to help with this.

Okay

[This review was collected as part of a promotion.] I have been using Alpha Brain for 1 month now and I have not really seen a huge Improvement in my memory. I really cannot say how effective this is, but I can talk about the capsules themselves. They are easy to swallow, do not have a bad taste and do not leave an aftertaste in my mouth.

Seems to help with focus

[This review was collected as part of a promotion.] These pills are really easy to take with no weird aftertaste. The first day I took them, I felt like I was able to focus a little more on what needed to be done. I wasn’t sure if this was a placebo effect or not, but after continued to use, I felt that my focus was better than normal. I don’t think there was any notable improvement in my memory. I do wonder if something like this should be cycled so as to not build up tolerance. I would also like to see the long term impact but short term I did notice some improvements cognitively so I feel confident in saying this does work to a degree.

May hit each person differently.

[This review was collected as part of a promotion.] The package was eye catching. They didn't have a taste. The ingredients were a natural source. For value, I can't agree or disagree. I didn't notice a difference in memory or focus, but reaction time was on point. I'd be willing to try again for a longer period of time to see if there's any changes .

Supplement

[This review was collected as part of a promotion.] I tried these for a better week or so before providing my review and I only noticed a slight difference when it came to focusing and memory. I recently started school again and thought this would be a good time to try these out
