It is not for kids

[This review was collected as part of a promotion.] In this thoughtfully designed package from Onnit, I received Alpha BRAIN®—a supplement created to support daily cognitive performance. The box arrived well-organized and eye-catching, featuring a motivational message that read, “Your day is about to get a lot more focused.” Inside, nestled carefully in tissue paper, was a sleek bottle of Alpha BRAIN®. This caffeine-free blend is formulated to help improve memory, focus, and cognitive processing speed. According to the packaging, Alpha BRAIN® delivers key nutrients that help build an optimal environment for mental clarity and productivity—making it the perfect tool to help get “in the zone” and stay there throughout your day. It’s has no taste so don’t worry about getting sick from the taste it’s not a lot and it is not pricey at all the value is perfect

Noticed nothing. No possitives to report

I really wanted these to have a possitive effect with my darts practice but I noticed nothing. I also wanted to have the dreams you apprently experience but got nothing. I didnt notice any possitive in any form of all day to day task. Always wanted to try these and now I have. Was really hoping these would work for me. Maybe I should try shroom tech. I like the sound of them and there benefits but am reluctant to try after my experience with alpha brain :-(

Game changer for memory loss!

[This review was collected as part of a promotion.] This product really helped with my memory and focus. I use it when I feel a little off. There isn’t any weird taste when I took it: I approve of the ingredients and the package was easy to open. Highly recommend for anyone aging and starting to lose focus and memory. It’s really helped me.

Works as advertised!

I have been struggling with staying focused in the afternoons. Alpha Brain Memory & Focus has helped keep me on task. I take a dose around 11am or so. Helps keep me going all afternoon It did take a few days to notice the effects, so stick with it. Day 3 is when I started to notice it working.

Adverse effects

I saw a lot of reviews (I think on google?) Where people mentioned they took it and had adverse effects like vomiting, headaches, dizziness etc. Their brand mentions nothing about it. I got a "trial" for really cheap so I decided to try it for myself even though I was very hesitant. It took a while to kick in but once it did I kept feeling faint, i would feel feverish on and off and eventually started vomiting. Like, could not hold my stomach at all when the feeling would come up. And eventually got a pounding headache. Would never even consider it again.

Very good

[This review was collected as part of a promotion.] I'm still on the fence about this working. It's not bad, there isn't t any side effects. I might just have to use it a little longer for it to start working. I feel a little more focused but it doesn't last long. I like the ingredients in this product. I've taken others before and this one is better than others I've tried.

Focused

[This review was collected as part of a promotion.] It’s really hard to tell if this helped or not because it is hard to tell if the change I noticed were really happening or if I was already predisposed to expect certain results. However, I can tell my attention span lasted much longer than usual since I started taking them in the past few weeks. With a longer attention span and focus, it helped me check off many tasks on my wedding planning list

Great supplements

[This review was collected as part of a promotion.] I am a big fan of these supplements, especially when I feel I need a brain boost! I will take one with food in the morning before a big day or work event, and I feel that it gives me enough energy and focus throughout the day as needed. Very easy to take and convenient to have when needed. I don’t take these all the time only when needing to have additional focus.

Definitely worth it!

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha Brain for a week now, and the difference is absolutely noticeable! These supplements are incredibly effective—they give my focus and mental clarity a real boost without any harsh side effects. One of the biggest wins for me is that there’s no bad taste or smell, which makes taking them a breeze. I felt more alert and mentally sharp just a few days in, and that momentum has only continued. Whether it’s tackling creative tasks, organizing my thoughts, or staying in the zone, Alpha Brain has become a go-to for optimizing my daily routine. 💬 Would I recommend it? Absolutely. 💰 Worth the money? Without a doubt. If you’re looking for a supplement that actually delivers, this is it.
