Focus and motivation

[This review was collected as part of a promotion.] Within days you'll notice a difference. As the days go by you'll see more and more results. I like this product from about the 3rd day. It was then that I felt a real change in my focus and motivation. Highly recommended.

True

i just started taking this supplement along with many of my other daily vitamins i take. I used to take vyvanse and although i stopped taking those months ago i feel like these really are a natural version. The results of the reviews for these are true to me and joe rogan didn't lie!!! Expensive but idk anything about this market worth it in my opinion

Better than a cup of coffee!

[This review was collected as part of a promotion.] I’ve used Onnit Alpha Brain for about 2 weeks now, and while skeptical at first, I noticed a tremendous difference in my work performance! I usually drink coffee or matcha for that caffeine boost but it always leaves me jittery and ends with a crash. Alpha Brain gave me mental clarity and focus with no negative effects. Once I took it I was in the zone in about 30 minutes and breezing through my tasks. This doesn’t replace a good cup of coffee, but it’s definitely a clean, non caffeinated way to boost brain function. 10/10.

I can tell a slight difference!

[This review was collected as part of a promotion.] I honestly can’t tell that much of a difference from taking this! Maybe the slightest with my memory! I’m a night shift worker and this has helped with my forgetfulness! It is kinda expensive though so I’m not sure I’d buy this on my own.

So Far So Good!

[This review was collected as part of a promotion.] These omit alpha brain capsules seems to be working so no complaints here. These capsules help support memory and focus. I must admit, my focus has been off lately and these capsules seems to be helping with that. I love the fact that these capsules are caffeine free.

It's awesome!

Been taking this for a while now and I don't know how I can go back. I've always had trouble recalling words and my memory was absolute garbage. I used to forget what I was doing the moment I started and sometimes forget the point I was getting to mid conversation. After taking Alpha Brain, I find I'm sharper, more focussed and better able to remember my tasks. By all means, it doesn't make me a genius but I am finding it easier and faster to think of the word I was looking for. Now I might stumble when trying to remember something but I'll get there much quicker than before. I rarely get stumped now. It's provided that extra edge at work and carrying conversations.

Very good

[This review was collected as part of a promotion.] Since I started taking Alpha BRAIN®, I have seen an improvement in my memory and ability to concentrate. The capsules are conveniently sized and easy to swallow, and are tasteless, making them simple to consume. With ingredients like vitamin B6, herbal extracts, and amino acids, I feel like my mental clarity and focus have improved significantly. The best part is that Alpha BRAIN® is gluten-free and caffeine-free, so I can use it daily without worrying about stimulant side effects.

Great product

[This review was collected as part of a promotion.] So I got these a while ago and my husband started taking them he has been forgetting the smallest things and he feels all over the place he said these have help him come a lot he was skeptical because we have never tried anything from this brand but he said they have been working of course not over night and is not a huge change everything takes time but he feels more balanced and focus

Disappointed

[This review was collected as part of a promotion.] I really wanted to like this product especially after reading through all the benefits, details, etc. However once I got to day 4, started getting headaches and didn't feel the greatest either. So I stopped taking it. Which I was able to notice a quick difference unfortunately which was quite disappointing. Given how high of a cost this product is, I can't justify the cost.
