Pass

[This review was collected as part of a promotion.] Honestly save your money because these are so expensive for a placebo effect. They don’t really do anything and there is no scientific backing to tell that they work. There is also no research to back their claims. The packaging is nice but the product is just another scam in the health market.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key!Please reach out to our Customer Service team, they'd be happy to help further! -- Kristen ONNIT Customer Service Associate #getonnit

Worst experience of my life

[This review was collected as part of a promotion.] I was so excited to try this but man did it go downhill for me. I took it before we went on a camping trip without thinking. I went and got my usual mozzarella sticks for lunch and for some reason it tasted off. Then my chin started twitching excessively and I developed a lisp. I started freaking out thinking I was having an allergic reaction to the food or something but turns out it was the supplement. The excessive twitching moved onto my neck, chest, and stomach. I thought I was gonna have to rush to the ER instead of going camping. We had to suddenly pull over for me to throw up and then find a bathroom shortly after. The effects lasted all day. I was absolutely miserable. If you try this product, I recommend doing half the dose it says just in case. This honestly has me afraid to try another supplement :(

Product is very effective!

[This review was collected as part of a promotion.] I like how effective this product is. I been taking it for about two weeks now and my husband can see a difference. I’m not misplacing my phone wallet or keys as much. You swallow a pill so not much taste to it.

Double down

I read about 10-15 pages of a book every day and I usually have to re-read a paragraph here and there because I catch my self thinking about other stuff. Took two pills and read 30 pages straight through without having to re read anything. completely focused on the book and remembered most of what I read

Easy to swallow

[This review was collected as part of a promotion.] I've been taking Onnit Alpha Brain for a few weeks now, and I must say that I've noticed a significant improvement in my mental clarity and focus. As someone who works long hours and needs to stay sharp, I've found this supplement to be a game-changer. The capsules are easy to swallow, and I've experienced no side effects whatsoever. The label clearly states that it's a dietary supplement designed to support memory and focus, which aligns with my expectations. While individual results may vary, I can confidently say that Onnit Alpha Brain has helped me stay on top of my tasks and retain information better. I'd recommend giving it a try if you're looking for a natural way to boost your cognitive function. Overall, I'm pleased with Onnit Alpha Brain and would consider it a valuable addition to my daily routine.

Was hoping for a bigger response

[This review was collected as part of a promotion.] This supplement is supposed to help with memory, focus, and cognitive speed. Every person metabolizes and has different responses to everything so keep that in mind. I unfortunately did not have the huge response I was hoping for. Maybe if it was longer than 1 month or I wasn’t in the depths of taking care of young children (aka always exhausted) I’d notice more of a difference. I did appreciate that this was caffeine free so I could have this supplement and I didn’t have to worry about my caffeine intake the rest of the day. Again, everyone will have a different response to the supplement so you might have a totally different response!

it makes my day a lot brighter

I notice that I get more done while I'm taking alpha brain and I seem to have a more positive attitude as well. I went through a stressful situation I feel as if alpha brain and new mood got me through with much more ease than if i hadn't taken anything

Like I always say…

[This review was collected as part of a promotion.] It’s hard to tell if vitamins or supplements are working in such little time. I feel it take like 3-12 months to notice a difference, if any at all. Physically, I have never really noticed a difference when taking either. I did have good results from a hair supplement awhile back. I haven’t noticed any focus getting better but I’m sure it needs more time.

The best!

[This review was collected as part of a promotion.] I've tried many supplements to help me focus and none have given me results like this brand. I feel alert and full of energy. They don't have a bad after taste and the results are wonderful. Definitely a must try!
