It’s work good so far

[This review was collected as part of a promotion.] After receiving Onnit Alpha BRAIN® for testing, I discovered that I couldn’t use it because it’s not recommended for pregnant or breastfeeding women. So I sent it to my mom, who’s in her 50s, to try and help me evaluate the product’s effectiveness. And here’s what she felt after about three weeks of use: Her mind was clearer, and she could focus on her work more easily without getting distracted. Her memory also seemed a little sharper—she recalled details and names faster. My mom didn’t experience any side effects, like jitters or headaches, it wasn’t a dramatic change, but she definitely felt more alert. She said she’d continue to use it and see what happens, but so far, she’s very happy with it!”

Not hate it but also don't like it

[This review was collected as part of a promotion.] Don't see much difference but give 3 stars because it's vegetarian and taste not bad 😅 (not many vegetarian supplements) and also because I can take it but my mom got affected after taking it: <. So I don't think it can be used for all people.

Easy to use

[This review was collected as part of a promotion.] Taste is fine. Easy to swallow pill form. Highly recommend eating something when you take these as part of a well balanced diet. Most of us are vitamin B deficient and this supplement has 400%+ of your daily requirement!

Good

[This review was collected as part of a promotion.] I've been using Alpha Brain for a few weeks, and the results are noticeable. My focus and mental clarity have significantly improved, especially during work and creative tasks. It doesn’t give me the jitters like some other supplements, which is a huge plus. The ingredients seem high-quality and natural, aligning well with my health goals. I highly recommend Alpha Brain to anyone looking to boost their cognitive performance naturally

So much energy it will make you sick

I gave this 3 stars, because my boyfriend swears by this stuff. He absolutely loves it. As for me, I get massive bursts of energy, and then extremely sick. Like a feeling of a caffeine overdose. (Even though there is no caffeine) super nauseous, wretched headaches, and I am so focused on how bad I feel I don’t think the actual focus part works for me. They say it isn’t for everyone, and everyone has different effects.

I THINK I feel something…

[This review was collected as part of a promotion.] It’s hard for me to tell if I’m actually feeling something from a supplement or if i’m just experiencing the placebo effect. I also am not sure if taking a supplement for only two weeks is enough to really notice the results, which if you only purchase one bottle and you follow the directions that bottle will only last you two weeks/15 days. I definitely felt a bit different while taking them and I was able to be more productive at work and then also at home. As for my memory? 2 weeks isn’t enough to know, in my opinion. Forgetfulness is affected by so many different factors that it’s hard to gauge whether or not your memory is performing better after only 2 weeks. This is an incentivized review. I received this product in exchange for my honest review of it.

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! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

Onnit is on it!

It works

[This review was collected as part of a promotion.] Received this and it couldn’t have come at a better time! I’ve been so busy and scatter brained lately! I really didnt try this with the most optimistic view lol but I gave it a real shot, used it for 2 weeks and I can honestly say that it seems to slow my mind down in the sense that my thoughts weren’t escaping me! I wasn’t losing train of thought midsentence! Idk how it works but it does @influenster #complimentary @onnit #getonnit

Great focus

[This review was collected as part of a promotion.] Wow! I can’t believe how effective this supplement is. I have been taking them for about a week and have noticed such a change in my ability to focus. I also feel more organized for some reason. Quality ingredients, easy to swallow and no taste at all. Anyone who struggles with focusing etc I recommend giving Alpha Brain supplements a try

Beneficial but NOT needed.

[This review was collected as part of a promotion.] This product intrigued me. As a college student I’m often pounding coffee and running late. I liked the idea of these. But a few issues I had was, the pill was relatively large, and it’s expensive to buy these regularly. While I felt the improved effects, I just don’t think it’s a realistic product for myself as I already purchase multiple medications and supplements that I need. It’s worth it to try but I find it not necessary.
