Proceed at your risk!

[This review was collected as part of a promotion.] I’ve always been curious about trying natural cognitive enhancers so was very excited to try out these supplements. Unfortunately, this was a total miss for me and gave me a terrible headache and made me feel super dizzy, to the point I had to leave work early. Essentially, I felt very drunk (without any fun). It might have just been my body, and it’s hard to fairly judge this since everyone is different and supplements aren’t a one size fits all. I highly recommend researching the ingredients and potential interactions with other medications and/or medical conditions if you decide to try this. Proceed at your own risk!

Love this supplement!

[This review was collected as part of a promotion.] My husband and I have really been into supplements the last 5 years and he swears by anything that helps with cognitive function. I tried these and I’m blown away by how clear I feel and even my attention span is better. I love these!

🧠 brain power

[This review was collected as part of a promotion.] Brain 🧠 POWER. 💪 You know those times when you’re so into what you’re doing that you can’t think about anything else? The days when you read half a dozen chapters, write a thousand words, or finish a work assignment without looking up once (and when you do, you notice it’s suddenly dark outside). How’d you like to feel like that more often? You can. 🧠Daily Nootropic Formula 🧠 Assists Mental Clarity 🧠 Promotes Flow State The feeling of being in the zone—what some in the psychology world call “flow state”—is a result of the brain producing more alpha waves, electrical pulses that are associated with creativity and productivity. As a result, you’re able to tune out distractions, think clearly, and accomplish tasks.

Pretty Neutral

[This review was collected as part of a promotion.] When i took the 2 pills i felt nauseous and headache. When i took one pill I felt better, however i did notice my sugar was a little higher than normal and after researching. There’s an ingredient that isn’t great for people trying to control their sugar. My brother in law took it and it worked great for him!

Great product!

[This review was collected as part of a promotion.] Quality ingredients that actually work! I’ve definitely noticed an increase in my memory and focus when I take these and the improvement is significant enough to warrant these as a staple in my routine. I think the value could be a bit better though.

Avoid this

[This review was collected as part of a promotion.] This product is honestly not very good, I think this is a reach to clean up past reviews and even a lawsuit claiming it doesn’t work. Which I would have to agree with. Someone else I shared with got a headache and 0 benefits that it claims.

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!

No caffeine no jitters

[This review was collected as part of a promotion.] I love that this does not have any caffeine but yet it has great ingredients to perk you up and help your brain. I used to drink coffee and then it became too much and then I went to tea and then it also became too much so I was so happy to find a product that had all the benefits and no caffeine

Mental Focus On Point

[This review was collected as part of a promotion.] I've been using Onnit Alpha Brain for a few years now along with my husband, and when I take it I always notice a real improvement in my focus and mental clarity. It helps me stay sharp during work and feel more mentally organized throughout the day. I also like that it's made with natural ingredients and doesn't give me any jittery side effects like some other supplements. The packaging is simple but attractive to both men and women. They are fairly tasteless in my opinion. Overall, it’s been a helpful addition to my daily routine, and I’d recommend it to anyone looking for a little cognitive boost.

Good, but I need more time for effect

[This review was collected as part of a promotion.] I honestly don't feel any change mentally since taking this supplement. I don't think it's ineffective, I just need more time for the supplement to take effect. I didnt have any side effects from the supplement, and the taste or smell isn't off-putting. I find the 2 pill daily requirement pretty standard and it's less expensive then other supplements on the market. Overall, I have no negating complaints.
