Alpha brains

[This review was collected as part of a promotion.] For those who are curious, it’s a caffeine-free blend made with ingredients known for their potential brain-boosting properties, including L-Theanine, Phosphatidylserine, Alpha GPC, Huperzia Serrata extract, and Vitamin B6. The formula is designed to deliver nutrients that may help create a more optimized environment for cognitive function without the crash or jitters that often come with stimulants. However, after trying it consistently, I personally didn’t experience any noticeable changes in how I felt mentally or emotionally.

Boosted my overall productivity in just a few week

[This review was collected as part of a promotion.] I received this product a month ago and have been using it everyday since. It’s been very effective and overall my productivity has gone up. There is no taste and I would agree that it has great value for the money. The ingredients are natural and what I would expect in a product for the claims they make.

I’m neutral

[This review was collected as part of a promotion.] I honestly don’t know what to say, I’m in the middle of working on my GED and this came at the perfect time for me to need some help with focus especially. Unfortunately , I can’t say I noticed any difference in my “focus, memory, or reaction time” as advertised. Maybe if I was on it for awhile it would have some effects, but I’m not sure.

Brain support

[This review was collected as part of a promotion.] Alpha Brain provides a noticeable boost in mental clarity and focus, especially during tasks that require concentration. I found that it helped with memory retention and reduced mental fatigue over time. While the effects aren’t drastic, it offers a subtle but reliable enhancement in cognitive performance.

Supports memory and focus!

[This review was collected as part of a promotion.] The Onnit Alpha BRAIN is fantastic for supporting memory and focus. This is a daily option that you can discuss with your doctor. The value for money is great, as is the taste! The packaging is easy to open and reclose. I think the product is effective as I have been able to improve my focus. The ingredients are listed on the bottle.

Very good

[This review was collected as part of a promotion.] This product sharpened my focus from the very first day. My mood is significantly more positive, and my mind feels clearer. While I wish it had a bit more impact on cognitive function and intellectual sharpness, I'm still very pleased with the results.

Jury is still out

[This review was collected as part of a promotion.] It’s hard to say if I noticed a huge difference in a fairly small window of time. I still felt like I hit my occasional afternoon slump, even while taking these. That said, I did notice I was concentrating better during virtual meetings and fighting the urge to keep my brain busy with multitasking. I feel like I need to test them a little longer to give a proper, thorough review. But they are easy to take, no upset stomach or anything like that.

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!

Alpha Brain does work!

[This review was collected as part of a promotion.] After taking these for a week, I do see a noticeable difference in all the areas it says, which are Focus, Memory, and Reaction Time. It isn't a feeling of overstimulation but a calm switch. It's easy to swallow them. So, I do think they are worth trying. The ingredients are pure so I love that.

Gave me head rushes and upset stomach…

[This review was collected as part of a promotion.] This product I did not like. It caused extreme head rushes and it caused me to feel ill. The packaging was intriguing with the colors but overall I would not buy again. It didn’t have an aftertaste like some supplements I’ve tried which is nice. Price point was affordable.

Good

[This review was collected as part of a promotion.] It really helps me stay focused and clear-headed. The taste is mild and easy to take, and I love the clean ingredients. The packaging looks great, and it’s definitely worth the price for the boost it gives!
