Natural Focus Support That Actually Works

[This review was collected as part of a promotion.] Alpha Brain is a solid nootropic. I noticed better focus and mental clarity without any jitters. The capsules are easy to take and have no bad taste. The packaging looks clean and professional. It’s a bit expensive, but the quality ingredients and caffeine-free formula make it worth trying if you’re looking to boost your brain performance naturally.

A slight improvement in focus!

[This review was collected as part of a promotion.] I decided to try these in a few different settings where an improvement on memory and focus could be most beneficial. I took them at work, as well as at home to have something to compare to. I feel like I did notice an improvement in my attention span while working on data entry tasks at work, and it also seemed to be beneficial while doing a big LEGO project at my house with lots of little directions to follow. I don’t feel like it was a giant change, but was happy to give it a try. Because they are capsules there was no flavor/taste connected to them. The bottle was easy to open, and not overly large so it was small enough to toss into my bag for work.

Good but nothing mind blowing

[This review was collected as part of a promotion.] I tried Alpha BRAIN hoping for a more laser-focused potential. What I got was more like flashlight focus. It was helpful, but not exactly mind-blowing. Some days I felt sharper, like I could finally win an argument with myself. Other days? Nada. At least there were no jitters or crashes, so it’s got that going for it. This supplement is decent for a mental nudge, but for the price, I expected a little more “aha!” and a little less “meh.”

Get in the zone

[This review was collected as part of a promotion.] I like that they are caffeine free. I don’t like having jitters at work or working out. The pill is easy to swallow. They don’t taste bad like others. They are good for focus, memory and reaction time. They optimize cognitive function. Taken twice daily with a light meal.

Great product

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a little while now and really noticed the difference in my focus and memory. It helps me stay sharp and clear-headed throughout the day, especially when I have a lot to do. The capsules are easy to take and don’t upset my stomach. I also feel like my reaction time and ability to process things quickly has improved.

Big capsule

[This review was collected as part of a promotion.] I've been taking them daily for a couple of weeks and I don't notice any difference in my mental acuity. It may need more time to see actual results, but I also don't have any negative effects. The only negative I find is the capsule size. It is pretty big and recommended dosage is 2 capsules.

Natural memory help

[This review was collected as part of a promotion.] Easy to swallow caplets with no after taste. Not sure if they are working as described on the packaging because I feel you need to take them longer. I will look for them in stores to purchase in the future because I do like what they offer and the ingredients that are in them.

Mood Lift and Mental Energy

[This review was collected as part of a promotion.] Thanks @onnit and @influenster for the complimentary ONNIT Alpha Brain Daily Cognitive Support. This is a supplement intended for supporting memory, focus, and cognitive processing speed. I’ve been taking 2 capsules in the morning with breakfast for about a week now and I like the effects. It’s caffeine-free and stimulant-free so it’s not a jolt to your system to get you going, but I feel like it gives me a subtle mood lift… more positive mental energy. #complimentary #AlphaBRAIN #CognitiveEnhancement #Focus #GetOnnit
