increased focus, mental clarity, and a slight memo

[This review was collected as part of a promotion.] You know when you need to stay focused, but your mind just won't cooperate? That's exactly how I was with a thousand things to do and my concentration fading fast. That's when I decided to try Alpha Brain from Onnit. The supplement promises increased focus, mental clarity, and a slight memory boost, in other words, everything I needed!

Took awhile to feel small difference

[This review was collected as part of a promotion.] These vitamins seem to be OK, but it took a long time for me to feel the difference. Based on the price point, I’m not sure that I would continue to use this product. I definitely enjoyed the complementary trial.

Recommended

[This review was collected as part of a promotion.] 🧠 Alpha BRAIN Review (Balanced Length): I’ve been taking Onnit Alpha BRAIN for a few weeks now, and the results are real. I feel more focused, clear-headed, and mentally sharp — without relying on caffeine. No jitters, no crash, just clean brain support. It helps me stay on task, think faster, and remember things better, especially on busy or stressful days. If you’re looking for a natural nootropic to boost mental performance, I definitely recommend trying it.

Great supplement

[This review was collected as part of a promotion.] I recieved this complimentary from Influenster and Omnit. This is a great supplement to take as it really does help with focus and having energy. This came at the right time during a stressful time in my life where everything just seemed so all over the place. I didn't have my head on right most of the time but ahen I would take this I can say I had better focus and I actually felt like I could get atuff done the way I wanted to get it done. So far I am enjoying these and definitely will continue using them.

Alpha Brain

[This review was collected as part of a promotion.] I’m well aware of this brand because of how popular it is. Simple, fool proof ingredients, affordable with a subscription and works well. You take 2 a day and get to your work! Packaged well and leaves you laser focused in getting your work done!

Did not help me

[This review was collected as part of a promotion.] These went down easy. I took only one since it’s recommended when to start with just one. I am glad I did, I had stomach cramps and found myself on the toilet. TMI sorry but these weren’t for me. I was hoping so as I was looking for something that would help me focus

No Effect Not Worth it

I gave Alpha Brain a shot for 4 full months. Did not see any results whatsoever. Absolutely no change in focus or memory. Very disappointing as I was hopeful I would feel a difference even so much so I originally signed up for subscription. I have since cancelled and will not be reordering

Made me sick-not for me

Today I took this supplement for the first time and I was really hoping it would work because how great other products are. I took the recommended dosage with a light meal and about an hour or two later I broke out in cold sweats, then stomach pains came and throwing up started. Once I finally stopped throwing up I was left with a migraine and an upset stomach. Not saying this won’t work for others because I know others who take it and it works great with them. It’s just not for me obviously. Lol. Even though Alpha Brain does not work for me I’m still an Onnit customer for their other products.

Mental supplement

[This review was collected as part of a promotion.] I received this supplement free from Influenster and Onnit in exchange for my honest review . Alpha Brain is an alternative to caffeine and other unhealthy crutches that helps to increase mental energy! It has some vitamins and Onnit's blends of extracts that together can boost memory, focus, and cognitive drive! If you're curious about how to get in a mental flow state without relying on sugar and caffeine, it's worth a try! . #nofilter #gotitfree #complimentary #free #influenstervoxbox #voxbox @Influenster #contest #review @Influenster #supplement @onnit #getonnit #alphabrain
