More focus and concentrated 😉

[This review was collected as part of a promotion.] I've been taking the Alpha Brain Onnit capsules for over a week and I've been feeling more concentrated. I usually tend to do multiple things at the same time and I forget things but now I've been feeling more focused. The packaging maintains the capsules fresh. This daily cognitive support helps to focus, supports memory, and supports reaction time. The product retails at an affordable price. The capsules taste like herbs.

Perfect brain supplement for anybody and everybody

[This review was collected as part of a promotion.] As a student, sometimes homework is not fun and exciting but this supplement helps keep me focused for longer to get everything done. The packaging is easy to use and you get your moneys worth with the amount given. It doesn’t have a bad taste either like most supplements.

Feeling great with Alpha Brain!

[This review was collected as part of a promotion.] This stuff makes me feel great. I love taking it every morning. Easy to pop capsules leave no taste. A little bit pricey but this has some really good ingredients so it is well worth it! Bottle is easy to open too.

Quicker reactions and more alert - they work!

[This review was collected as part of a promotion.] I was a little weary of trying a new supplement, as I have a handful of ones I take already. I was pleasantly surprised to feel more energetic and aware after taking these. I even felt like my reaction time on the volleyball court was a bit quicker. I had seen many ads saying how great these are - so I’m glad I got to try them. I will keep using them for a few more months, especially as I go back to school for more masters credits. I would recommend trying these to see if they work for you too!

Made me feel unwell

[This review was collected as part of a promotion.] At first, I didn’t notice a difference after taking this product. But about 3 hours later I began feeling dizzy and foggy. I went on to read other reviews with this same feeling. I guess my body didn’t like this supplement, so be cautious when trying.

Focus

[This review was collected as part of a promotion.] After consistently taking this supplement for a week, I noticed a significant improvement in my ability to concentrate and reduce procrastination. They have no after-taste either, since you swallow them whole.

Great for memory, concentration, and focus!

[This review was collected as part of a promotion.] This works great! I am in school and I work! This helps me to concentrate and focus more! This helps me to retain information also! It’s not a super big pill and I can swallow it with ease! It doesn’t taste bad at all! I definitely recommend it to all!

Eh.

[This review was collected as part of a promotion.] I’m not totally sure I’m sold on this. I have been using it for a couple weeks and have noticed slight differences in my brain power. The pills are fairly large but easy to swallow. I can’t say I’d recommend since I haven’t seen my difference or improvement.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Help with focus

[This review was collected as part of a promotion.] Not too bad, i definitely saw a better level in my ability to focus, not sure about memory though, im a mom of 2 and 3 dogs and life can be pretty all over so im always forgetting and trying to remember. I will say that i wish they were a little smaller, though.

Meh

[This review was collected as part of a promotion.] I liked the packaging and design of the label. It told you what you should expect to help with the supplement. I wish it had the ingredients listed. I have no idea what was in it based on the labeling. I did take them as directed for the whole bottle. The capsules did not have any strong taste. Also they did not cause me to feel nauseous or any negative way if I took them in an empty stomach or not. I did not notice any difference in my memory, focus, or anything like that.
