Okay focus pills

[This review was collected as part of a promotion.] I have tried this for the last few days and the pills are easy to swallow. Not much taste to them. I think they have helped a little with my focus and attention at work and home but they are quite expensive.

BEWARE -possible extreme side effects

This was a horrible experience. I took this while I was working, then maybe 60-90 mins later, I got overwhelmed with dizziness and extremely severe nausea. I couldn’t do anything but lay down and not even move for 5 more hours. Thank goodness it was a work from home day. I felt queasy and exhausted the rest of the night. I cannot imagine trying to drive home if I was at work. I don’t know how this is seriously legally available for purchase if it does this to people.

Not much difference.

[This review was collected as part of a promotion.] I’ve taken this on a few occasions recently and I’m not sure if I noticed much difference. I have taken it shortly before I had to work to possibly help focus, unfortunately I haven’t noticed much improvement. I will continue to use until the bottle is used but I’m not sure I would purchase again.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you.

Caffeine free supplements that work!

[This review was collected as part of a promotion.] Onnit’s Alpha Brain supplements are great for improved focus and mental clarity, memory recollection, while also being caffeine free. I do recommend testing out a smaller dosage first as there are some side effects (I experienced a bit of nausea). Also, make sure you are not taking this on an empty stomach!

No improvement, don't waste your money

[This review was collected as part of a promotion.] These are awful. First off, the price is absolutely ridiculous. My husband had been wanting to try these, so we both tested them. He saw no improvement, nor did I. In fact, during my time using this product, I would get extremely light-headed, my heart would race, and I felt short of breath. The only thing I was focusing on was whether or not I was going to pass out or pass away during the subsequent hours. Do not waste your money. A pen and pack of post-its are a better alternative and more cost efficient.

Does exactly what they say!

I'm a father of three and small business owner. Mentally I'm always being pulled in multiple directions at one time. Alpha brain helps a lot! Mostly I feel like I'm well rested when I'm not, my vision is great. I'm just mentally quick with this product no matter what's happening.

Okay

[This review was collected as part of a promotion.] I tried Onnit Alpha Brain hoping it would help with focus and memory during intense study days. I drink tea daily, so I’m already used to mild stimulation from things like L-theanine, which is also in this supplement. Honestly, I didn’t feel much of a difference. No side effects, which is a plus, and I appreciate the clean ingredients and that it’s caffeine-free. But for me, the effects were really subtle—maybe too subtle. I didn’t notice a big boost in productivity or memory recall. I think it might work better for someone who doesn’t already drink a lot of tea or take other calming supplements.

Pricybit helpful

[This review was collected as part of a promotion.] value seems a little pricey. pill is a little big, not bad. The taste is great. i will say memory has improved beyond what a typical multi vitamin can provide. overall i would consider the product if it were a bit cheaper. Good packaging.

Awesome!

[This review was collected as part of a promotion.] Alpha Brain is a supplement that aims to boost focus, memory, and reaction time. Its convenient capsule form fits easily into daily routines. However, individual results can vary, making its effectiveness a nuanced topic. Some users report improved focus, while others experience subtler effects. Ultimately, its value depends on whether it delivers noticeable cognitive benefits for you.

Game Changer!!!

[This review was collected as part of a promotion.] Ok so I rarely do reviews but this has to be told. This stuff is a game changer for me. I struggle very bad with forgetting things, not being able to focus. Stumbling on my words and having horrible concentration. Day 3 of using this I was at work and i swear I haven’t felt this much clarity in years. I was focused I was motivated and I was able to comprehend some new trainings for my job very quickly. I can’t put into words how much better I felt. It has given me a confidence I haven’t had in years. If you struggle like I do this is a must have!!! I’ll be taking this faithfully every day from now on.
