- 4 out of 5 stars reviewVerified Purchase6/22/2025It really seemed to work extremely well for 2 or 3 weeks, then i must have built up a tolerance, because i stopped noticing it working. I took it to help me study, then test. Over all it seemed to help
Up and down.
CaptainOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase8/14/2020Actually, this product really has helped me. This doesn’t need to be a long drawn out review, but I ended up subscribing after seeing some positive effects of this supplement. Good stuff.
One time buyer turned subscriber.
Bryan HtxOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase12/13/2020Alpha Brain has been impactful for me; clear mind, improved recall and greater alertness. Chronologically, being on the more "mature" side, perhaps the positive effect is more pronounced.
Alpha Brain for a more alert brain!
ProcoacherOriginally posted ononnit.com - 1 out of 5 stars reviewVerified Purchase12/3/2020I'm wondering if you have ever experience digestion issues with this product? I'm not pointing the finger but i did have some problems that seemed to stop after ceasing the the supplement.

Everyone can respond differently to a formula like this... - 3 out of 5 stars reviewVerified Purchase2/12/2023Upset my stomach a bit which can usually handle anything. LOTS of burping and gas. In all fairness, the disclaimers warned of this side effect with some consumers.
Effective but Stomach Issues

Everyone's experi... - 4 out of 5 stars reviewVerified Purchase11/10/2023I love it but feel like it gives me a low grade headache at some parts of the day. But I am way more focused and can remember words that I feel like I was constantly forgetting.
It does work!
GinaOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase8/7/2021I really like this. At first I wasn't sure, but once it built up in my system I could tell a difference. Now I take it along with my vitamins as a part of my daily routine.
Give it a try
Tonya KOriginally posted ononnit.com - 1 out of 5 stars reviewVerified Purchase4/5/2023Didn’t notice a difference when supplementing with this product. Maybe It didn’t work due to not taking it long enough possibly due to only a trial. Don’t think I will be purchasing this additionally. I’m very intune with my body. Thank you
Didn’t work for me…

Being th... - 5 out of 5 stars reviewVerified Purchase12/20/2022I was surprised to feel the difference to be honest. It really kept me on my game throughout the day and made me feel just a little more... sharp?! It's weird, but a good weird!
It works!

Mr sleepOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase8/12/2023This product delivers as promised. I started with a trial offer and picked one up for a fellow artist, we both liked it from the start. I’ve only been using it for a couple of months and will be placing my next order soon. I recommend it.
First time to try a product like this

Alpha State of Mind
TyVanPromiseOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase8/27/2019It’s great brain food, in the sense that my mind feels more alert and in tune, lacking a stimulant like coffee but with the same feeling. Trying to become Less dependent on coffee and Alpha Brain has done that for me!
Stimulate without the Stimulant
Matt ROriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase4/8/2020The immediate impact on my memory and mental clarity was almost too good to be true. I am at a different level with my performance at work and in my personal life.
Mental clarity and dramatic memory improvement
Ryan GinleyOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase5/24/2020The product dilers what it says, after taking Alphabrain I feel more aware of my surroundings and my thoughts are more clear. Thanks Onnit for the Alphabrain supplement!
Awesome product, does what it claims
ColebearOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase11/28/2022Absolutely noticed a significant change in how I feel day to day, and it has been very positive in all ways. More focus, better energy, better mental clarity, better control of distractions.
It is all good!
Montana MattOriginally posted ononnit.com - 5 out of 5 stars reviewVerified Purchase4/30/2023I take 2 every morning after the first week I noticed I was focusing more at work, I stayed in task easier, more energy and less brain fog in the am. I also take it with Shroom tech sport great combo!
Fast and effective
Jenn oOriginally posted ononnit.com - 4 out of 5 stars reviewVerified Purchase6/22/2021I definitely feel like it did something. I guess my expectations were to high in what I thought I was going to feel. I think it’s a good product though.
