Don't miss work without it!

I have taking Alpha brain for about a year now and I honestly can say it helps me be a better speaker, podcaster, and teacher. It seems I can organize my thoughts quicker and communicate more efficiently when speaking. It's like when you are swinging a bat with a weight on it; that is normal brain function. Alpha Brain takes that weight off and the bat swings much faster. I feel my brain functions quicker and smoother.

No side effects. Noticeable Results.

Excellent product! I got the free trial as I was skeptical given the mixed reviews. I did notice a big difference day after day of taking it. I have had no side effects. I even tried skipping random days to really get a good comparison and noticed tremendous improvements in my productivity and focus when taking alpha brain.

Poor Product, Poor Business

Did not notice any results and I purchased a 30-day trial on 12/20/22, yet they automatically sent my next 30-day supply on 1/14/23 prior to being able to experience the full 30 day trial. If this is how the business is run I especially do not want to be involved nevermind the lack of seeing any results.

We appreciate you taking the time to leave some feedback! Sorry to hear that Alpha Brain didn't benefit you. Every person reacts differently to supplementation, and it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take a few tries to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team for further assistance!

Bummed by the lack of positive results

The service was great and really this was just a trial buy so I didn't pay much, just shipping. I was expecting improvement mainly with focus but didn't notice any difference. I'm a large guy so I even upped the dose once or twice and still noticed nothing. I wanted badly to like this product but just didn't notice positive results.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. Being that we're all unique individuals, it's expected that we have a range of responses, since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our customer experience team, they'd be happy to help further!

Could be better.

My only issue with this product is the price for a two week supply. I understand for the best price I would need to purchase a bulk amount, but the fact that each bottle only consists of a 2 week supply is simply not worth the price regardless. Other than that the product seemed to work as advertised.

Good the first day then tired the rest

I bought this a little less than a month ago. The first da was great I was energized and charged for the da. But upon using this product for multiple days it seemed to make me more tired as the day went on even needing a nap during my lunch hour due to being so tired. I don't know if this is normal but I would like to try new mood for sleep since this did not give me much energy and did not seem to focus any better.

Thank you for taking the time to leave us this review! We're sorry to hear that you've experienced some fatigue with Alpha Brain. It is worth considering how you're taking the product. If you are taking 2 capsules, it may be worth trying just 1 capsule, especially since you had good results on day 1. Rather, if you're interested in returning this product for a refund, please feel free to contact us at help@onnit.com or by phone at 855-666-4899 and we'll be happy to assist!

So far it works great.

It has been great so far. I'm not taking 2 pills. I'm only doing 1 pill a day. But it still does great. Gives me just the focus that I need to get all my tasks done. Now this is not an energy or caffeine drink, you still need to get off the couch and get things done. But definitely helps stay concentrated on tasks!

One of my favorites

Have cycled alpha brain on and off over the past few years and this is one of my favorites. It’s not an overbearing effect but rather something subtle that helps me with increased focus and concentration. Can really notice the effects of alpha brain when I stop taking it and the difference of no alpha brain each day when I cycle off. I prefer the instant in the morning when I wake up and will take one capsul in the afternoon. I also like that onnit makes quality products and what’s on the label is actually what is in the product as well. A bit pricey but this one is worth it to me.

Clarity!

I have been using Alpha Brain as part of daily supplementation. It has really helped me maintain focus for the tasks at hand. In addition, I travel frequently for work and find that it helps "get the cobwebs" off in the mornings after long flights and client meetings. Honestly, I am not sure how I managed without it all these years. Thanks Onnit!
