How do more people not know about this?

Ever seen the movie Limitless? Imagine an over the counter version of that. It’s a noticeable difference, especially the focus part. I really like it.

Finally - a supplement that works!

I am in my late 50's and I can say that I have tried several other "Brain Fog" supplements. This is the first supplement that I can endorse as making a difference. I am now a regular customer!

Works OK

It appears to increase energy levels, similar to a pre workout without the full caffeine stimulant experience. It has helped my productivity though does nothing for my penchant to procrastinate.

Functional Stoner’s New Best Friend

Added to my morning routine. Water, coffee, breakfast, Alpha Brain, and a dab. Wake but not overly baked. All the benefits of a sativa, but no cloudiness, haziness, or “what was I doing?” I’m ready to take on my day.

Good Product!

[This review was collected as part of a promotion.] The Alpha Brain supplement is good. It helps you to focus more. It also helps with your memory. The taste is not bad. I haven’t had any side effects.

Helps with ADD symptoms

Helps with focus, keeps me on track, helps with my uncontrolled ADD as cannot take stimulants. I only take as needed, it works and you don't have to take it daily to get benefits!

Renew

I feel new. I started taking onnit and after the 2nd day I was more alert at work and had more energy than I usually would. I love it. About to place another order soon.

In my opinion the product did not meet the hype

I noticed improved energy and duration. I didn't notice a difference in focus and alertness. I could have gotten the same results by using CoQ10 and ginseng, yes I'm disappointed

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. That being said, if you still aren't feeling it after 2 weeks of regular use, let us know! We're happy to 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!
