Don't feel any difference & pricey

Don't feel any difference. Quite expensive too. Finished the whole bottle by taking the suggested amount everyday and still didn't feel anything different. Could be a placebo.

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. With Alpha Brain working to help memory, focus, and processing speed - 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!

Wanted it to work...

I really wanted this to work. But I really don't notice anything since taking them. I don't notice any energy level increase or increase in attention span... I've gone through just about two bottles.

Honest Review

Didn’t Know if it was going to be the placebo effect or it actually working.Vocabulary was the first thing I noticed. My vocabulary increased on Day 1. Had less brain fog moments. Mood improved. Been recommending it to people.

No effect in 2nd order

I did not get the same effect wihh the this 2nd order as I did the first. I think it may have been a bad batch? Was going to send back but did not do it yet

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!

So-so

Had to adjust the dose to 1 capsule (I assume because I’m a 5’4” 120 girl) and it seems to work a bit, but not quite what I thought was advertised/what I was hoping for. In some cases made me more tired

Meh.....

Worked better for me than Black label. But I've never felt "laser focused" with either product. The videos to sell this are entertaining though. Good luck. I'll continue to follow and see how it works for others.

Great product..try it out first.

I could feel the affects pretty quick, within a couple of days, but, noticed I have some stomach issues the more I use it. Need to see how to balance it out with diet.

Hopefully this helps you more than it did myself

I’m not 100% happy with this product. I felt a slight improvement with my words that I’ve chosen lately but very little benefits with memory. I was really hoping to have some better outcomes.
