Not bad.

Definitely not what it's cracked up to be. Did not feel anything different.

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!

NOT FOR EVERYONE

Really, really bad reaction. Rapid heart beat, dizzy and later, bad diarrhea.
