Not for me.

Made me feel like I was about to have a heart attack after having an energy drink. Should be warnings

Good and beneficial

Not sure that I can say it's life changing, but less fatigue each day and performance/endurance is improved.

Alpha Brain and Coffee

I love Alpha Brain. I crack two capsules open in my morning coffee. It's a great combination that gets me up, focused and ready to go in the morning!

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 worth it

Tried it for two weeks, and I could not tell any difference in my mood, motivation, focus or intellect.

Works

Very rare to find a supplement that actually works. I've been taking now for 3 weeks and the brain fog is gone and memory improved.
