Disappointed.

Noticed no difference. Have 2 days worth left and have noticed no improvement.

Not sure if it works

I wish I felt a difference. A bottle and a half in. How long does it take to start noticing?

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected while taking this product. We all respond to supplements differently, not only in how they affect us but how quickly they affect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you. After that time, if you’re still not feeling it, please feel free to reach out to us directly by emailing help@onnit.com for further assistance!
