Didn't work for me

Didn't help at all. Tried to convince myself, but all it did was make my pee stink.

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 for further assistance.

Just OK

It's ok at best for me anyway. I would've liked to have had a little more alertness

Hi there! Sorry to hear if you haven't experienced the desired results from Alpha Brain! For many people, they'll see a difference within two weeks of taking the product, however for others, this could take more time just depending on the person. If you've been taking for over a month and haven't seen a change, please feel free to reach out to our Customer Experience team for further assistance!
