Thanks for reaching out and leaving a review! Apologies that Alpha Brain did not work for you. Everyone reacts differently to supplementation, and it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team for further assistance!

Good stuff. It takes a week or so to start feeling effects but it is noticeable.

Oil of snake.

Felt like nothing happened. Maybe some of you get a placebo effect but I didnt.

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.

Clarity & hyper-focus

Cleared that “fog” in a day & a half. Helped promote focus on literally everything!
