Not working for me

Ive taken this product as recommended for 3 weeks and have felt none of the advertised benefits to my mental awareness or abilities.

Love this product

I really enjoyed this product. It did just what it says it does. I was more productive and interested in things. Would last most of the day.

Amazing Product!

Alpha brain gives me the focus I need to start my day and keep it going. I feel like my memory has improved as well as my sharpness. Great product!

Alpha

First nootropic I’ve taken. Haven’t compared to other brands but seems to keep me more awake and alert.

Great stuff

Feel focused and ready to tackle anything. Getting through the day taking care of projects without skipping around to only complete them halfway.

Nothing special

I feel quite dooped, lesson learned. It doesn't provide anything more than taking a good dose of B6 & B12 could do.

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 - sometimes it can take a few tries to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team for further assistance!

Alpha Brain increased my duration of concentration

I started taking 'Alpha Brain' about 3 weeks ago and I've noticed longer periods of concentration which helps me dramatically.
