Alpha brain

It has been a few weeks of taking alpha brain Mon-Friday. I have noticed a bit of a difference with information recall and focus but haven’t had a clear aha experience that I can point to as a huge difference in mental clarity.

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation 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 time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Maybe not

I only had a 15 day supple so maybe more is needed to notice a difference. But I never felt different from day to day in my focus, energy, performance, etc.

Okay, I get it now!

I’m actually surprised this is working for me. I tend to be very sensitive to vitamins and supplements. I tolerate this just fine! I feel a positive difference in my overall mental clarity and routine. THANK YOU

Cool stuff

This is one of the best nootropics I’ve taken and kicks in quickly. Make sure to take with a meal and take a two day break from taking it every week. I felt more stimulated and focused

Completely Amazed

I started taking alpha brain with skepticism. With I first few days I noticed my ability to recall information was vastly improved. I have to analyze data sometimes and usually have to think harder than since using alpha brain

Love this stuff

I'm skeptical about everything. I gave Alpha Brain a shot and I really have noticed a difference in mental clarity and cognitive thinking. I recommend it highly.

It works for me

So far I feel a huge difference in focus and memory. I'm quicker to snapping out of being lost in thought and I'm able to tackle multiple tasks at work without get flustered.

Sucked for me

Got me sick on two occasions. I waited a week after the first time (in case I was actually sick) and it still made me sick. Dizzy, nauseous, it really sucked.

test trial

did feel more focused but would have liked to know how long it takes to activate and how long before it wears off? do i spread out the doses? and does that even help.

Brain Function changes

I haven't been able to detect any improvement in my brain function after taking these supplements. Does it take several weeks before you notice a difference?

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.
