melatonin? ... no I am not kidding.

Literally the worst supplement I have ever attempted to use. It functioned almost exactly like melatonin. I was passing out within 30 minutes of using this, every time, and quit after almost a week because of fear of passing out while driving.

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!

🤢🤮

After reading the bottle and it says take two capsules at a time, I felt like I was going to throw up all day. I told myself that going forward I will only take one at a time but I haven't been very eager to try it again since.

Alpha Brain

Alpha Brain is amazing! It has given me a renewed focus and eliminated “brain fog”. I was referred to this product, and very happy I took the next step and found out for myself what he was so adamant about!

It Freakin Works!

I was getting very cloudy. I’m a 57-year-old man and just assumed it was the end of days for my brain. Couldn’t think of words during conversation, couldn’t remember things. I immediately noticed a difference after starting alpha brain.

Great product..try it out first.

I could feel the affects pretty quick, within a couple of days, but, noticed I have some stomach issues the more I use it. Need to see how to balance it out with diet.

Zoned in

I found it to come on smoothly. No crazy effects but I definitely felt focused and zoned in on what I was doing. Helped a lot during long days at work.
