Not too bad

I like it, i already stay really busy but it does help me focus a little bit more, i noticed having a head ache for a little while but not so bad now. The 90 day is alot better than the 30 day

Loved this product but this batch...

this batch that i just got didnt seem to be as potent. It is usually pretty strong but this batch seemed to not be. Also, make sure to take with a meal. If you dont, you may be nauseas

1000% try it out

I definitely recognize Cognitive function has increased on the days I take alpha brain. I decided to start taking it more often just because it makes me feel like I have an extra edge in the game.

I recommend the alpha brain

I've only taken the alpha brain for 15 days. During those 15 days I immediately noticed a difference. I felt the brain fogginess go away and I noticed a bump in stamina. I definitely recommend this product.

Good stuff!

This product work! I love it. Good replacement for caffeine and the jitters. In addition, you can still go to sleep without the struggle that caffeine would give if you drink coffee late.

Study Buddy

Really dig it. It's very helpful when studying for important exams. It helped me get that boost of mental energy for long study sessions and I like it for that. I do, however, feel like I need a little more to get going at times.

No difference

I have been taking Alpha Brain for a few weeks now and have not noticed any difference. I will use the rest of the bottle but will not purchase it again.

Dose

I got a 3 month supply but the recommended dose is 2 pills a day. So if I do that than I only have 45 day dose not 90. I have taken a whole bottle and didn't notice a difference.

Alpha brain

I’ve been taking consistently for a couple weeks with no results. I plan on finishing the entire bottle and if no changes, I would like to try the black label.

reply from Customer Experience

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. Being that we're all unique individuals, it's expected that we have a range of responses, since supplementation is not one size fits all. With Alpha Brain working to help memory, focus, and processing speed - sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our customer experience team, they'd be happy to help further!

My focus and memory have definitely seen much improvements! I am very forgetful, but with alphabrain I feel a bit sharper day to day. I love this product and would definitely recommend!
