Not sure

I been taking it for awhile and I am not sure if it works. The first few times I took it, I had small clarity, but after the few times I haven't noticed anything.

Not worth it.

I didn't notice any difference after a month of consistent usage. I took as recommended which meant each bottle lasted 15 days. For the expense it just isn't worth it for me.

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!

Not snake oil

I do notice a difference in how quickly things come to me when I’m trying to recall a thought. And I’ve been killing it at Wordle, seems to be working.

How do more people not know about this?

Ever seen the movie Limitless? Imagine an over the counter version of that. It’s a noticeable difference, especially the focus part. I really like it.

No noticable change

I recently went back to college and was hoping this would help with my studies. I ordered a trial bottle but unfortunately I didn't notice any changes in my focus or memory. I did start to have very detailed dreams though. Worth a shot!

Real Deal

Surprisingly pleased with Alpha Brain. I definitely have noticed greater focus, especially when my sleep hasn’t been optimal and my mind would otherwise be more cloudy.

Snake oil

Took 2 pills/ day for the entirety of the bottle. Noticed no improvement regarding cognition, rather often throughout the month I found it difficult to find the right words in conversation and experienced brain fog.

Life long Subcriber

First day I took it, I went to the gym and killed it. On a day where otherwise I wouldn't have gone at all. Removes the extra effort it takes to sometimes just get to the gym.
