Could not tell the difference

Honestly I couldn't tell any difference between using Alpha Brain and not using it. The marketing is great, it makes you hope you can actually feel the clarity but really it had very little to no effect.

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!

Amazing

Hands down, the best product I have ever used to increase mental performance. I consult and public speak for a job, no joke, I can feel the difference whe it's crunch time.

Date

I’m not 100% positive but I think I was sent an expired bottle. It says 11/22 on the bottom of the bottle but it isn’t EXP. It’s 3 other letters I’m not sure what it means. So I haven’t tried the product yet.

Great product.

This stuff works helped me with my studies and tests. Am able to retain more info and remember more info. For those who just started I would suggest splitting the dosage.

Sharper

I try to be aware of the placebo effect, because I want things to work. But I cant deny I feel sharper on days when I take it. More aware, I dont know, there's probably a few ways to describe it.

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.

The title is fine.

I was underwhelmed to say the least. I’m not into bashing companies, but I did not see a difference at all. 15 days worth of doses does not seem nearly enough to see a difference.

Alpha Brain is a lifesaver

It works well on my memory. I might be unable to remember something but within a minute or two, I can think of it. Before, I would forget something and never be able to remember it. I would just give up trying.

Best ever !!

Best supplement I have ever taken. I run maintenance for a 510 unit property and have so many numbers and things to facilitate everyday. Alpha brain keeps me focused and on task. I cannot make it through a busy week without it.
