Must have!

Mental sharpness and clarity can be a struggle for anyone these days, using this product has helped me keep my edge at work and at home. Keeping up with all the constantly moving parts in life can be a struggle but this product simply increases your ability to concisely work through your day no matter how busy.

Helps keep my energy/focus up

I take one pill after lunch and it helps keep my energy up so that I am able to study after I get home from work.

Nope

Made me sick each time I tried it. I got extremely nauseated and threw up many times which included bouts of shakyness.

I use it 6 days in the week. It works great for me

I don’t sleep well. So I take the product before working my 12 hour shift. I find myself clear mind and ready within 45mins from taking 2 pills.

Performance

I’ve taken alpha Brain previously a few years ago seeing good results but this time a round, I haven’t seen a difference in my performance yet. I’m onto my 2nd bottle taking 2 in the morning first up and 1 in the afternoon just before training. Hopefully Ill see the difference soon.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain hasn't been a good fit for you this time around. 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. Additionally, your needs can change over time. 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!

Wanted to Love it but...nothing.

Unfortunately I haven’t noticed any benefits whatsoever after finishing one bottle. Maybe it works, just didn’t work for me and certainly nothing like what I’ve heard some people describe. I wanted to Love this product but it just left me disappointed.

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!
