Not for me.

Had a bad reaction to this the first time I took it as directed. I tried it again the next day just to be sure it was in fact Alpha I was reacting to. Same thing. Nauseous, dizzy, generally unwell feeling. It was progressive and lasted most of day, into the evening.

Postpartum mental relief

I am 3 months postpartum and struggle to feel like myself and get my usual amount of things done in a day when I am dealing with raging hormones and sleep deprivation but I will take Alpha brain on days I know I need to get caught up on tasks and I can honestly say my life would be a mess if it wasn’t for Alpha Brain helping me get things checked off the list.

Didn’t work for me

Did not work for me. In fact, it felt like it caused me to be scatterbrained. I tried it with a little caffeinated tea one morning and without any caffeine the next. No matter when or what I took it with, it didn’t seem to make a difference. Very thankful that I could get a small bottle to try it out before buying months worth.

Get it.

That it honestly works. I am the COO of a big company down in Vancouver Canada and I can tell you it’s changed how I operate every day. I have more focus on a single task, my decision making is quicker and better and my all around brain feels stronger. Highly recommend.

Upset gut

The product worked well, it helped me with concertation and productivity. It unfortunately made my gut upset with gas, cramps and diarrhea for multiple days after ingesting two pills in a day as described in package. It may not work well with people with gut sensitivity.

Alpha Brain works!!

I've been taking Alpha Brain for a while. It helps me alot with focusing on multiple tasks. Wether it be writing a report, studying for test, or if you need something to get me the extra mile. I take Alpha Brain instead of pounding a bunch of energy drinks or 3 cups of coffee.

Good flow

I would take it first thing in the morning and it would get my day going at 100% ! The effect is gradual, but noticeable, to the point where I only had to drink one cup or less of coffee (vs 2-4). I am curious to understand how this stacks up against the black label version.

Unfortunately, it didn't come close to work.

Unfortunately, while I really wanted this product to work, it doesn't even compare to Mind Lab Pro, a nootropic which gives the results I really wanted when it comes to focus and memory. It also gave me nausea and headaches, even after consulting with a doctor. Hope it works for other people, but it didn't come close for me.

Wait... what??

Literally a waste. Had high hopes, really was hoping this would work but nope.... I’m sure I’m benefiting (from some of the ingredients as far a supplements go) but I do not feel any of the effects it claimed you would feel when taking this supplement daily as directed.

Execution at work improved immensely!

Improved my memory and focus, like it said it would, which is imperative for my line of chaotic work. I felt like I could organize my priorities in my head quickly and without having to dwell on them. It feels like a wave of clarity throughout my day. Almost like the capacity to organize a ton of thoughts at once has become innate. My vocabulary has improved. I don't forget words for certain things. I feel like I'm functioning at a higher level. And I had my doubts!!!
