Effective, but not cheap

The product had the advertised effects--I was able to stay super focused for hours at a time. Unfortunately, the price is a bit steep for a student to afford and I had difficulty falling asleep after a few days.

Well worth trying

I definitely could remember where I would put my phone or the clicker for the t.v. I was loosing my mind forgetting where I just put something down. For the 30 day trial I felt much better mentally. Slow down and make sense.

Pleasantly Surprised With the Results So Far

Honestly? I am surprised to say that since I've started taking this, I've been more focused when I'm needing focus, and have more willpower to start new tasks that I otherwise wouldn't.

I was a skeptic

I go into everything skeptical, but hopeful. After about 4 days I noticed my memory recall was incredible. I was also having an easier time talking with people. I’ll definitely be buying more.

Onnit Memory and Focus

Was skeptical at first if I was feeling a bit of a placebo from taking this but after continued use it’s clear that this stuff really works. No jitters either just pure mental clarity and focus.

Good Results

I liked this as a supplement. I didn’t find the results to be as noticeable as the ads suggest but I could tell a slight difference. Perhaps I need more time with it. The good news is there isn’t a jittery side effect.

Solid product.

Happy with it so far. Keeps me focused and energized without making me jittery. After a few weeks I can definitely tell the days when I forget to take it.

From a construction worker (foreman) point of view

Works and works well... I'm an Elevator Constructor... I take Aplha Brain everyday... Idk if it's super bad but 2 worked at 1st... Then I had to take 3 every morning, and 3 has worked consistently for months now!

Almost there

I can honestly say I was skeptical. I can honestly say it helps but not in the extreme way advertising says it does. So, in reality its a good product but not great. If the formula was a little stronger that would be worth the money.
