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.

The Focus Pill!

Alpha Brain seems to really be helping my mind focus more on important tasks and not drift off as much into wasteful time spending! Definitely loving it!

Best for your brain at any age

I started taking alpha Brain in my late 40s. As the executive assistant to a company president I always needed to be on point and be able to multitask. Now that I'm retired I count on it everyday to make sure I stay sharp. This stuff is amazing!.

Onnit is the BEST!

Best nootropic out there unless you start making your own, which is way to much work and research for me.. and I have tried. These guys make it easy and I know you can trust Onnit and their owners.

Alpha brain

I have noticed that I seem to be able to focus on a task more clearly than before taking alpha Brain. I'm actually only taking half the dose. So overall I can tell a difference. I've been taking it for about a week and a half. Would like to try some more onnit free trial products.

Nothing

I noticed no difference good or bad, I've been incorporating it into my daily routine. Sorry, you asked for it. It's it possible they just don't work for me? If course. They just might not be supplements I need.

Alpha Brain rough on gut

This stuff was rough on my gut. Made me dizzy too. I don't have any food allergies or sensitivities so it was really surprising. Took a few days break and tried again not realizing the connection and it happened again.
