Amazing product!

Amazing product, I take the Total Human day and night packs and it's made a noticable difference in my energy and mental clarity! I would highly recommend you try it!

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.

Up and down.

It really seemed to work extremely well for 2 or 3 weeks, then i must have built up a tolerance, because i stopped noticing it working. I took it to help me study, then test. Over all it seemed to help

Waste of money

Waste of money. Been using this for about 2 weeks now and can’t tell a difference. Was hoping to see a boost in mental focus with this as I am a student and could really use it at times. Really disappointed and will never buy again.

We appreciate you taking the time to leave a review about your experience with Alpha Brain! So sorry you didn’t have the experience that you were hoping for. While we do typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot regardless. -- Cailee B.

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!

Alpha Brain!

This stuff is amazing! When I have big projects coming up, I know I need to be consistent with Alpha Brain and exercise. This makes me the best version of myself with clear thoughts and ready for action!

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!.

No noticeable results

Used the black label as directed untill entire bottle was gone. I have nothing negative to say. But I had no noticeable results unfortunately. I wish I could give a better score but as I say I didn't see anything.

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.
