Staying focused and organized!

[This review was collected as part of a promotion.] I've been trying Alpha brain as part of my daily routine and have noticed I'm more focused and organized throughout the day. I didn't experience any significant side effects. The results weren't immediate but it seemed to build up over time with consistent use.

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!.

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.

Try it

[This review was collected as part of a promotion.] It does help focus but you should check for interactions sometimes it makes me feel a bit different or light headed so try it out and see how it can work for you

Doesn't last very long

[This review was collected as part of a promotion.] I've been taking these pills for a few days now, each dose consist of 2 pills, which are easy to swallow and I take them in the morning after breakfast or after working out. They don't feel heavy on my stomach. I have noticed a slight change. They have helped me stay more focused on my work. Since I take 2 pills daily the bottle doesn't last very Long.

Not beneficial

[This review was collected as part of a promotion.] The Onnit Alpha BRAIN personally did not make a difference in my daily living. Despite taking it consistently, I found that there was no positive effect in my brain power. I would not recommend spending money on this product.

We appreciate your feedback after trying our Alpha Brain, although so sorry it wasn't a great fit for you! Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - and sometimes it can take time to notice these effects. Regardless, glad you tried it out!
