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.

Worth a try

[This review was collected as part of a promotion.] So I think this did help me focusing more but I think you need more than 1 bottle to really see results. I would recommend but definitely would think you need a longer trial time to see real results

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.

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

I didn’t see a change but that doesn’t mean you won’t!!

[This review was collected as part of a promotion.] I did try this product and I will say I’m not sure if it really made a difference or wasn’t effective at least for myself ! The design and durability I would say is like any other supplement I wouldn’t really say there is a texture it’s just a capsule! The quality of the brand seem very nice though and I liked the packaging!!

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!

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.
