Great product

[This review was collected as part of a promotion.] This product is great for focus and brain health. I love this product because of the ability to help you focus and think clearly. The product helps with memory, focus and reaction time which helps with daily task.

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.

Nope

Made me sick each time I tried it. I got extremely nauseated and threw up many times which included bouts of shakyness.

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!We appreciate your feedback after trying our Alpha Brain, although so sorry it wasn't a great fit for you!

I use it 6 days in the week. It works great for me

I don’t sleep well. So I take the product before working my 12 hour shift. I find myself clear mind and ready within 45mins from taking 2 pills.

Not a fan

[This review was collected as part of a promotion.] I tried the Onnit Alpha BRAIN supplement for several days, but didn’t feel much more focused than usual. It made me feel somewhat jittery and not quite like myself. Would not recommend.
