A little disappointed :(

I was so looking forward to trying this product with the highest of hopes but unfortunately I didn't notice a difference. It's on the costly side so I can't justify trying it for a longer amount of time.

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected. We all respond to supplements differently, not only in how they affect us but how quickly they affect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you. After that time, if you’re still not feeling it, please feel free to reach out to us directly for further assistance.

Amazing product that does work. Little Pricey.

Took a couple days to really see the difference but works as advertised. Tried other brands of similar products and do not get the same results as this one.

Blown Away!

Wow. I was struggling to recall things that used to be serving nature to me. After just a couple I of days, I couldn’t help but notice how much quicker things were getting from my brain to my mouth. I’m telling everyone to try this product.

Im sold

I purchased Alpha Brain and New Mood. Both of which exceeded my expectations. Being a skeptic overall im completely satisfied with giving onnit products some blind faith.

Solid product.

Happy with it so far. Keeps me focused and energized without making me jittery. After a few weeks I can definitely tell the days when I forget to take it.

Alpha Brain is more important to me than coffee.

I've been an Alpha Brain user for over 3 years now. I have shot over 70 episodes of TV with Alpha Brain flowing through my body. I swear by its effect on my work.

No jitters. Crash. Productivity. Great workout

Tried it for a few days. Honestly fantastic. I will say I’m pretty sensitive and 2 capsules was a little much so I went back to taking just one instead but it was great. No jitters, just focused productivity. Also feel like it helped me work out.

Good for him nothing for her

I took these two weeks and didn't feel a difference, not even after stopping taking them. My husband has been taking them about a month now and wants to continue because he does feel his mind is clearer. Great for him, not much for me.
