Unfortunately it made me feel really sick after taking it. Though it was something I might have eaten, so I didn't take it the next day. Tried it again the following day and once again felt nauseous again.

Has worked as stated but have not personally experienced any side effects like others have stated! This is effective and why I am making a second purchase.

Alpha brain is great. My focus and memory have definitely benefited. Dreams are more vivid and easier to remember. My ability to visualize has increased considerably. And because i feel more on my game, my mood has also improved. Thanks!

only had it for a week but have not noticed a different. maybe i was expecting too much. a lot of hype for the product. but the sample size was very nice, I wished other products would offer a sample pack.

I ran out of alpha brain a month ago-went a few days without it n was literally dragging-my new order arrived n I could feel the energy right away-focus came back too! My adult son put me on to Onnit mom really glad he did!

I appreciated the free trial so I could try the product. But after a week of taking the supplement I didn't notice a big enough difference to add $30-ish dollars a month to my routine.

Can't say I notice any difference in memory or cognitive ability, so far. Its been almost 4 weeks. I am in the process of studying for a promotional exam, so I would probably notice if it did.

Awesome product. Works great for me and several of my coworkers. Personally I didn’t really notice the effects until a couple weeks in when I realized my baseline mood and level of focus were elevated far above my norms.

Surprisingly pleased with Alpha Brain. I definitely have noticed greater focus, especially when my sleep hasn’t been optimal and my mind would otherwise be more cloudy.

It was okay, not as strong as I thought it would be. I take two and still don’t feel much of a difference. Might have to try Black Label and hope it changes my mind.
