Not Quite As I'd Hoped

I had very high hopes for this product. Unfortunately, it didn't quite work as advertised for me. I tried it three times, following as directed to take it with a light meal. Unfortunately, all it did was give me an upset stomach.

Nursing school smarts

I have found that after starting alpha brain during nursing school I am able to retain information more and stay focused and awake more while working third shift. I even got my husband taking it.

Sharpness

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!

Product delivers.

Legitimate product, innovative and original idea. Focus, mental clarity, and ease of thought computations. I highly recommend the 90 day supply. You'll want to keep taking it.

Legit supplement

Great supplement for a mental boost when you need it. Love to use it after work to make sure I’m coming home and getting my personal goals accomplished.

Honest .02

Felt like it helped get the gears spinning in my head. Even felt like I was still going strong even after the bottle went empty. Can’t wait for more to keep sharp

Sadly Disappointed

I really wanted to like this product. I was really hoping to get the advertised results, but instead I saw none of those benefits and only bad cramping and gas. Even after lowering dose. Just didn't work for me.

Improved both mood and focus

I can definitely tell a difference in both my mood and my focus. I feel calmer, able to slow down and tackle work tasks without getting frazzled or overwhelmed.
