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.

Must have!

Mental sharpness and clarity can be a struggle for anyone these days, using this product has helped me keep my edge at work and at home. Keeping up with all the constantly moving parts in life can be a struggle but this product simply increases your ability to concisely work through your day no matter how busy.

Life giving product at a true value for the member

Sam's Club friends. Always wanted to try Alpha Brain but was too cost conscious to pull the trigger until I saw it come to Sam's Club. It's got an awesome value vs. Onnit.com and excited to try it. I've taken it for 4 days now and wow. I never expected the focus and added energy that these pills have given me. Truly floored and worth the $57 investment. Bravo to the team who created this product and if you're like me and can get easily distracted...Alpha Brain is your next secret power. Run, not walk to Sam's Club and get an incredible product at a great value.

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.

I love this! I have been taking Alpha Brain for 3 weeks now. Just my daily cognitive is better with remembering things and my quick recall when talking to others is back to my old self when I was younger. I highly recommend anyone to take this if you feel you are lagging in cognitive function.
