[This review was collected as part of a promotion.] The Alpha Brain supplements by Onnit promise to improve memory and focus, but I'm uncertain they deliver because there's simply not enough doses in the sample bottle to get any certainty. So, while I don't want to write them off, and they could be helping some, I'm simply unable to give a more thorough review or higher rating.

[This review was collected as part of a promotion.] After hearing about Alpha Brain from Onnit mentioned on a number of podcasts, I was excited to try it. Over the last few years I’ve noticed a decline in my focus from smartphone overuse. After using Alpha Brain for a few months, I’ve noticed a marked improvement in my memory and focus. I appreciate that it doesn’t have caffeine and the pills don’t have a weird taste. Looking forward to continuing to see improvements with consistent use

[This review was collected as part of a promotion.] These worked so well, I could feel the difference. I was super focused on what I needed to get done. Ingredients are all natural. They had no taste, so that's a plus. I just wish they weren't so expensive.

[This review was collected as part of a promotion.] I tired the Alpha Brain supplement for about a week and I do believe it helped me be a little more focused than usual which definitely is helpful while working. I didn’t experience any negative side effects during my use. I can’t say it will stay a regular part of my daily supplements but I do feel like it does what it says it will do for the most part.

[This review was collected as part of a promotion.] I love this Onnit Alpha Brain memory and focus supplement. It's daily cognitive support that includes great ingredients like L-theanine and Vitamin B6. You only need 2 capsules per day, which makes it easy to take. It's also caffeine free!

[This review was collected as part of a promotion.] I loved this supplement. Through using it for a few days, i have to say i see a difference in my focus. I tend to change tasks every few minutes but with this one i can sit and do my work without interruption

I have zero experience with any nootropic and was very skeptical purchasing this product. I work in a high pressure and fast paced position for long hours and I wish I had known about this product 10 years ago. It eliminates the brain fog and gives me the edge I need to perform to my fullest. Excellent if you want to be a top producer!!
