Not exactly what I was hoping for.

[This review was collected as part of a promotion.] I was super excited to try this out; but unfortunately it didn't deliver the results I was hoping for. The only thing I really noticed a change in was I felt a little more alert. But not moreso than intaking caffeine without the jitters. It absolutely could be that this just doesn't work for everyone; because it unfortunately did not work for me.

Clearer focus with no jitters

[This review was collected as part of a promotion.] Alpha Brain has helped me stay sharp and focused without the crash or jitters since it’s caffeine-free. After a few days of consistent use, I began to notice I have better mental clarity. It works best with food and has become a helpful part of my routine for busy days!

ONNIT ALPHA BRAIN

[This review was collected as part of a promotion.] I received this product free in exchange for my honest review. I was excited to try this product to help with memory and focusing. However, after using it for a few days, i started to get nausea and bad headaches, so I stopped using the product

Focus fine

[This review was collected as part of a promotion.] These are great! They seem to work really well as I definitely feel like I am able to focus better and get more done. Don’t like the taste but it’s easy to get past. Definitely want to see how they work long term!

Really helps with focus!

[This review was collected as part of a promotion.] I’ve been using this for almost a month now and I’m really impressed with how much it’s helped with my focus! One of its main ingredients is an amino acid called L-theanine, which is known to support brain function. It also includes a short list of other supplements that support memory, focus and reaction time. I really like the fact that it’s caffeine and gluten free! The pills aren't that big and don't have a strong taste. The packaging is nice and the bottle is easy to store. Overall, I’m very satisfied with the results so far, I highly recommend you try this yourself!

Game changer!

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!!

Effective, easy to swallow, quality supplement.

[This review was collected as part of a promotion.] The Onnnit Alpha Brain supplements are surprisingly effective! I took the recommended dose of two per day, every day until the bottle was gne (2 weeks), and by end of the first week, I found myself more focused, and my responsiveness seemed improved. I've made no other changes to diet or otherwise . I did research the ingredients and alll are safe. The supplement is also gluten and caffeine free, which I appreciate as o many supplements for brain and focus contain high amounts of caffeine. Capsules are also easy to swallow. If I didn't have a similar produt I agreed to test, I would've already purchased more of these. I was given a full size product in exchange for my honest review by Influenster.

Very effective

[This review was collected as part of a promotion.] This is a great supplement for memory and focus. It really does help you maintain focus on your everyday activities. It helps with stress and really does give you the boost your brain needs to help with memory as well.

Takes the mental fog away

[This review was collected as part of a promotion.] Now that I'm back to working two jobs, I've found that the mental fatigue is rough mid afternoon. I've enjoyed taking these supplements to keep me engaged throughout the entirety of the work day. They are easy to take and have no nasty aftertaste.
