Amazing focus

[This review was collected as part of a promotion.] Clearer Focus Without the Jitters I’ve been using Alpha Brain for a few weeks, and I’ve noticed a real improvement in my focus and mental clarity. It doesn’t give a caffeine-like buzz, but I feel more alert and organized—especially during work or mentally demanding tasks. What I like: No crash or jitters Subtle but noticeable improvement in memory recall. Helps me stay sharp during long days. Some value for money, great packaging

It’s helpful

[This review was collected as part of a promotion.] This product helped me a little to concentrate on my tasks at work. Although I expected more from it, it’s still useful. The taste isn’t horrible and the size is enough to swallow it. The ingredients I read are found to help with the brain, and I like that it’s caffeine free.

They work

[This review was collected as part of a promotion.] The pills are pretty big and the serving size is 2 pills so I don’t know how often I will take them just because they are hard to swallow. I will say I believe these are effective as I noticed I was more focused after taking them. It did make my teeth feel weird/it felt like I was noticing my teeth more. If there are days I need to focus more or I am feeling tired I will probably take these but these are definitely not an everyday supplement for me. My husband came to the same conclusion I did about them. Not a love but not a hate either!

AlphaBrain

[This review was collected as part of a promotion.] I wanted to share my experience with the Onnit Alpha BRAIN® nootropic formula with you. During the past month, I had the opportunity to test this world-renowned supplement known for supporting memory, focus, and clear thinking. One aspect of Alpha BRAIN that particularly impressed me is its unique formulation to promote alpha brain waves production and support acetylcholine levels, essential for optimal brain function. Unlike many other products, Alpha BRAIN is caffeine-free, making it suitable for individuals sensitive to caffeine or those who prefer stimulant-free supplements. I personally observed noticeable improvements in memory, focus, mental processing, and achieving a flow state while using Alpha BRAIN. Whether I was working, studying, or pursuing personal projects, Alpha BRAIN consistently helped me to stay dialed in and focused when it mattered most. Based on my positive experience, I would highly recommend Alpha BRAIN to anyone looking to enhance cognitive performance in a sustainable and caffeine-free way. I am genuinely impressed with the results and would not hesitate to purchase this product again.

So far so good

[This review was collected as part of a promotion.] I have been using it for about 3 weeks, the first week i didn’t notice much, but after the second week i have been paying more attention to details, more concentration at work. Let’s see in a few more weeks.

No difference in mental clarity

[This review was collected as part of a promotion.] I used the Onnit Alpha brain for two weeks. I started out with one a day then went to two a day for the 4th-14th days. Unfortunately I did not notice a difference in focus or anything. It did upset my stomach when I went to 2 capsules so I’m not sure that it is a good choice for me. The bottle also only lasts for about two weeks if you take it as recommended, so it’s not a great value. Pretty expensive for me to try it for longer. I didn’t notice a taste or aftertaste so that’s always a plus.

It works!

[This review was collected as part of a promotion.] Won’t lie , i do recommend these. 10/10. The packaging is definitely kinda cute. I tried for 25 days and they definitely showed some type of something. I was able to focus more and for some reason, it was like an appetite suppressant on some days. The value is worth it.

No noticeable difference

[This review was collected as part of a promotion.] I took two pills a day for about two weeks and didn't notice even a slight difference with my memory or overall focus. I'm not sure how long you are supposed to take them but I finished the bottle with no results.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B.
