Appears good quality.

[This review was collected as part of a promotion.] Received Alpha Brain from Influenster for my honest opinion. The packaging is good and easy to access. The capsules are easy to swallow and don't have any bad smell or taste. They didn't cause me any negative side effects. I am not sure how to tell if they are effective. I think someone might need to take the supplement for longer. I would recommend giving it a try.

Best product on the market for better sleep and br

[This review was collected as part of a promotion.] I received from Influenster Oonit Alpha Brain to support Memory & Focus. This product has L- Theanine which helps with better brain focus and better sleep and L-Tyrosine helps with theneurotransmitters in your brain. I noticed after two weeks I was remembering more quickly, my focus was on point and my overall brain function felt quicker. I also noticed I was getting more sleep almost 6-7 hours of sleep. I definitely will be purchasing this again it’s a no brainer. 😊

Brain support

[This review was collected as part of a promotion.] Alpha Brain provides a noticeable boost in mental clarity and focus, especially during tasks that require concentration. I found that it helped with memory retention and reduced mental fatigue over time. While the effects aren’t drastic, it offers a subtle but reliable enhancement in cognitive performance.

Get ready for a focus day

[This review was collected as part of a promotion.] It’s here!!! That good vitamin that will give you a boost to your day. There’s absolutely no taste. You will need to take a lot of water with it and after taking it for about 5 days you will have a better feeling and sense of what you are doing on your daily tasks. I certainly recommend, the bottle is small and can carry it with you any where you go.

No Effect

[This review was collected as part of a promotion.] My experience was not got or bad it was just meh… unimpressed I guess you can say. I did not notice any noticeable change but maybe I need to take it for a longer time I don’t know.. The pill itself was a bit big but not fat or hard to swallow… no bad taste. I can also say I experienced no side effects with it.

reply from Onnit Customer Service

Thanks for taking the time to share your experience with Alpha Brain, although we're sorry to hear you didn't love it! We all respond to supplements differently, not only in how they affect us but how quickly they affect us. In case you haven't already, we definitely recommend taking the product for a solid two weeks before deciding whether or not it’s working for you. -- Cailee B.

Focus, Clarity, and Mental Drive Without the Crash

[This review was collected as part of a promotion.] As a researcher, focus is my priority. Alpha BRAIN by Onnit is one of the most recognized nootropic supplements, and after trying it, I can see why it’s sold over 7.5 million bottles. Designed to support memory, focus, and mental clarity, it gave me a noticeable cognitive boost especially during busy workdays or deep creative sessions. What really sets it apart is that it’s completely caffeine free, which makes it ideal if you’re sensitive to stimulants or want mental support without the jitters. With ingredients that promote alpha brain wave production and neurotransmitter support, I found myself slipping into a productive “flow state” more easily and staying focused longer. While results can vary from person to person and it’s not a substitute for sleep or hydration, it’s a solid tool in my daily productivity toolkit when I need to be dialed in.

Noticeable difference

[This review was collected as part of a promotion.] I see a significant difference with Alpha Brain in my focus. I in the morning with food to help ensure proper absorption and occassionally will take an extra capsule if I have a project or task that requires extra mental attention in the afternoon. I went from dragging through my days on 3-4 energy drinks, to blazing through them with only 1 in the morning, because I'm horrible at waking up. I feel the instant it starts working. It's like an afterburner in a jet engine just ignited. No weird tweeky, or jittery feelings, just good, clean, focused energy. I work from home so it's easy to get sidetracked and forget important details. Even in my personal life I realized I was forgetting more and more. I didn't notice any difference on the first day I took the supplements. I take them with breakfast first thing in the morning. After a few days, I realized my focus was in overdrive. So much so, that time was flying by and my work days seemed shorter, but I was getting so much work done. I don't forget much now and my overall clarity is amazing! This worked best after a few weeks of being consistent. It is great value for how many pills you get. It came well packaged

Great nootropic for focus and clarity without the

[This review was collected as part of a promotion.] I’ve been using Alpha BRAIN® for a few weeks and noticed a real difference in my focus and mental clarity, especially during busy workdays. It doesn’t give you jittery energy like caffeine, but more of a calm sharpness that helps with productivity. The capsules are easy to take and didn’t upset my stomach. I did notice it works best on an empty stomach or light meal. It’s a bit pricey, which is why I’m giving it 4 stars instead of 5—but the results are impressive overall.
