Did the job

[This review was collected as part of a promotion.] My work day is super fast paced. I’m an attendance supervisor of an entire elementary school. I need to be locked in from beginning to end. I am the only one doing my job so it’s crucial I’m not making mistakes or getting off task. The day I started this was a half day (chaos in school world) and I was moving offices 🤦🏽‍♀️ I not only completed my work fully but also moved offices and completed every curve ball thrown at me.

Great for focus, memory and reaction time.

[This review was collected as part of a promotion.] I received this for free from influenster. Thank you so much. I’m so excited to have gotten these amazing pills. They are so effective and the packaging is very simple. The pills are easy to swallow and the ingredients are very clean ans they are also gluten and caffeine free. You get a good value for your money because it’s worth all the healthy benefits it gives to your body and cognitive. They have no taste. Just swallow the pills with any liquid. They are a little big but they slide right down with water. They are very beneficial for FOCUS, MEMORY & REACTION TIME.

Your changes killed your product

We started purchasing and using Alpha Brain 3 or 4 years ago, and we found it extremely beneficial. A bit over a year ago, you announced that you had changed the formula. Well, ever since then, we've noticed no benefit from it whatsoever, and will no longer purchase your product.

Great supplement

[This review was collected as part of a promotion.] Alpha Brain helps me focus and stay sharp. It keeps me engaged during cognitive tasks. When I feel a bit scattered, I take it before I teach or coach. Usually, two pills do the trick. As for the ingredients, here’s what’s inside: - Bacopa Monnieri - L-Theanine - Alpha-GPC - Huperzine A - Cat's Claw Bark Extract - Oat Straw Extract - Vinpocetine - Acetyl-L-Carnitine - Bacopa Monnieri Extract And the packaging typically comes in bottles with 60 capsules, designed for easy daily use.

I think it worked?

[This review was collected as part of a promotion.] The Onnit Alpha Brain has a very desirable function. The problem I encountered with it was I am not sure if it does what it claims. I think it did but while I took the entire bottle, I didn’t notice anything perform better while on it nor did I seem to perform worse once off. These are pricey for not knowing whether they are true to claims or not.

Game-changer for Focus and Mental Clarity

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha BRAIN for a while now, and it has truly made a noticeable difference in my focus, mental clarity, and productivity. As someone who juggles research, writing, and critical thinking daily, I was looking for something to help sharpen my cognitive function without the jitters of caffeine. Alpha BRAIN delivered exactly that! Within days, I felt more dialed in, able to process information faster, and experienced fewer mental fog moments. Whether I’m deep into complex problem-solving or need to stay sharp during long discussions, this supplement keeps me on point. Plus, I love that it’s made with natural ingredient and doesn’t leave me with an energy crash. Highly recommended for anyone looking to enhance mental performance in a natural, effective way!

Noticeable difference!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a few weeks, and I can definitely tell a difference in my focus and mental clarity, especially during work and reading. It’s a big plus that it’s caffeine-free — no jitters or crashes. That said, the effects aren’t instant, and it took a few days to really notice a change. I also appreciate that it doesn’t upset my stomach when taken with a light meal. Great for productivity.

Hoping to help my husband focus better

[This review was collected as part of a promotion.] I picked the Onnit Alpha Brain supplements for my husband. He’s a computer science engineer and works under a lot of stress. He often forgets things, like where he hides stuff or puts his keys, so I wanted to try something that might help his memory and focus. After taking it for a few days, I feel like it’s helping a little. He seems more focused and not as forgetful as before. It’s not a big change, but it's better than nothing. We’ll keep using it and see if it helps more over time.

Works pretty well

[This review was collected as part of a promotion.] Onnit alpha brain dietary supplement focused on memory and focus has been pretty helpful. Some days I notice an increase in my focus and memory others I don’t. I’m not sure if it’s due to just starting them or if it depends on when I take them in the morning. The bottle is easy to open and store. The pills aren’t hard to swallow and I don’t notice much of a taste with them. I drink a lot of caffeine through out the day and work so I’m happy these are caffeine free so I won’t have to cut my soda and energy drinks out.
