May hit each person differently.

[This review was collected as part of a promotion.] The package was eye catching. They didn't have a taste. The ingredients were a natural source. For value, I can't agree or disagree. I didn't notice a difference in memory or focus, but reaction time was on point. I'd be willing to try again for a longer period of time to see if there's any changes .

Didn’t work for me

[This review was collected as part of a promotion.] I really liked the concept of these and the fact that they’re supposed to support cognitive functions, I just feel like these didn’t do much for me. I didn’t really feel anything happening and I didn’t feel like my memory and attention were any better.

Cognitive Support

[This review was collected as part of a promotion.] I started taking Onnit Alpha Brain daily supplements about a week ago. The idea of improving my memory and focus was beyond intriguing - and maybe too hopeful. It may just be me, but I didn't notice a dramatic difference. I received this product compliments of Influenster in exchange for my honest review. I will continue to take them until I finish the bottle. I want to be thorough in trying to support my memory and focus.

Amazing Support for Focus and Mental Clarity!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain Memory and Focus for a while now, and I genuinely wish I had started sooner. As someone who’s constantly switching gears—juggling the demands of raising young kids while managing a full plate of responsibilities—staying mentally clear and focused isn’t just helpful, it’s essential. And this supplement has truly made a difference for me. The most noticeable change? I feel sharper and more in control of my thoughts. Tasks that used to feel overwhelming or time-consuming now seem more doable. Whether it’s remembering details, staying focused through long work sessions, or reacting quickly when things get hectic, I can feel my mind keeping up instead of lagging behind. What I love is that I get all this without relying on caffeine. No jitters, no energy crashes—just clean, steady mental clarity. It’s also gluten-free, which is important for anyone with sensitivities. I take two capsules with a meal, and that simple step has become a game-changer in my daily routine. If you're feeling mentally scattered, easily distracted, or just drained by everything on your plate—I’ve been there. Alpha Brain has helped me stay clear, calm, and focused through it all, and I truly believe it can help others too. It’s more than a supplement—it’s been a daily support system for my brain, and I’m so glad I found it.

Focus in a bottle

[This review was collected as part of a promotion.] Alpha Brain is a nice cognitive supplement. It's easy to swallow a little pricy but worth it for what it does. It helped me be more focused throughout the work day and shake off some of the fog I'd been experiencing

Boosting Focus and Memory: A Week in the Life of a Busy Student and Mom

[This review was collected as part of a promotion.] As an IT student and a mother of a toddler, my days are filled with constant mental juggling. The cognitive load is intense—whether I’m remembering network ports, studying for exams, or keeping up with my little one’s energy levels. I decided to try Alpha Brain to see if it could help me manage everything a bit better. After just one week of taking the supplement, I can honestly say that while it hasn’t turned me into a superwoman, it has made a noticeable difference. I’m retaining more information during study sessions, and I’ve found it easier to stay focused on tasks until they’re completed—no small feat when you’re constantly being pulled in different directions. I researched every ingredient in Alpha Brain before starting it, and I was impressed by the science behind them. Each component is designed to strengthen brain function, and so far, I’ve felt the benefits. I would definitely recommend Alpha Brain to students, professionals, or anyone who needs to be at the top of their mental game.

Terrible only make your life worse

[This review was collected as part of a promotion.] I rarely give bad reviews to dietary supplements because I feel like they either don’t make a difference or they help in some way, but this supplement is absolutely awful!! I took two capsules during a stressful week at work hoping it would help me focus. I felt so sick in my stomach, got an awful headache, and my heart beats are off two hours later. Couldn’t get any work done and had to call in sick the next day!!! Avoid this at all cost unless you want your life to be miserable.
