It works

[This review was collected as part of a promotion.] I gave it to one of my cousins since it's for men. His feedback is really positive. He found it to help him concentrate while reading & studying heavy lectures. He hasn't tried the whole bottle, only when he needed to focus, so it's say need more time to experience it long term. No side effects so far

Best!!

[This review was collected as part of a promotion.] I’ve been trying Onnit’s Alpha BRAIN for a few days now, and I’m already starting to notice a subtle but real improvement in my focus and mental clarity. Tasks that usually feel mentally draining have become a bit easier to get through, and I feel more locked in without feeling wired or overstimulated. The capsules are smooth and easy to take—no weird aftertaste, which is a big plus for me. Taste isn’t really an issue since it’s in capsule form, but I appreciate that there’s no lingering bitterness or funky smell like some supplements can have. In terms of value for money, I think it’s fair—especially considering the quality of the ingredients. Onnit seems to have put real effort into making this a clean, well-formulated product. You can tell the ingredients are thoughtfully chosen—no unnecessary fillers, and everything is clearly labeled, which I appreciate. It gives me confidence in what I’m putting into my body. If you’re looking for a brain-boosting supplement that feels clean and natural, Alpha BRAIN is definitely worth trying. I’ll keep using it to see how it performs long term, but first impressions are strong.

Brain Booster

[This review was collected as part of a promotion.] The benefits of Alpha Brain supplements is to boost creativity and productivity. To help improve your cognitive function and mental performance. You are focused, productive and unaware of your progress until you realize how much you've accomplished! It helps me throughout the day focused and energized. The value can be pricey but it makes the cost worth it.

Idk if they actually work or possibly a placebo

[This review was collected as part of a promotion.] I would like to start off by saying these pills do not smell or taste like anything which to me is VERY important. I honestly didn’t notice a huge difference after trying these for a couple weeks but the one difference I did notice was I was able to focus on one task without jumping to 8. I don’t really think a pill could help with reaction time… idk what that claim is supposed to mean. Another claim is that it helps with memory. I feel like my memory is pretty good but at the same time I feel like I always remember things and never really thought about how much I don’t remember. Placebo? Idk. Would I buy these myself? No

Amazing alpha brain

[This review was collected as part of a promotion.] I received this onnit alpha brain free from Influenster for my review. This product is amazing and has helped with focus and clarity and it is caffeine free. I will definitely be purchasing more of this and I would definitely recommend this product

It’s okay

[This review was collected as part of a promotion.] I got a bad headache and stomach problems after taking this, but I’m not sure if it’s because of this product or not. I’m not ready to try this product again but I sure hope it works for when I’m studying

Like to see more studying

[This review was collected as part of a promotion.] ONNIT Alpha Brain Supplement I have taken this for the past two weeks and really can’t say I’ve felt any different. Of course, I will continue to take and test out, but no real changes thus far. I will say, I am the perfect candidate, as I am currently in my last semester of school and need all of the focus I can get. 👩🏼‍⚕️ 🩺 Would love to see additional studies from this brand as well.

Start with one pill, it helps with focus

[This review was collected as part of a promotion.] Alpha BRAIN definitely helps with focus and mental clarity. As someone who juggles a busy schedule with work and studying, I was looking for something to keep me sharp without relying on caffeine. This has been a game changer! The bottle recommends taking two capsules, but I highly suggest starting with just one to see how your body reacts. Even with just one, I felt a noticeable improvement in my ability to concentrate and stay in the zone. Just taking one capsule really helped with mental processing and staying engaged throughout long study sessions. They’re also pretty large so if you have trouble swallowing large pills these might not be for you. I also love that it’s caffeine-free, so there’s no jittery feeling or crash later in the day. If you’re looking for a natural way to enhance your focus, this is definitely worth trying. I’ll be keeping it in my routine!
