Support for Focus and Memory

[This review was collected as part of a promotion.] There are just so many distractions - do you ever feel like you can't focus? Alpha Brain from Onnit may be for you! Alpha Brain is a dietary supplement that helps support memory, focus, and cognitive processing speed. With a caffeine free nootropic blend that can help optimize cognitive function and get you in a "flow state' increasing creativity and productivity. I found that these capsules were easy to swallow and had no unpleasant taste. I took 2 per day and after a few days I did feel more focused with fewer distractions. Onnit Alpha Brain could be helpful if you need support with focus or productivity. I received this product for free from Influenster and Onnit in exchange for my honest review.

Improved my focus without any jittery side effects

[This review was collected as part of a promotion.] I’ve been taking Alpha BRAIN for a few weeks now, and I’ve noticed a real improvement in my focus and memory. It doesn’t make me jittery like coffee, and I feel more mentally sharp throughout the day. The capsules are easy to swallow, and the packaging is solid. It’s a bit pricey, but the ingredient quality seems to justify it. VERY TASTY.

Didn't work for me

[This review was collected as part of a promotion.] The packaging is good. As far as ingredients it has some good ones no side effects and tasteless. I did research it and for me, it's a bit expensive. I did not feel like it did anything to me and I took it religiously.

I didn't notice a difference

[This review was collected as part of a promotion.] The capsules are large and one dose requires capsules. Fortunately, they are easy to swallow and do not taste like anything nor leave any kind of aftertaste. Unfortunately, after taking two of them and sitting down to work, I didn't notice any difference. My work requires a lot of concentration. I have to read and write all day long and I really thought that this would help me stay focused and get things done faster. However, I didn't notice that.

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected while taking this product. We all respond to supplements differently, not only in how they affect us but how quickly they affect us. Because of this we definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you, in case this helps to know! -- Cailee B.

So far so good

[This review was collected as part of a promotion.] I like that they are caffeine free, have only been taking for a few days, so cannot really say I’ve seen a difference. I do notice that I am more focused when I do take them. Just wish they were organic!

Helpful brain boost!

[This review was collected as part of a promotion.] I received Onnit’s Alpha Brain supplement for free from Influenster and Onnit in exchange for my honest review. With two capsules a day, it helps boost focus, memory, and reaction time. This supplement offers great daily cognitive support without an awful taste or smell. The nootropic formula truly helps provide a brain boost in assisting with mental clarity and promoting a flow state. Plus, the packaging is informative and it truly is a great value for money. Absolutely recommend it!

Buyit

[This review was collected as part of a promotion.] I was a little bit skeptical of this product at first, but I can say with confidence this made a huge difference in my cognitive clarity my partner and I both took this and are 100% repurchasing and will keep this in our supplement rotation. The ingredients are clean. It doesn’t have a taste, and the packaging was just standard pill containers. I would say they’re very effective 100% worth of money.

Love love love

[This review was collected as part of a promotion.] Using Alpha Brain from Onnit has been a game-changer for me. I noticed a significant improvement in my focus and mental clarity, especially during busy workdays. Tasks that usually felt overwhelming became more manageable, and I found myself staying on track without getting easily distracted. The cognitive boost wasn’t too intense, just a subtle enhancement that helped me stay sharp and productive. It’s been a reliable supplement that I now incorporate into my daily routine. Overall, I’m really pleased with the results and would recommend it to anyone looking to enhance their mental performance naturally.

Mostly just nausea.

I got a sample pack of Alpha Brain, I noticed that the instructions said to take with a light meal so I did just that. However a few hours after taking it I began feeling some substantial nausea as well as anxiety and restlessness. I ate something else and that seemed to help the nausea. I don't seem to feel the focus and memory effects very well so unfortunately I don't think this product is for me. I'm a 23 y/o male moderately active, I'm prescribed some seasonal allergy medicine so perhaps that isn't mixing well with it. I would definitely recommend a free trial of this product to see how your body reacts to it.
