Really helped me concentrate! Recommend!

[This review was collected as part of a promotion.] These supplement does work. I took for almost week bc I was getting ready for a very important exam. And I passed!!!! It did help me memorize better and concentrate better. Didn’t have any side effects even thou I am pretty sensitive to supplements. I like that it doesn’t have caffeine in it. It will definitely be my go to supplement whenever I have important exams or events to get ready for. Highly recommend!

Not good for my body :(

I took two capsules with a light breakfast. Within an hour or so I felt a little jittery, almost like a coffee buzz. A couple hours later, I had a headache and was feeling dizzy and nauseous with an upset stomach. I ended up leaving work early to take a nap. I think I have pretty low blood pressure naturally and some of the ingredients may have decreased it to the point of feeling sick. My partner took one capsule and felt slightly jittery after an hour (but not too intense) and then felt totally lucid and sharp for his presentation. He got lots of compliments and felt like his words came easily. I know everyone's bodies are different, and I'm pretty disappointed that this didn't work for me.

Helpful

[This review was collected as part of a promotion.] Pretty nice vitamin supplement. It helps me a lot with my memory loss and my lack of focus. I take it daily every morning. It doesn’t taste like anything, so you don’t have to worry about a flavor as you swallow. Nicely packaged.

Great for memory, concentration, and focus!

[This review was collected as part of a promotion.] This works great! I am in school and I work! This helps me to concentrate and focus more! This helps me to retain information also! It’s not a super big pill and I can swallow it with ease! It doesn’t taste bad at all! I definitely recommend it to all!

Supplement boosts focus

[This review was collected as part of a promotion.] I’ve received the product in exchange for honest reviews. Like any supplements, this one also was tough to tell the exact effect vs placebo effect. But there was no negative side effects and easy to take the supplement as it’s in capsule form, does not taste anything.

Would try again!

[This review was collected as part of a promotion.] I am one that does try to utilize supplements everyday - I have a regimen that covers most all items except for memory/cognition. After using this product for a couple of weeks I can say that I think in conjunction with my existing regimen my brain did feel a bit more focused . I did not notice an after taste and the only reason for 4 is that I prefer supplements that only require one tablet per day as I’m already taking 5 others daily, but this would be my only drawback.

Memory focus in a bottle

[This review was collected as part of a promotion.] I like that this supplement is caffeine free and gluten free. I do think that the pills are little big so sometimes I found it hard to swallow. I didn’t notice any sort of flavor which is nice. I will continue to take these.

Tryyyy

[This review was collected as part of a promotion.] I tried Alpha Brain, the nootropic supplement by Onnit, and noticed a real improvement in my focus and mental clarity, especially during long study or work sessions. Within about a week, I felt more alert and able to concentrate without the jittery feeling that comes with caffeine. What I appreciated most was that it didn’t affect my sleep and seemed to support smoother thinking and memory recall throughout the day. It’s made with natural ingredients like Bacopa and Alpha-GPC, and I didn’t experience any side effects. While it’s a bit pricier than some other supplements, I feel like the boost in productivity made it worth it, and I plan to keep using it.

Focused

[This review was collected as part of a promotion.] Thank you influenster! This works great! It kept me focused and alert through out my day. It doesn’t taste bad either. The ingredients are natural as well which is a plus. The packaging is appealing and I’ll be buying this in the future.

Works ok

[This review was collected as part of a promotion.] This product was ok, i didn't notice a huge change in my clarity, but seems like I had a little more energy. My tummy seemed to handle it ok. I think it's a little spendy but if it works for you then it fits it's worth it. I do think it's strange that it comes in a 2 week supply.
