Didn’t work for me

Sorry folks but I’ve been taking Alpha Brain for a month now and haven’t experienced any help with my issues. A friend told me about it and it helped him and his mom both. See said they both had memory improvement after about two weeks of use. But it has shown me zero improvement after a month. I will not be reordering.

Excellent Product!

This works GREAT for me. I have the hardest time focusing and have what I would describe as ADD without the H. I can now keep my attention on my work and my house is actually CLEAN. One note - it doesn’t work for everyone. My husband tried it and it didn’t help him. So, not for everyone, but if it works for you, get it! Definitely worth a trial to find out. :)

No miracle but does work!

To my surprise this stuff actually works. It’s no overnight miracle but it did seem to help me with short term memory recall and the ability to come up with the right words to explain something. It also made my dreams much more vivid. It did take about two weeks to really kick in so make sure you give it a chance.

Alpha Brain

I have been considering trying alpha brain for a little while, so the free two-week trial came up at the right time. There was nothing to not like about the trial, ordering was quick and easy, and the trial bottle came quickly. Unfortunately, after taking the product for two weeks, I had no noticeable changes or benefits. I believe it may work for some, just not for me. I am glad I had the chance to try the product before committing.

Clarity and Focus!!!

I'm very happy with the results after taking Alpha Brain. I work 2 jobs and put in about 12 hours every day. My thoughts are clear and I'm able to focus on my multitasking much better when I take just one Alpha Brain. My husband says the same! Placing my second order now!

Don't Bother

It is rather expensive for what it says that it does, and in researching the "proprietary blend", find it to be woefully underdosed. I fell victim to an amazing marketing campaign, and would have purchased a different product had I the chance to go back and do it again.

This definitely works

You know those days when you wake up and you’re ready to just go and everything just clicks and flows. That’s what it feels like every morning that I have taken alpha brain. I was skeptical at first but It seems to improve my memory recall, focus and vocabulary. I highly recommend it if these are functions you’re looking to sharpen.

Alpha Brain

Decided to purchase the small bottle of Alpha Brain and give it a shot in early February. Immediately, did not notice anything substantial results cognitively. Physically, this product gave me some of the worst gas that I have ever experienced in my life. I work as a carpenter in Chicago and I was able to offend iron worker and others of the blue collar class with my flatulence. My wife took the brunt of the side effect because (according to her) the gas continued when I slept. Towards the end of the bottle I began taking three capsules at night before bed. I was able to go to sleep fast and experience very vivid dreams. The graphic nature of the dreams make this product a worthwhile buy.

Hi there! Thanks for taking the time to leave this review! For any of the products on our site, we suggest using them for a solid 2 weeks before determining whether or not the product is working for you. Although some people report seeing results after the initial dose, for most people this does take a bit more time. We're sorry to hear about the issues that you've experienced with taking this product! This is something that may potentially be resolved with lowering the dose from 3 capsules nightly to 1-2 capsules nightly. Taking 1-2 capsules nightly, may still provide the vivid dreams that you're enjoying, but lessen the bothersome intestinal effect. If you're still experiencing this issue or have any other questions, please feel free to reach out to our Customer Experience Team. We can be reached at 855-666-4899 or you can email us at help@onnit.com. Thank you!

A bit more focused

[This review was collected as part of a promotion.] I haven’t been using Alpha BRAIN long enough to know for sure, but I do think it’s helped a bit with my focus and I feel less in a fog. Plus, it doesn’t have a bad taste and didn’t upset my stomach or make me feel nauseous. So far, so good!

Expensive but effective

I typically use this if I haven't had any caffeine. Be sure to eat a snack before taking the recommended amount to avoid getting light headed or woozy. It kicks in relatively fast and works a little better than coffee with no signs of withdrawals when not taken some mornings. Opposed to the typical caffeine withdrawal headaches.
