So far, nothing.

I started using Alpha Brain two weeks ago, have been taking two pills every morning as soon as I wake up. So far, I have felt nothing. Not complaining, 'cuz I knew the product came with no guarantees, everyone's organism is different, etc., but I have experienced nothing so far.

Amazing!

As a student that's also working a full time job, I found that the retention of info in the courses I am taking was far lower than I had hoped. I tried Alpha Brain and immediately noticed a huge difference. Retention and recall are awesome both during study sessions and on tests. Love it!! Thanks Aubrey & Onnit!

Unfortunate side effect

great product in the sense of all the advertised effects like energy, running at a higher rpm, better train of thought etc but unfortunately it also gave me insomnia and was 2-3 hours of sleep a night after a couple weeks of taking it. Had to isolate what the problem was and yes it was the Alpha brain supplement... might not be for everyone unfortunately it didn't agree with me

Effective, efficient, consequence free

Alpha brain helps my brain to fire the way I feel it should in perfect health. Communication skills are significantly increased, much like how caffeine is portrayed in media, and with no negative side affect unlike a high dosage of caffeine. Serving size is 2 capsules per day but I find 1 provides a the desired effect for a shift at work.

What a Terrific Product

I've just started using Alpha BRAIN on a regular basis and let me tell you, it does wonders. My morning routine is Alpha BRAIN, breakfast, coffee, hit the road. By the time I get to work, I can feel it kicking in. It's great to be able to be clear headed and focused when you come in to work, especially when you have a Mechanical Engineering project that you have to start at 6am!

Low dose for a slight edge

It’s hard to say what it does, but I feel it’s absence on the days I forget to take one. Just a bit less “on”. I usually only take one a day and with pandemic immunity focus in mind I recently started adding a single Shroomtech pill to my daily vitamins/supplements too.

Additional trial period

I would like to try alpha brain for another month. I don’t feel 30 days is enough time to make a true testament about the product. I do feel some changes for the better but I’d like to have an additional 30 day free trial to confirm this is actually working. Thank you for your consideration, Nancy

Definitely an effective product.

I had heard about this on the Joe Rogan experience and I can say confidently that although it took a bit for me to really notice the effects they are definitely there. My memory has always been terrible, but I find the things that are actually important popping back to mind at just the right time with alpha brain. I like to play videogames a lot and honestly I feel like it makes me sharper when playing too.

Never work another day without it

I love this stuff, after the first two weeks I thought it was a gimmick, but I took a week off and that's when I really noticed the difference, I noticed I was able to focus and stay on task way more when I took it, and I know this sounds weird but my conversations seamed more fluid I wasn't stumbling over words or trying to think of how to explain things it would just come out naturally, I'm a skeptical person but after that week I'm a believer that this stuff works.

Don’t wast your money.

Didn’t work at all. First I tried the recommended dose for a week with no noticeable difference. Then increased the dosage by one pill for the next week with no noticeable difference. The following week I doubled the dosage with the same result. Bottom line this stuff (as far as I can tell) is snake oil. Don’t waste your money.

Sorry to hear if you didn't experience the results you expected with Alpha Brain! If you just took the product a couple times and noticed some difference, it may be beneficial to try for at least a solid two weeks before you decide whether or not it's working! For some people, they can tell a change after the first dose, but many others needs a little bit more time to see a difference!
