Alpha Brain

Bought the 90 ct as I wanted to really give this a fair shot as I had heard good things about it. Did not notice anything that would tell me this product did anything to help nor make me justify paying what they want for this product. Please save the canned response that you list each time.

Can't beat the O.G.

Ever since I heard about Alpha Brain (thanks to Joe Rogan), the use of a nootropic interested me. When I finally used it, I quickly noticed a difference with my writing and entering the flow state and I've been using it going on two years now. I've tried the Alpha Brain Black, but it isn't the same, or as good, and just comes in a fancier bs packaging considering the price. So, I use the original Alpha Brain, and I continue to feel the difference. I recommend Alpha Brain all the time.

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.

Alpha Brain - No effects

I tried Alpha Brain previously and it made me jittery but I loved the focus it provided. This time around I felt nothing out of the whole bottle. Still have about 10 days left of supply but some reason I’m not feeling any effects. Literally no change at all in focus.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. That being said, if you still aren't feeling it after 2 weeks of regular use, let us know! We're happy to help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Pretty Good

i'm a 40 year old man, about 6' 210 lbs. I started taking 2 pills in the morning and I felt energized and focused, right away. It lasted for about 4-6 hours, and then the intensity digressed. After a couple of days I didn't feel the same initial kick, so I upped the dosage to 3 pills (per the instructions on the bottle, based on my weight) and the intensity came back like before. I tried taking 1 or 2 before bed, but i didn't get the lucid dreams that i've heard about. I only bought a 2 week supply, but I plan on buying some more and giving it a good 8 week trial. I'll update my results.

Spare Time

I have never been able to focus this well. I am currently student teaching for my Bachelor's degree. In the first 4 weeks I lost most of my hair, in the second 4 weeks, after taking Alpha Brain, everything changed. I was able to finish the final 4 weeks with ease, and I even had spare time in the week to just hang out.

I’ve had better nootropics

[This review was collected as part of a promotion.] I’ve had better memory & focus supplements so this one was just alright. I wouldn’t say it’s worth the price tag. It tastes like normal capsule supplements do, wasn’t delightful but wasn’t so bad I couldn’t stomach it. I don’t really like the design or packaging but it does seem this brand is more aimed towards men so maybe that is why? The good thing is that it does give you some brain energy but for me personally, it wasn’t anything like extraordinary. But everyone is different and I also do take other meds/supplements that it could’ve interfered with negatively.

Legit stuff

Ive been struggling with “brain fog” for about a month. You can feel this pill kick in! First pill I felt like The Terminator as I drove down the road, scanning the environment with a new awareness. My fog is just gone with this stuff. Ive tried Irwin Naturals and even at 4 pills to 1 AB its not even close.

My Experience

One star for my personal experience, the first day i thought it was great, was noticeably energized focused and motivated. After day one (had 14 day supply) I felt as if it wasn’t doing anything positive, after a week I stopped using it. Just not for me, I believe what I felt on day one was all mental

Thanks for reaching out and leaving a review! Apologies that Alpha Brain did not work for you. Everyone reacts differently to supplementation, and it's not uncommon to have different experiences.

A-brain Doing the lords work

Taking 2 of these got rid of my 3pm grogginess. Instead of pounding coffee throughout the day these just keep me sharp. Feels like my brain is working at 100% till I hit my bed at night. A bit pricey is the only complaint and keeping me from putting it on a subscription. Good stuff regardless
