So far so good.

So far so good, I've been taking alpha brain each morning (2 capsules) and its been great so far, I spend 6-8 hours per day studying material and webinars, alpha brain gives me a nice cognitive boost and allows me to remember and retain information. The only reason I don't give it a five star rating is because you'll feel it if you don't eat before taking these supplements.

Felt effective

[This review was collected as part of a promotion.] I did enjoy using this product. I am still unsure if it was a placebo, but I did feel like my cognitive function improved after taking them. I definitely felt more focused and love the ingredients are cleaner than other brands. I think if you’re in the market for a product like this, this is a good place to start.

Life changing

I want to say I usually really don’t believe in much of these types of products because there so many out in the market.It’s hard to find someone who is honest and truthful with there products but this product was amazing because it worked right away and it has changed my life big time as far as focusing and remembering things.I Will recommend this product to anyone who needs a boost in the brain it left me speechless and with a renewed mind.

Side effects

I'll tell you what. It's only been a few weeks and they seem ok . It will take a while for full effect. There are definitely side effects for sure. I can only take 1 tab @ a time or I will get nauseous for sure. Even with a light meal. One tab and I feel gassy, burping, as if something is in my throat as well . Please advise

Will be again

I've noticed I don't have sweet cravings like I used to and I'm sleeping better. I've also noticed that I want to be more active. I haven't noticed a burst of energy like the infomercial, but I am happy with what I've received. I also didn't see one ingredient on the bottle that's on the infomercial and that's the Rhodiola. I will be ordering more

Not noticeable

[This review was collected as part of a promotion.] Unfortunately while taking this product, I personally did not notice any change. I was consistent with taking it in the morning with my other medications but my sleep did not improve and I still struggled with memory issues. However I never really noticed any side effects. Maybe with more time to use the product and maybe at a different time in my life this may help.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B.

An absolute game changer

I have been more motivated and focused that ever with this. Whether its getting chores and work done, trying to learn new skills I can totally tell the difference. Ive given many pills to family and fiends to share the great experience. Everyone noticed a difference. 10/10. Will be ordering more.

Works Miracles

I bought this product and I was a bit skeptical on how good it would actually work. I’ve always had trouble remembering things and an even harder time trying to focus on my studies but I kid you not this product has made me a whole new person! Now I can remember my a** off and study without any problem. Besides irresponsibility..

Ehhhhh

I support Onnit as a company but to be honest, this is a legit placebo effect for me personally. Maybe I need more but I’m not going to take another pill or double up the dosage. Or I can see it as I got some bunk stuff and maybe the next bottle will work like advertised.

We appreciate you taking the time to leave some feedback! Sorry to hear that Alpha Brain didn't benefit you. Every person reacts differently to supplementation, and it's not uncommon to have different experiences.

It deff works. Rogan was right.

I normally don't fall for podcast advertising or "Celeb" reviews but Rogan got me! Lol I have to say I was super impressed after just a few days on this stuff. I'm definitely more focused for sure..razor sharp focus especially when I take it w my coffee. Memory is slightly more on point. It seriously improves my mood too. drastically. I'm on my second bottle now. I highly recommend! Thanks Rogan and Crew!
