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!

good product, great company

I am on my second bottle of alpha brain (90 count). I do believe it works. I feel more clear. I usually take two in the morning and begin my work, which requires a lot of research and report writing. I feel that I am sharper, and that problem solving is easier. I also have had some pretty lucid dreams now and again. J. C.

Entrepreneur must have

If you’re looking to optimize your cognitive functioning, Alpha Brain is undoubtedly worth considering. Its ability to enhance focus, memory, and overall mental acuity make it a remarkable supplement. As a business professional, Alpha Brain helps reach new heights.

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.

A banana suit, two burglars and a parrot

I work 7 days a week, 12 - 14 hours a day ( I know this speaks of a personal issue deeper than I care to get into here). I have been working like this for many years and since I started using alpha brain I felt an improvement in mental balance, mood , productivity. I have also decided to start taking one day a week off...( + 2 to intelligence). This stuff needs more studies done. Btw I am a male in my mid forties.

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!

Great product!

I have been taking this product for a while on and off. I noticed a difference between when I took it and when I didn't. It's safe to say I'm taking it consistently. It makes me feel more focused and I retain information better. I would recommend this to everyone

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.

Concentration and Focus

I would certainly recommend this product as I do notice a change when it comes to the focus aspect of things. I am able to concentrate better, put more focus to things and noticed that my speech/communication has improved in a sense that I am not so hung up on thinking of words I need to use next in a conversation, email, etc..
