Not a good blend for me

[This review was collected as part of a promotion.] I did not notice any memory or focus affects but I did feel nauseous even though I took with food. It doesn’t have a strong taste but I think I may have a sensitivity to something in it because all it did was make me feel nauseous.

Get on it

[This review was collected as part of a promotion.] What a great natural alternative to chemicals. I am staying focused without harsh chemicals being put into my body. This is the first time using natural mushroom as a way to manage staying on track. A great value and simple packaging.

Great supplement

[This review was collected as part of a promotion.] I have been taking this supplement for about a month and although it’s not a very long time I did notice some improvement, I tend to stay on the task and increase my work productivity. Pills do not have any taste, so it’s a plus.

Daily Cognitive Support

[This review was collected as part of a promotion.] I've been using Alpha Brain for a while now, and it has quickly become one of my favorite daily supplements. The packaging is compact, and it contains 30 capsules, making it easy to integrate into my routine. What I love most about Alpha Brain is its ability to support focus, memory, and reaction time. I've definitely noticed improvements in my productivity, especially when working on tasks that require a lot of concentration. It's not an instant "boost," but more of a subtle sharpening of my mental clarity over time. The capsules are easy to swallow, and I haven't experienced any negative side effects. It's great to know that it offers cognitive support without relying on stimulants like caffeine, which is a big plus for those who are sensitive to that. Overall, Alpha Brain has helped me stay on top of my game, whether it's at work, during study sessions, or just trying to stay mentally sharp throughout the day. Highly recommended if you're looking for a natural way to enhance cognitive performance!

Great focus and productive!

[This review was collected as part of a promotion.] This is the first time I've tried Alpha Brain after hearing about it from so many people. I absolutely am having a great experience with it. My focus is fantastic. I feel great, and am getting everything done in a timely manner. I highly recommend this. Using instead of an energy drink.

Effective

[This review was collected as part of a promotion.] I find that this product is effective for me. I take this while studying and also before training and “exams” and I performed well in my scores. No joke! Be careful not to take this too late in the night because this will keep you awake. Just take this during the day. I’m surprised I haven’t gotten curious about the ingredients. If I know more I may or may not want to take this anymore. Packaging is clear and good, not that impressive. There is no aftertaste and yes, it is a good value. I will purchase again.

It really works....

First I was very skeptical because my wife and I have tried several types of focus and energy supplements. None of them have worked. Then started seeing alot about your product and decided to give it a try. Man I can't believe it but this stuff is amazing. Day one couldn't sit down all day kept me going and brain function was on point. Only on day three and can say this is an amazing product and works. Thank you and we will be loyal customers. Thanks Joe this stuff is amazing...

You can feel the difference

[This review was collected as part of a promotion.] I added this product everyday to my daily supplement routine for 30 days. I noticed that I was able to be more focused, remember things better, and slower to over react. I really feel like this product helped make a positive difference! No taste and a great value for your money.

I really wanted it to work.

I heard of alpha brain in the JRE podcast for a while now, so I decided to try it. Unfortunately I did not feel a difference. I took 2 pills a day for 15 days and I did not have lucid dreaming or any effect at all. The only thing that I felt was one day at work I was really focused but I don't think it was alpha brain because I could not recreate that focus with this supplement. I would like to keep trying it but it's a bit expensive to buy twice a month. I really wanted it to work.

Best thing out there 10/10

[This review was collected as part of a promotion.] Been drinking it for two weeks and I can say this really works from the focus and alertness that I need to concentrate on my job. Doesn’t have a taste at all. The price very reasonable for the quality of the ingredients. Classic bottle.
