Alpha Brain tablets

My 17 yr old son uses this product, he’s in his last year of high school and is very stressed out with all the work and exams and states it helps him retain information and allows him to focus on the task at hand.

Concentrate

I get into anything and just start flowing, my mind is running on high octane. I used to smoke weed all the time and my short term memory is shot, this helps a lot with that.

It’s working!

I recently started taking this product and within a couple of weeks noticed a remarkable difference in my focus and concentration. I cannot wait to see what taking this for a couple of months doea for me.

Product didn't work for me.

The product didn't work for me. I tried it for about a week with no results and then went to the website that recommended waiting 14 days for the product to do something. So I continued to use but no noticeable difference after the 14 days.

Nothing but positives come with Alpha Brain.

Gets me focussed and ready for tasks at hand within 30mins of taking. Memory levels go up, as does my abilities to work things out logically. Love taking it before a workout, extra boost I need to be able to focus on the workout and results.

Very affective

[This review was collected as part of a promotion.] Very affective. I felt like I had mental clarity and could focus on things without being overwhelmed. I did not feel like I had any caffeine jitters.

Wish I had a bigger bottle

It actually works 10 or 15 minutes you will feel the actual changes happening you will be focused for about 4 to 6 hours. And you can get everything done. You really want to get done mentally. It's kickass

Would like to try again

I heard mixed reviews on alpha brain prior to trying it. Once I tried it, I couldn't discern whether it was a placebo effect or not, but I did feel the desire to learn something, read a book, etc...I did not see an improvement in my focus or memory
