I bought this product for my son when he was 11 years old (he daydreamed a lot and it was affecting his school work). After a couple of days of using it, I noticed that it wasn't taking him as long as it once did to do his homework. It was helping him to focus on one thing at a time. I also tried it and couldn't believe how much it "cleared my head". I hadn't noticed before how much my mind raced. I was calm and wasn't aggravated easily during work. It is 4 years later, and both my son and I are still using this supplement whenever we feel too distracted or stressed.
