I am really happy with this supplement. I am already giving PS and DMAE to my child with ADHD, but this has made the additional improvement needed. She is much calmer, more focused and her grades at school have improved. Highly recommended.

I took this complex as a course. It feels like it's not a classic nootropic or stimulant. The effect is mild, without any sudden changes. In the first few days: I feel almost nothing; there's no "on" like with coffee or Alpha GPC. After 1-2 weeks: I find it a little easier to maintain focus; I'm less distracted; I feel calmer and more focused.

I gave it to the child during intense loads at school, it helps to concentrate attention and not be distracted, you need to take 2 banks for the course.
