I have been using this Noorots supplement for the past 2 month every day. I like that the size of these tablets are small and slim so didn't have any issues taking them. I'm an active person that is always on the go, I find it difficult to concentrate and switch off. Taking these Nooroot tablets has helped me to feel more alert and calm. It did take a couple of weeks to notice any difference, but the subtle change has been worthwhile
