I bought this for my 9 year old son at the recommendation of an herbal shop employee. He was and still is having behavioral problems in school. I thought this would help him to focus on school work, and to curb attitude issues at home. Although, the cost on eVitamins was about 1/2 of what I spent originally, my son has been on the max dosage for his age for quite some time, and I don't feel it's been effective. We will probably continue to purchase items from eVitamins because of the cost, but I will not be purchasing this particular item again.
