My son is super active. We didn't get him tested for ADHD but teachers and doctors think he's on the fence with having it. I tried lots of different calming remedies that really didn't do much. Children's DHA is great! It's been about 3 days now and I have noticed an improvment in his behavior and concentration. He also just had tubes put in his ears. I don't know, maybe it's the combo, but he is really coming along. Oh yeah, it tastes terrible, but I don't think you're going to get a good tasting fish oil, so I mask it in low sugar fruit juice in the AM.
