I come across the symptom of omega-3 deficiency at web two weeks ago. The symptoms of omega-3 deficiency are acne, dandruff, dry eyes, ADD, depression, joint pain, chicken skin on the back of arms, etc., which match the symptoms my son has. So I decided to give my son fish oil just for the heck of it, and it does help my son's concentration and depression issue. Since it only has been two week, it may not show significant improvement, but it does make some difference. My son does not eat dairy products, and it helps, but not completely. Maybe omega-3 is the missing piece of the puzzle. I will keep everybody posted.
