Attention deficit hyperactivity disorder (ADHD) is quite common. It affects about one in 20 children and is three or four times more common in boys than in girls. Children with ADHD, which is characterized by inattention, hyperactivity, and impulsivity, are more likely to drop out of school. The drugs used to treat ADHD are often controversial and don’t work for 20-40 percent of the children that take them.
Some studies have shown that omega-3 fish oil may help with ADHD symptoms. What’s more, they’re safe and well-tolerated. However, the results of these studies have been mixed—some children get better, others get worse. We wanted to know whether these results depended on whether or not the children had enough omega-3 in their bodies to begin with.
