I have seen fish oil benefit many children and adults with ADHD. It can improve focus and decrease hyperactivity and impulsivity. For some kids, these benefits become apparent within days, but for others, the benefits take much longer to become evident. Some people with ADHD do not seem to derive any obvious benefits from fish oil, or the benefits are too subtle to measure.
