DD saw something about this as a complimentary ttreatment. So far in my research it looks like the jury's still out, but it has some other health benefits that would keep it from being a total loss even if it doesn't do anything for the ADHD. Just haven't seen anything as far as dosage for kids. Don't want to overload him, but don't want to give him to little either.
In that same vein, he's back taking multi-vitamins & this time I got him one that has extra of the Omega (3/6?) as I know that can affect brain activity. I take supplements & can tell the difference when I haven't been taking them regularly.
