My son has mild ADD and takes a minimal dose of Focalin every day. We supplement this with a peanut butter and honey sandwich on school days using Smart Balance Peanut Butter with 1000 mg of flax-derived Omega-3’s per ounce. (Jif just came out with a competing product).
I can tell when he skips the PB&H, it works so well.
For parents who are worried about study habits and school work attention span issues, try the Omega-3 PB trick.
