We became interested in studying the effect of megavitamins in children with attention deficit disorders following a report on megavitamins published in 1976.1 Our research protocol, which was developed at that time, was designed to replicate a report2 that suggested that more than 500 children had benefited "significantly with decreased hyperactivity and improved concentration and attention span which led to improved capacities for learning" with the daily use of massive doses of niacin, ascorbic acid, pyridoxine, and calcium pantothenate.
