Chemists sold out of vitamin pills overnight after QED first reported the sensational results of two scientific trials: vitamin and mineral supplements apparently reduced anti-social behaviour and raised the IQ of children with less than adequate diets. This scandalised some national newspapers and expert nutritionists; but the programme also prompted new trials. Today QED reveals the findings of the latest and largest of those trials - including some surprising new discoveries and the final verdict.
