Vitamania: The Sense and Nonsense of Vitamins

Almost one billion of us take a regular dietary supplement, mainly vitamin tablets. Vitamins are enthusiastically endorsed by celebrities, and vitamin-fortified foods line our supermarket shelves. But how safe are these products? Is it true that vitamins are "natural" and therefore can't do you any harm? How are they regulated, and how can parents make the right choices for their children's health. These surprisingly urgent questions are investigated by scientist Dr Derek Muller in Vitamania, the latest documentary made by Emmy AWard-winning Australian filmmakers, Genepool Productions.
