What do vitamins and minerals do? Am I getting enough from the food I eat? Should I take supplements? Which ones should I take and how much? Can supplements make me look and feel healthier? Can they prevent diseases? Can they slow the aging process? The answers to these questions are not always clear-cut. There is an almost daily barrage of media reports on new studies - some suggesting that a supplement does you good, others indicating that it may be harmful. This book will help you sort fact from fiction - it's the compass you need for today's nutrition maze.
