Walk down the aisle of any supermarket or pharmacy and you are bound to be confronted by shelves full of nutrient supplements, from vitamin A to zinc. But are they worth the staggering prices many people pay for them? What exactly are supplements, and when should they be avoided? This program looks at a wide range of supplements that are currently available and examines their potential impact on elderly consumers, high performance athletes, and pregnant women. Also spotlighting issues of product labeling and celebrity endorsement, this is a much-needed look at an industry which, despite public concerns, is only getting bigger.
