The vitamin industry is worth more than £400million a year in the UK alone, but what are these pills actually doing for people's health? Dr Giles Yeo aims to find out, exploring if vitamin and mineral supplements are what they appear to be and putting people's diets to the test to find out if they really need these supplements. Those he meets include a scientist in Copenhagen, whose groundbreaking research into antioxidants indicates they may not have the extraordinary health-enhancing properties that people believe, and a nutrition scientist from the University of Greenwich, who tells Giles that on average most people in the UK are meeting their vitamin requirements thorough their diet.
