People take these supplements because advertising suggests that they prevent a range of medical conditions from developing. However, there is concern that people are consuming worryingly high doses of these supplements and the European Union (EU) has issued a directive that will ban the sale of a wide range of them.

The EU directive would help prevent this nightmare of pills replacing food becoming a reality.
