Over half the population of the UK take a form of food supplement daily. Food supplements, such as vitamin c, are said to make up for a lack of nutrients in an individual’s diet. An example of this can be seen with vegetarianism. Vegetarians are recommended to take iron supplements to make-up for a lack of iron, most commonly found in meat products. Such an addition can prevent common problems associated with vegetarianism, such as anaemia. Statistics suggest that the most popular food supplement in the UK is multi-vitamins, with two thirds of people adding multi-vitamins to their diet. Iron tablets are the second most popular daily supplement. However, such supplements are not intended to replace a balanced diet.
