In 1987 and 1988 a dietary survey was carried out in a representative sample of the Dutch population, under the authority of the Ministries of Welfare, Health and Cultural Affairs, and Agriculture and Fisheries. By means of a two day dietary record data were collected on food consumption and the use of dietary supplements. More than seventeen percent of the Dutch population has been using at least one dietary supplement on at least one day of the survey. Age, sex, season, social class, alternative food habits, smoking and diet are related to the use of supplements. In young persons mainly fluoride and vitamin AD preparations are used, while as age progresses a shift towards other supplements, like garlic and brewer's yeast preparations, is observed. The use of single vitamin C supplements is not related to the level of mean daily vitamin C intake from foods.
