Dietary supplements, being concentrated sources of vitamins, minerals and other substances with nutritional and physiological effects, are products that supplement the normal diet. The aim of this study was to determine the use, attitudes and knowledge on dietary supplements among students of the University of Nis, paying special attention to differences in responses between male and female students. The study used the original questionnaire which was distributed to 330 students from the University of Nis. The sample was stratified by school, year of study and sex.

Two or more products were most commonly used. Multivitamins were the most widely used products. The majority of respondents adhered to the declaration (77.07%).
