The purpose of this study was to evaluate the prevalence and type of supplements used among university students, level of knowledge in this respect, reasons to supplement their diet, and the sources for information about dietary supplements. A sample of 100 students at the American University of Beirut were surveyed through a questionnaire composed of 22 questions and divided into four sections: socio-demographic, anthropometric, dietary supplement (DS) knowledge, DS intake and reasons. Descriptive statistics were conducted to determine the frequency of respondents for each variable and appropriate statistical tests were used for associations according to variable type and data. A total of 100 participants were included in the study of which 49 (49.0%) were males and 51 (51.0%) were females. Sixty-eight participants were dietary supplement users, of which 27 (39.7%) were males and 41 (60.3%) were females. Supplementation reasons differed: 53 consumed supplements to improve energy and vitality, 22 to enhance cognitive performance, 22 to promote hair, skin and health, and 13 to prevent or treat cold. A significant association was observed between dietary supplements use and female gender (OR = 5.66, 95% CI: 1.60-20.10). No significance was found between consuming dietary supplements and smoking status, BMI, living conditions, medical condition, age, exercise, major, dietary knowledge, and side effects. More than half of the participants are dietary supplements users with females being more likely to use them. The main reason for both genders to resort to dietary supplement use is to improve their energy and vitality. © 2021 Taylor & Francis Group, LLC.
