There is increasing demand for herbal and nutritional supplements in the Middle East. This study aimed to examine the use of supplements by college students in Qatar and to elucidate users' views about them. A total of 419 college students completed a self-administered questionnaire. Almost half of the respondents (49.6%) had used supplements (ever users), with 32.7% reporting using them in the previous 6 months (current users). Of the latter, 27.7% had used herbal supplements, 56.2% vitamins and minerals and 56.9% non-vitamin, non-mineral, non-herbal supplements. Many participants considered supplements to be safer and more effective than conventional medicines. Supplements were preferred over conventional medicines for the treatment of digestive conditions and common respiratory ailments and for weight management. Educating health-care providers about the benefits and risks of supplements is imperative and will enable health-care practitioners to guide patients in making informed decisions about supplement use.
