ObjectiveThe economic boom in Saudi Arabia has prompted the use of dietary supplements in the last two decades. Our aim is to investigate the prevalence of dietary supplement use and its association with sociodemographic/ lifestyle characteristics, common attitude and behavior among Saudi female students.MethodsIn this cross‐sectional study, 534 female participants (19‐>26 years of age) completed a self‐administered questionnaire on their sociodemographic and lifestyle characteristics, perceived health status, dietary supplement use, general awareness, attitude and behavior.ResultsAmong all participants, the prevalence of dietary supplement use was 76.6% (n=409) with high level of education (p=0.002) and more physical activity (p=0.008) exhibiting a significant direct association with users as compared to non‐users. The frequency showed that beta carotene (54.2%), chamomile (54.2%), and glucosamine (53.8%) were the most preferred diet supplement in the category “when needed”. Cod liver oil (71.3%), omega 3 (68.3%), multi‐vitamins (61.5%), ginseng (60%), and vitamin A (60%), were mostly used in the category (from time to time). Multivitamins(34.4%) was the preferred choice when it comes to daily use, while, iron (15.9%) and potassium (12%) were used in the diseased category. The main reasons for supplement use were to “maintain healthy hair” and “injury and illness” (both 26.2%). Participants followed a medical prescription (79.3%) with social media as the best source (38%) of information. About (38.4%) were not aware and some disagree (30.3%) about any difference while taking supplements with or without consulting a medical professional. About (36.7%) of students lack information about side effects while, 35.0% were unaware about any health effect of dietary supplements.ConclusionsThe prevalence of dietary supplement use was high in Saudi female students and was significantly associated with sociodemographic and lifestyle factors.
