PurposeTo study the consumption pattern, attitude and knowledge of the general population about dietary supplements (DS) in the United Arab Emirates (UAE).Design/methodology/approachA community-based cross-sectional study was conducted to collect data on knowledge, attitude and consumption pattern related to the use of DS. Participants aged = 18 years were asked to complete a self-administered online questionnaire that included demographic characteristics, health and lifestyle information, consumption patterns, attitudes and knowledge levels regarding the use of DS.FindingsA total of 207 individuals participated in the study, and 117 (56.5%) participants reported using DS products as influenced by the pandemic of coronavirus disease 2019 (COVID-19), of which 63 (53.8%) participants had been using DS for more than one month but less than one year. The majority of the participants was females (64.7%), non-UAE nationals (60.9%) and employed (51.7%). Multivitamins (77.8%) were the most commonly used DS. Use of DS was more prevalent among older participants (n = 78 (61.9%), p = 0.006), non-UAE nationals (n = 79 (62.7%), p = 0.025) and employed (n = 69 (64.5%), p = 0.023). Improving general health (76.1%) and immune booster (47%) were the most frequently identified reasons for using DS, which is relatable to the COVID-19 pandemic. The majority of study participants (72.12%) reported knowing relatively little about the use of DS. About 154 participants (74.4%) did not know that DS products do not treat diseases.Research limitations/implicationsFurther studies with a larger sample size need to be conducted to examine the association between gender or chronic disease and the consumption and type of DS products used to fill the gap in the literature and overcome the limitations identified in this study.Originality/valueThis study highlights the need for community education programs and strategies that can raise awareness of the health benefits and risks of using DS. Further studies with a larger sample size need to be conducted to examine the association between gender or chronic disease and the consumption and type of DS products used to fill the gap in the literature and overcome the limitations identified in this study.
