This study aimed to describe the supplements use, assess the knowledge and attitude towards supplements and its interaction with prescribed medication, and determine whether knowledge and attitude towards supplements could influence treatment adherence in chronic disease patients.

Most of the respondents were using supplements to maintain health (78.8%), prevent health problems (72.4%) and improve overall health (63.2%). It was found that respondents' knowledge on supplement-drug interactions were not at the satisfactory level. The treatment adherence was found not to be associated with knowledge and attitude towards supplements nor numbers of supplements use.
