Abstract
Dietary supplements (DSs) are typically used by the elderly in a population, but younger age groups are increasingly purchasing these products. In consideration of this issue, the present study investigated the DS-related behaviors and general lifestyles of university students in South Korea. The health conditions, consciousness, involvement, and knowledge, as well as the future behavioral intentions, of DS users and non-users were determined and compared. A survey was administered to the respondents, and measurements were adapted and rephrased to suit the Korean context. Results showed that although the behaviors of DS users and non-users were characterized by similar patterns, significant differences in health involvement and future purchase were found between these groups. Health involvement influenced DSs buying intentions in the future, but no significant differences in the other variables were found. The findings suggested that university students take DSs regardless of their expectations about their efficacy and that their knowledge does not affect their intention to purchase such products.

Summary
Increased life expectancy encourages individuals to lead healthy lives, or perhaps healthy lifestyles allow individuals to have extended life expectancy. People have shown interest in how to pursue a wholesome manner of living and engage in exercise and consume healthful food, including dietary supplements (DSs) [1]. These products are used by an average of 50% of adolescent populations in developed countries, with consumption in the US and the UK being especially high [2]. 54% of American adults use DSs such as multivitamins and minerals [3]. The market for DSs has rapidly increased since 2009, reaching a size of US$1792 million in 2013 [5] In the Korean context, about 42% of adults have taken a DS at least once in their lifetime, as indicated in the results of the Korean National Health and Nutrition Examination Survey in 2015 (KNHANES) [4].
