Abstract. The authors assessed the use of nonvitamin, nonmineral (NVNM) dietary supplements in a college population. They found that the use of NVNM dietary supplements among college students might be higher than that of other population groups and that the types of NVNM products they use differ from those used by an older population. Of the 272 students who completed the questionnaire, 48.5% reported they took an NVNM supplement during the past 12 months. The most frequently used NVNM products were echinacea, ginseng, and St John's wort. Of the 27 students who took NVNM products to promote weight loss, 81.5% had body mass index (BMI) values in the acceptable range. Eleven of the 19 participants who reported an adverse reaction to an NVNM supplement continued to take the products despite negative effects. Users and nonusers of NVNM supplements did not differ significantly by age, ethnicity, gender, perceived dietary adequacy, or by exercise patterns. [ABSTRACT FROM AUTHOR]
