Prior research by the National Health and Nutrition Examination Survey (NHANES) indicated an increase in dietary supplement use between the 1980 – 2000.1 Other results have yielded mixed outcomes regarding the health benefits of individual supplements or multivitamins despite frequent use by US adults. 2
|Trends in Dietary Supplement Use Among US Adults from 1999-20123|
|Design||Cross-sectional study; N= 5,556|
|Objective||To report trends in dietary supplement use among US adults|
|Methods||Participants (non-institutionalized persons living in the United States) were surveyed over seven continuous two-year cycles using data from NHANES. From this information, variables were created for use of any supplement product (n= 2,715) in the prior 30 days and use of 4 or more supplement products. In addition, data on the use of any vitamin, any mineral, and use of multivitamin/multimineral (MVMM) (defined as a product containing ≥10 vitamins/minerals) was collected.|
|Primary Outcome Measure||To evaluate trends in overall supplement use the preceding 30 days|
|Baseline Characteristics||Total Participants||Any supplement use|
|Age group, years|
|≥4 years of college||1397||866|
|Self-reported health status|
|Results||30-day prevalence of use, %|
|Adverse Events||Common Adverse Events: N/A|
|Serious Adverse Events: N/A|
|Percentage that Discontinued due to Adverse Events: N/A|
|Study Author Conclusions||Among adults in the United States, overall use of dietary supplements remained stable, use of MVMM decreased, and trends in use of individual supplements varied and were heterogeneous by population subgroups from 1999-2012.|
Supplement users reported motivations related to overall health as the main factor for supplement consumption. Use of supplements was related to more favorable health and lifestyle choices.3 The increase in supplement use among adults aligns with a growing body of research evaluating the potential beneficial effects of specific vitamins on a number of health outcomes, including fractures, cancer, cardiovascular disease, and multiple sclerosis.4
