“…Because manufacturers of about two thirds of dietary supplement products were located outside of the US, they may not be fully aware of US regulations. Since many consumers use dietary supplements to treat a disease and people who do not speak English are unlikely to have access to the health care system in the US, a higher prevalence of dietary supplement advertisements combined with claims without validation in nonEnglish media outlet can adversely affect the health of these populations [29][30][31][32].…”

Background: The prevalence of dietary supplement (DS) advertisements in non-English daily periodicals, weekly periodicals, and television in the United States is unknown. Additionally, it is unclear if the claims presented in these advertisements are validated. This study aims to compare the prevalence of DS advertisements and percent of validated claims in DS advertisements among popular English and non-English daily periodicals, weekly periodicals, and television. Methods: This is a cross-sectional study involving daily periodical, weekly periodical, and television advertisements for DS in English, Spanish, Chinese, and Korean in San Francisco Bay Area and Los Angeles Area, California, USA. Study outcomes are percent prevalence of DS advertisements, percent of claims in DS advertisements that made therapeutic claims, and percent of validated claims in DS advertisements. Claims in DS advertisements were validated by using the effectiveness rating of the Natural Medicines Comprehensive Database and/or identifying a supporting randomized controlled trial (RCT). Results: The prevalence of DS advertisements across all three media outlets were 0 % in English, 0 % in Spanish, 14.8 % in Chinese, and 11.4 % in Korean. Across all three media outlets, DS advertisements were significantly more prevalent in both Asian languages than in English (p < 0.001). None of the products identified in English media outlets made a therapeutic claim whereas 18.6 % of products identified in non-English media outlets did. None of the claims in DS advertisements had an effective rating. Only one product identified in English media outlets had supporting data from an RCT. Conclusions: Our data suggest that DS advertisements are more common in Asian language media outlets than in English and Spanish language media outlets. Given the lack of validated claims in DS advertisements, rigorous evaluations of their claims should be carried out to guide and protect consumers.

“…Nonetheless, the fact remains that millions of individuals in USA and Europe are consuming these supplements, sometimes instead of a healthy diet and conventional medical treatment, which might contain hazard trace amounts of pesticides and heavy metals, including lead, arsenic, mercury, and cadmium [1,33]. …”

“…Nearly 1 in 7 adults takes supplements regularly, and approximately 40% have taken one or more dietary supplements during their life [1]. However, despite the widespread and growing use of these over-the-counter products, insight into the potential beneficial or harmful biological effects of these compounds in humans is frequently lacking.…”

There is a high and increasing global prevalence of nutraceuticals use. This study aims to systematically review and critically appraise all available evidence to identify the factors affecting consumers' decisions in taking nutraceuticals. Questionnaire, interview or focus group studies which directly reported factors affecting consumers' decisions in using nutraceuticals were included. A thematic synthesis method was employed to synthesis the findings from the included studies. Out of the 76 studies included, the key factors identified as the most important factors motivating consumers to take nutraceuticals were the perceived health benefits and safety of nutraceuticals, as well as the advice from healthcare professionals, friends and family. The identified barriers to take nutraceuticals were a lack of belief in the health benefit of nutraceuticals, the high cost of nutraceuticals and consumers' lack of knowledge about nutraceuticals. As a chief course of recommendation for the use of nutraceuticals, healthcare professionals should strive to utilise reliable information from clinical evidence to help consumers in making an informed decision in using nutraceuticals. Future studies should explore the possible ways to improve channelling clinical evidence information of nutraceuticals to the public.
