The purpose of this study was to evaluate the content and quality of information advertised on websites that market herbal weight loss supplements. The researcher completed Google,Yahoo,and Bing searches using the keywords "natural weight loss" and "natural weight loss supplements" to identify 46 websites. A content analysis was performed using a Website Data Extraction Tool,modified from Jordan and Haywood (2007). The accuracy of information was also assessed. Descriptive statistics were used to record the FDA labeling information,safety information,and "red flags" (misleading or inaccurate information). The content analysis revealed that websites posted adequate labeling information required by the FDA. Safety information: adverse reactions (27.3%),contraindications (32.6%),and drug-supplement interactions (23.3%) were posted on the websites. Forty-five (97.8%) websites included "red flags." In addition,misleading weight loss expectations (23.9%) and misleading product safety claims (43.5%) were included. Thirty-four websites posted mechanisms of actions and only 35.3% of these were considered correct. Weight loss supplement websites place online consumers at risk because they provide misleading information and inadequate safety information. Consumers should analyze product claims and the sources providing the information. These results can aid dietitians in helping their patients understand the risks of consuming herbal weight loss supplements.
