Regulatory framework for dietary supplements and the public health challenge.

OBJECTIVE: The new regulatory framework for dietary supplements in Brazil prompted this analysis of the current outlook of these products and the challenges posed by the new guidelines. METHODS: We conducted a qualitative, observational and descriptive study of dietary supplements commercialized in Brazilian online stores with the help of the Google® search tool. We considered the ingredients on the labels, the effects attributed to these products and the commercial claims used as a means of promoting them to assess the necessary changes for the legal framework in the new guidelines. Finally, with the help of a database, we compared the effects declared by the manufacturers and attributed to certain ingredients with the scientific evidence described in literature. RESULTS: In total, we purchased 44 dietary supplements from Brazilian online stores (n = 7). Of the samples studied, 34.2% could not be classified in the category Dietary Supplements, as recommended by the new regulation of the Brazilian Health Regulatory Agency due to the presence of prohibited substances; 16% of products should be commercialized as medicines. Regarding the commercial appeals, 97.7% had banned expressions. Numerous claims of effects attributed to certain products were characterized as consumer fraud because they have no scientific evidence. CONCLUSIONS: The necessary changes represent a major regulatory and production challenge due to the wide range of dietary supplements and markets, an effort that aims to protect the consumers' health. Some previous gaps in the regulatory framework were not fully solved.
