Spirulina platensis como suplemento alimentar: avaliação de rotulagem e conformidade com normas vigentes

Abstract

This study aims to evaluate dietary supplements based on Spirulina platensis, focusing on their nutritional composition and the compliance of the information declared on commercial labels with current regulatory standards. To achieve this, physicochemical analyses were carried out, with emphasis on proximate composition analysis, which included the determination of moisture, protein, lipid, carbohydrate, and ash contents. The laboratory results were compared to the values stated by the manufacturers, allowing the identification of possible discrepancies and the assessment of the accuracy of the nutritional information provided. In parallel, a labeling evaluation was conducted based on the requirements established by the Brazilian Health Regulatory Agency (ANVISA), considering both mandatory elements and complementary information. Variations were observed among product labels, particularly regarding the declaration of gluten, nutritional claims, and other elements that contribute to the clarity and safety of consumer information. It is concluded that, although the analyzed supplements mostly comply with regulatory requirements, there is still a need for greater standardization in labeling and for strict quality control, to ensure transparency and reliability in the nutritional information provided to consumers.
