Determinação do teor de creatina (suplemento alimentar) e avaliação dos rótulos de diferentes marcas adquiridas no e-commerce.

Abstract

The rise in sports nutrition supplements consumption is associated with a desire to boost performance during workouts, especially regarding those which demand more physical effort. With the rise of e-commerce, buying and selling these products has become easier. Seeking to contribute to the consumers health, this project’s goal was to assess the quality of different creatine dietary supplements sold on e-commerce, through the labeling and content analysis. Six samples of creatine from different brands, sold on e-commerce, were analyzed and compared with a standard sample purchased at a compounding pharmacy. To quantify the creatine content, the Kjeldahl Method was used and for the analysis of the labels, two Checklists based on RDC nº 243/2018 and RDC nº 18/2010. After analyzing the samples, two were rejected in relation to the creatine content, which was below the limit established by RDC 360/2003, with a variation greater than ± 20%. In the labeling survey, it was observed that most labels were in disagreement with current legislation. However, sample C's label was the only one that followed all the parameters of the labeling rules evaluated in the research. Considering the results obtained, it is evident the need for a more specific inspection directed to food supplements, as well as the updating of the regulations exclusively aimed at sports supplements. It is important to point out that the scientific literature is still insufficient on the subject, even in the face of the expressive growth of this market, requiring more research in the area of quality control of sports supplements, to verify if they meet the quality and safety requirements.
