Abstract

The consumption of protein supplements is increasingly part of the everyday life of adults in general and is associated with a healthier lifestyle. However, a constant lack of commitment to the quality of these products by companies poses risks to consumers’ health. Therefore, this study aims to analyze the protein content and compare it with the nutrition label of different protein supplements. This is an analytical original investigation. It was verified whether the food supplements comply with the label presented through food analysis (Kjeldahl method, ash content and moisture percentage) of the composition of various national and international brands (n=51). A total of 51 different protein-based supplements sold in Brazil were analyzed. The results showed that the protein values advertised on the nutritional label are similar to what the product has (P value > 0,05) and are within the 20% tolerance limit according to the current law. Also, there are similarities between different types of products (P value > 0,05) regarding their ash and water content. In conclusion, the nutrition facts of protein supplements reflect the reality of the bran of these products.
