Nutritional Supplements in Physical Exercise

In Brazil, the marketing of food supplements for sports purposes is supervised by the National Health Surveillance Agency (ANVISA). In 2005, products intended for physical activity practitioners had to be approved and registered with ANVISA before they could be marketed in the country. In the following years, this requirement was revoked and the purpose of this work is to discuss whether this measure was adequate, as well as to assess whether consumers have become more susceptible to the hundreds of misleading advertisements attributed to the physiological effects (hypertrophy, weight loss, increased strength, etc.) displayed on the packaging and marketing of supplements in stores and websites specializing in this commercial segment. We will also discuss whether these metabolic effects are possible through the consumption of these products.
