The Chamber of Deputies’ working group on the marketing of dietary supplements will hold a public hearing this Wednesday (3) to discuss the risks and benefits of using these products and the regulation of the sector.

The meeting will be held at 2:30 PM in a plenary room to be determined.

Please consult the list of participants.

The debate is in response to a request from Representative Ana Pimentel (PT-MG). According to her, the objective is to promote a technical dialog on the growth of the dietary supplement market in the country, analyzing the impacts of unsupervised consumption and the benefits observed in uses supervised by healthcare professionals.

The parliamentarian points out that a study by the Brazilian Society of Endocrinology and Metabolism (SBEM) reveals that more than half of Brazilian households consume some type of supplement, often without adequate medical or nutritional supervision.

The Working Group on the Marketing of Dietary Supplements of the Chamber of Deputies will hold a public hearing to discuss the responsibility of digital platforms in the sale and advertising of counterfeit products.

This discussion is in response to a request from the group’s coordinator, Deputy Felipe Carreras (PSB-PE).

The congressman aims to address the role of digital platforms and marketplaces in monitoring and overseeing the sale of dietary supplements, particularly in light of the rise in sales of counterfeit products and those lacking health registration.

“Digital platforms have become the primary sales channels for dietary supplements in the country, but the lack of control over sellers and products has facilitated the spread of counterfeit and irregular items, endangering millions of consumers,” Carreras states.

“The hearing will provide an opportunity to discuss joint supervision mechanisms, platform accountability policies, and the need to enhance consumer protection legislation in the digital environment,” he adds.

The National Agency for Regulation, Control, and Health Surveillance (ARCSA in Spanish) has released a draft for a Partial Reform to Resolution ARCSA-DE-028-2016-YMIH – Technical Health Regulations for obtaining the Health Notification and Control of Food Supplements in establishments where they are manufactured, stored, distributed, imported, and marketed.

Representatives of the National Health Surveillance Agency (ANVISA in Portuguese) have warned about the poor quality of dietary supplements available in the national market. According to them, this sector leads the list of complaints regarding health violations and has a high number of disapproved products.

Representatives from both the agency and the supplement industry were interviewed by the Consumer Protection Commission of the Chamber of Deputies. For the companies, the solution lies in self-regulation and adherence to established legal standards.

The supplement sector receives the highest number of complaints regarding health violations, as stated by Renata de Araújo Ferreira, the inspection coordinator at ANVISA. Between 2020 and 2025, 63% of the investigations initiated by the agency involved these products. She emphasized that more than half of the complaints are related to misleading advertising of supplements sold on digital platforms, which complicates monitoring and oversight.

Renata Ferreira reported that ANVISA intends to employ artificial intelligence (AI) tools to expedite the identification of irregular products online. She confirmed that this technology has already been utilized, resulting in the removal of over 230,000 advertisements, approximately 60,000 of which were related to dietary supplements.

The Consumer Defense Commission of the Chamber of Deputies will discuss the quality and regulation of dietary supplements sold in Brazil. This discussion is in response to a request from Deputy Felipe Carreras (PSB-PE).

According to the congressman, the market for dietary supplements in Brazil has expanded in recent years, driven by the pursuit of health, wellness, and physical performance. He states that this increase in consumption has raised concerns regarding the quality and safety of these products.
