Agency Identifies Clandestine Product and False Advertising; Anvisa’s Determination Aims to Protect Consumers from Fraud and Health Risks.
The Anvisa (National Health Surveillance Agency) issued a critical alert to Brazilian consumers on Tuesday (16), strictly prohibiting the sale of two distinct products: Los Nobles olive oil and Zempyc Natural dietary supplement. The decision, published in the Official Gazette of the Union (DOU), mandates the immediate seizure of the items nationwide.
According to information from Agência Brasil, the Anvisa’s measure was taken due to serious risks to public health. The olive oil was classified as a product of clandestine origin, without any registration or sanitary control, while the supplement, which promised weight loss, has an unknown composition and utilized false advertising to attract customers online.
Los Nobles Olive Oil: The Risk of a Clandestine Product
The resolution from Anvisa is comprehensive and prohibits not only the sale but also the distribution, importation, advertising, and use of Los Nobles olive oil. The agency mandated the total seizure of the product, meaning it must be immediately removed from market shelves and any sales platforms.

The reason for the aggressive action, according to Agência Brasil, is the finding that the product is of clandestine origin. This means it has not undergone any type of sanitary control in Brazil and lacks the necessary authorization from Anvisa to be marketed.
Clandestine products pose a direct danger as there is no guarantee of their hygiene conditions, storage, or whether the contents of the bottle actually correspond to what is on the label.
Anvisa’s investigation also revealed a fraud that crosses borders. The product, which presented itself as Argentine, also lacks registration with the Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (Anmat), the agency equivalent to Anvisa in Argentina. The absence of registration in both countries reinforces the fraudulent nature of the operation and the complete lack of safety of Los Nobles olive oil.
Zempyc Natural: False Promise and Unknown Composition
In the same resolution, Anvisa targeted the supplement market that promises easy solutions for weight loss, prohibiting Zempyc Natural. This product was actively marketed on websites, e-commerce platforms, and mainly on social media, with strong claims of rapid weight loss.
The false advertising, as investigated by Anvisa, claimed benefits such as “fat burning,” “appetite reduction,” and “metabolism acceleration,” as well as increased energy and disposition. The agency’s main warning is that Zempyc Natural has totally unknown origin and composition, using an irregular designation. The lack of knowledge about the ingredients means consumers could be ingesting dangerous, prohibited substances or risky dosages without knowing.
To make matters worse, the Anvisa found that the label of Zempyc Natural used the name of an established pharmaceutical company to generate false credibility. However, when contacted by the agency, the pharmaceutical company itself denied any involvement. The company “stated that it did not locate in its internal controls any product with the designation Zempyc,” as reported by Agência Brasil, characterizing the supplement as a complete fraud.
