WASHINGTON, D.C. (November 3, 2025) — The U.S. Food and Drug Administration (FDA) has issued an urgent safety warning stating that certain weight loss and sexual enhancement supplements may contain Yellow Oleander, a highly toxic plant extract associated with severe cardiac poisoning. According to the FDA, the affected products are being marketed online and in retail stores under various names and are falsely represented as natural or plant-based remedies.
The agency confirmed that laboratory analysis of multiple samples revealed the presence of Thevetia peruviana, commonly known as Yellow Oleander, a toxic substance that can cause severe poisoning or death even in small amounts. Consumers are urged to stop using the supplements immediately.

What Happened?
According to the FDA, samples of the supplements underwent laboratory testing after officials received complaints of individuals experiencing dizziness, vomiting and abnormal heartbeat. The agency stated that the supplements were marketed as herbal alternatives but were instead laced with Yellow Oleander extract, a toxic plant commonly found in Central and South America.
The FDA said it became aware of the issue after consumers reported adverse reactions to products purchased from online retailers and social media advertisements. The recall was announced on November 3, 2025, as the agency works to identify all affected brands and distribution channels.
Affected Products
Brand | Product type | Form | Risk | Distribution |
Various online sellers (names undisclosed) | Weight loss supplements | Capsules | Toxic Yellow Oleander | U.S. nationwide |
Various online sellers (names undisclosed) | Sexual performance supplements | Capsules | Toxic Yellow Oleander | U.S. nationwide |
Note: Specific brand names, UPC codes, and lot numbers have not been disclosed by the FDA as the investigation is ongoing. Consumers should exercise caution with any weight loss or sexual enhancement supplements purchased from unverified online sources.
What Caused the Issue?
Yellow Oleander contains cardiac glycosides, which are compounds that directly affect heart function. According to the FDA notice, ingesting it can lead to life-threatening heart rhythm abnormalities.
The agency confirmed symptoms may include:
- Nausea and vomiting
- Irregular heartbeat
- Dizziness
- Confusion
- Cardiac arrest
No deaths have been reported yet, but consumers have been hospitalized.
Those most at risk include:
- Pregnant individuals
- Children
- Older adults
- People with existing heart conditions
The FDA stated that the substitution appears to be intentional, with distributors replacing legitimate ingredients with the toxic plant extract to reduce costs while falsely marketing products as natural herbal remedies.

Behind the Brand
The products appear to be internationally sourced and resold through various online platforms and social media marketplaces. According to the FDA, many of the supplements are manufactured overseas and then distributed through third-party sellers who market them using misleading natural health claims.
Source86 attempted to identify and contact the distributors involved, but specific brand information remains undisclosed as the FDA investigation continues. The agency has indicated it is working with international regulatory partners and e-commerce platforms to remove dangerous products from circulation.
Other Relevant Recalls
In December 2024, VidaSlim issued a recall of its popular weight-loss dietary supplements after independent testing found Yellow Oleander contamination. The U.S. Food and Drug Administration (FDA) alerted consumers that the products contained undeclared toxic plant extract capable of causing serious cardiac effects, underscoring how dangerous misbranded supplements continue to pose risks in the direct-to-consumer market.

Ensuring Safe Eats
This warning signals a growing problem: unregulated supplement imports promoted through social media and e-commerce platforms. The incident demonstrates how digital distribution channels can circumvent traditional safety oversight, putting consumers at serious risk.
Food and supplement companies must prioritize rigorous supplier vetting, comprehensive testing protocols, and transparent supply chain documentation. Consumers should purchase supplements only from reputable sources with clear manufacturing information and third-party testing certifications.
If you have purchased any weight loss or sexual enhancement supplements from online sellers, particularly those marketed as natural or herbal alternatives, exercise extreme caution and consider discontinuing use until more information becomes available from the FDA.
