Incident Report: Detection of Phenibut in Nutritional Supplements

Date: August 14, 2025

In a recent food safety incident reported through the Rapid Alert System for Food and Feed portal, it has been confirmed that phenibut, a substance not typically approved for use in dietary products, has been detected in certain nutritional supplements originating from the United Kingdom. This finding raises significant concerns regarding the safety and compliance of these products within the food supply chain.

Background: Phenibut is a central nervous system depressant that is often used for its anxiolytic properties. However, its presence in nutritional supplements poses potential health risks to consumers, particularly if they are unaware of its inclusion in the product formulation. The detection of such a substance highlights the importance of stringent quality control measures in the production of dietary supplements.

Health Implications: The consumption of products containing phenibut can lead to various side effects, including sedation, dizziness, and potential dependency issues. Consumers are advised to exercise caution and consult healthcare professionals if they have ingested any supplements that may contain this substance.

Recommendations: It is crucial for regulatory authorities to investigate the source of this contamination and take appropriate measures to ensure that affected products are removed from the market. Consumers should remain vigilant and report any adverse effects experienced after using nutritional supplements.

Continued monitoring and regulation are essential to maintain food safety and protect public health.
