ZUBB Dietary Supplement may be harmful due to hidden ingredient

[9/4/2026] The Food and Drug Administration is advising consumers not to purchase or use ZUBB Dietary Supplement, a product promoted and sold for weight loss on various websites and possibly in some retail stores. This product was identified during an examination of international mail shipments.

FDA laboratory analysis confirmed that ZUBB Dietary Supplement contains sildenafil not listed on the product label.

ZUBB Dietary Supplement Packaging

Sildenafil is the active ingredient in the FDA-approved prescription drug Viagra, used to treat erectile dysfunction. It may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels. This is especially concerning for people with diabetes, high blood pressure, high cholesterol or heart disease who commonly take nitrate-containing medications.

 

Health care professionals and consumers should report adverse events or side effects related to the use of this product to FDA's MedWatch Safety Information and Adverse Event Reporting Program:  

This notification is to inform the public of products potentially marketed as dietary supplements or conventional foods with hidden ingredients. These products are typically promoted for sexual enhancement, weight loss, pain relief and body building and are often represented as being all natural. Consumers should exercise caution before purchasing these products. 

 

FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients.
