A dietary supplement that had been marketed online is now under recall after the U.S. Food and Drug Administration (FDA) discovered that it contained undeclared erectile dysfunction medications.
FDA Announcement and Company Response
The FDA released a notice this week detailing the findings from its testing of the MR.7 SUPER 700000 capsules. StuffbyNainax LLC, the manufacturer, immediately announced that it was recalling all lots of the product. The company’s statement explained that the supplement was found to contain Sildenafil and Tadalafil, the active ingredients in male erectile dysfunction treatments.
Because these drugs are prescription-only medications, the FDA stated that products containing them cannot be marketed as dietary supplements. The company warned that consuming the undeclared drugs could pose “serious health risks.”
Health Risks and Drug Interactions
The recall notice highlighted a specific danger: the potential interaction between the erectile dysfunction drugs and nitrates that are used in certain prescription medications. The statement read, “These ingredients may interact with nitrates found in certain prescription medications (such as nitroglycerin) and may result in a dangerous drop in blood pressure, which can be life-threatening.”
The notice also identified groups of consumers who are at higher risk. It said, “Individuals with diabetes, high blood pressure, high cholesterol, or heart disease frequently take nitrates. Adult males who use nitrates for cardiac conditions are at the greatest risk.”
Distribution and Product Details
The affected supplement was primarily sold online and was distributed nationwide to a limited number of consumers between August 2025 and November 2025. The product lacked lot numbers and expiration dates, making it difficult for consumers to identify specific batches.
StuffbyNainax LLC’s recall covers all available lots of MR.7 SUPER 700000 capsules. The company is working with the FDA to ensure that consumers who purchased the product are notified and can return the capsules for a full refund.
What Consumers Should Do
If you purchased MR.7 SUPER 700000 capsules during the period of distribution, you should check the packaging for any identifying marks. Because the product did not include lot numbers, you should contact StuffbyNainax LLC directly or consult the FDA’s recall website for instructions on how to return the product.
Consumers who have taken erectile dysfunction medications or who are on nitrate therapy should seek medical advice if they have consumed the recalled supplement. The potential for a severe drop in blood pressure warrants immediate medical attention.
Industry Implications
This recall underscores the importance of regulatory oversight for dietary supplements. The FDA’s role in identifying undeclared prescription drugs in over-the-counter products remains critical to consumer safety. The incident also highlights the challenges faced by online supplement distributors, where product labeling can sometimes be incomplete or inaccurate.
Key Takeaways
