The Brooklyn, New York-based company Junp LLC is voluntarily recalling a particular lot of its MegMan Performance Booster capsules, according to a notice published by the U.S. Food & Drug Administration (FDA). The affected lot number is 2010291, and the product has an expiration date of Jan. 7, 2024. The capsules are packaged in blister packs of 10 within a carton with the UPC number 8 48998 0091 2. RELATED: This Is the One Vitamin You Should Never Take, Doctors Say. The reason for the recall is that the capsules may contain Tadalafil. This is an ingredient used in products that are approved by the FDA for the treatment of male erectile dysfunction in the family of drugs known as phosphodiesterase (PDE-5) inhibitors. However, the MegMan Performance Booster capsules are not approved by the FDA, and therefore the presence of the ingredient puts the supplement in the class of unapproved drugs, “for which the safety and efficacy has not been established,” according to the recall notice. This makes them subject to recall. RELATED: This Is the One Vitamin You Should Never Take, Doctors Say. The undeclared tadalafil may present “serious health risks” to users of this supplement with underlying health issues. For example, PDE-5 inhibitors may interact with nitrates found in some prescription drugs (such as nitroglycerin), and this interaction can result in lowering blood pressure to “dangerous levels that may be life-threatening,” according to the recall notice. People who have diabetes, high blood pressure, or heart disease often take drugs that contain nitrates. Fortunately, Junp LLC has not received any reports of health problems related to the recalled supplements so far.
