The FDA has recalled too many male sexual-health supplements to mention, but loads of them have been removed from the market for containing tadalafil or sildenafil (or their analogs), the active ingredients in Cialis and Viagra, respectively. Those prescription drugs treat erectile dysfunction by opening up blood vessels, but they can react with nitrates and cause blood vessels to become overly dilated, causing a potentially fatal drop in blood pressure. Banned products include True Man Sexual Energy, Friminite, Love Rider, Jack Rabbit, SexVoltz, Virilis Pro, Silver Sword, Lightning Rod, Rock-It Man, and a host of other tastefully and subtly named supplements. These products are so numerous that the FDA can't keep up with them all, and it has simply offered a blanket warning against using any sexual-performance supplements.
