Maker of Mexican dietary supplement used fake addresses and lied about ingredients

A USA Today investigation found that consumers who buy Reumofan, a Mexican dietary supplement considered a "100% natural" treatment for arthritis and joint pain, "are risking dangerous side effects and trusting their lives to a company that uses fake addresses, lies about the ingredients in its products and may not even exist."

USA Today set out to find the company behind Reumofan products, Riger Natural, and the people responsible through searching corporation records and visiting addresses listed for it in Mexico. The addresses were fake, and no evidence exists the companies ever had facilities in the locations, USA Today reports: "Even Mexican health authorities have been unable to track down the company."
