Dental health is nothing to floss over.
Maybe it's a coincidence that sales of Metabolife 356 and other ephedra diet aids skyrocketed after the FDA yanked fen-phen from the market. That recall came after the agency received about 100 reports of heart-valve damage linked to the prescription drug. It makes you wonder what the agency is waiting for with ephedra. By 1996, David Kessler, FDA commissioner at the time, was growing alarmed about ephedra. The FDA issued a consumer alert, warning people to avoid ephedrine-based stimulants.
