The U.S. Food and Drug Administration (FDA) has injectable vitamin C on its radar, according to a recent Action Alert from the Alliance for Natural Health-USA (ANH), an organization that works to protect consumer access to natural health products. ANH’s announcement that the FDA recently informed a pharmacy that it could no longer manufacture or distribute injectable vitamin C is creating reaction and protest on the Internet.

Intravenous vitamin C, often combined with other vitamins, is used by many naturopaths and other integrative health practitioners to treat conditions such as chronic fatigue syndrome, mononucleosis and the flu.

According to the group’s Action Alert, the FDA’s recent action is “is wiping out one of the best potential treatments for these conditions.”

“There are so many dangerous drugs out there that the FDA should be focusing on [instead of injectable vitamin C],” says ANH Executive Director Gretchen DuBeau. In its Alert, DuBeau’s group calls for readers to contact the FDA to “stop the war” on intravenous vitamin C.
