In November 2001, the Food and Drug Administration (FDA) issued a consumer and health professional warning about the product. They told the supplement's distributor to take "prompt action" to remove LipoKinetix® from the market.
The distributor does not currently list the product on its Internet site.
The ingredients in LipoKinetix® appear in other supplements marketed by the manufacturer, and in other products sold on bodybuilding and nutritional supplement Internet sites.
An accompanying editorial points out the need for regulation of dietary supplements, assurances of product safety, and ongoing monitoring and enforcement of safety standards.
