Unapproved Substances Found in Weight Loss and Workout Supplements
An international body of health groups has identified four unapproved, potentially dangerous stimulants in six over-the-counter weight-loss and pre-workout products available in the United States. The research was conducted by the global public health organization NSF International, Harvard Medical School, the United States Department of Defense, and the National Institute for Public Health and the Environment in the Netherlands (RIVM). The substances they identified were not listed as ingredients on the product labels and may be similar to a compound derived from ephedra, which was banned by the FDA in 2004 due to serious side effects and related deaths.
The compounds, which include banned stimulants 1,3-DMAA and 1,3-DMBA, octodrine, and a newly-identified DMAA analog, can cause heart attack, hemorrhagic stroke, or sudden death, especially when taken before strenuous exercise or combined with caffeine. Manufacturers of these products may disguise the stimulants as “2-aminoisoheptane” or Aconitum kusnezoffii on product labels. Consumers are urged to avoid using products containing these substances.
According to the researchers, weight-loss and pre-workout products containing these banned or unapproved stimulants include Game Day, Infrared, 2-aminoisopheptane, Simply Skinny Pollen, Cannibal Ferox AMPED, and Triple X. Results of the study were published in Clinical Toxicology.
