07 Sep 2018 --- New peer-reviewed research into weight-loss and sports/energy supplements containing higenamine has found unpredictable, inaccurately labeled and potentially harmful dosages of the stimulant. Based on the findings, the researchers are urging consumers to use caution when consuming supplements labeled as containing higenamine. The use of dietary supplement leads to an estimated 23,000 emergency department visits each year in the US, and weight loss and sports supplements contribute to a large portion of these emergency department visits. The cardiovascular stimulant higenamine was added by the World Anti-Doping Agency (WADA) to the list of substances prohibited in sport two years ago.
