Higenamine -- A Potentially Dangerous Stimulant -- Found in Some Supplements
A recent study found concerningly high doses of the stimulant higenamine in some weight loss, energy and sports supplements sold in the U.S. Higenamine is a naturally-occurring stimulant which is permitted to be sold as a dietary supplement ingredient in the U.S. However, the substance is known to increase heart rate and have other serious cardiovascular effects when small doses (less than 5 mg) are taken intravenously, and there are no known studies on the effects of taking the large, oral doses found in many of the supplements that were tested.
