![]() ![]() While poorly studied, reported side effects include hypertension, dyspnea and hyperthermia. Octodrine is a discontinued nasal decongestant first developed in the 1940s. Supplements containing deterenol have been linked to adverse events such as nausea, vomiting, sweating, agitation, palpitations, chest pain, and cardiac arrest. Deterenol is banned in most countries and not approved for use in humans in the US. Six products contained one of these prohibited ingredients, and one contained a combination of four prohibited ingredients.ġ,4 Dimethylhexylamine, or 1,4-DMAA, is an analog of 1,3-DMAA which, according to the FDA, is an amphetamine derivative that can raise blood pressure and lead to cardiovascular problems including shortness of breath, chest tightening and heart attack.ĭeterenol is a synthetic stimulant, also known as Betaphrine. Five different FDA-prohibited compounds were found, including four synthetic simulants, 1,4-dimethylamylamine (DMAA), deterenol, octodrine (DMHA), oxilofrine and omberacetam. Seven of the products (12%) were found to contain at least one FDA-prohibited ingredient. Only six products (11%) contained an ingredient quantity within 10% of the label. ![]() Of the 34 products that contained detectable amounts of the listed ingredient, the actual quantity ranged from 0.02% to 334% of the labeled quantity. Twenty-three of the products (40%) did not contain a detectable amount of the labeled ingredient. In the paper, "Presence and Quantity of Botanical Ingredients With Purported Performance-Enhancing Properties in Sports Supplements," published in JAMA Network Open, the researchers detail their findings of erroneous labeling and dangerous ingredients.įifty-seven products were analyzed containing one of five popular supplements, R vomitoria (n=13), methylliberine (n=21), turkesterone (n=8), halostachine (n=7) and octopamine (n=8). Scientists at Cambridge Health Alliance, Massachusetts Harvard Medical School, Massachusetts University of Mississippi and NSF International, Michigan, have analyzed the ingredients in a selection of sports supplements purchased online with liquid chromatography–quadrupole time-of-flight mass spectrometry and discovered 89% to be inaccurately labeled, and 12% included unlabeled banned drug substances. ![]()
