Abstrakt:	Food supplements are a category of products perceived safe and therefore commonly used by different categories of consumers without any particular attention or precaution. However, health risks associated with the consumption of supplements containing undeclared substances cannot be excluded. A variety of analytical methods are used to control supplement quality composition, but usually, these procedures are complex and time-consuming. Here, we report the results of a simple and fast liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, to detect and quantify simultaneously different categories of active molecules, such as biogenic ammines and natural alkaloids that at high doses can produce negative health effect in consumers. Three categories of products intended for body weight loss, energy boosting, and erectile dysfunction treatment, purchased through e-commerce sites and from local supermarkets, were analyzed (n = 91). The caffeine, synephrine, agmatine sulfate, yohimbine, phenethylamine, and icariin were correctly separated and identified with good precision (RSD < 20%) and recovery (89-109%). The identification and quantification of the analytes in real samples highlighted that the 26% of the samples were not compliant with labeling, confirming that frauds are very common also in the natural supplements market. This LC-MS/MS method could be easily used to test natural supplements in order to check the correct labeling and to protect consumers from potential health risks and food frauds.
