Nowadays, food supplements are widely consumed, often without any medical supervision. In this study, 25 food supplements for weight loss, randomly purchased from five different suppliers in the European Union, were analysed by Wavelength Dispersive X ray Fluorescence spectrometry (WDXRF). The aim of this study was the risk assessment of trace elements and the mixture of elements present in food supplements for weight loss. The obtained Hazard Index (0.11) showed no potential risk of non-carcinogenic effects to human health. However, since humans are frequently exposed by different routes and/or sources to toxic metals, the additional consumption of these products may cause potential toxicological risks that cannot be ignored. In one analysed food supplement (FS), the simultaneous presence of Pb and Mn in high concentrations was detected. In two, FS chromium concentrations were above the reference daily dose. Unconformities were detected between the labelled and the detected values, which emphasises the misinformation of labels. This highlights the need for a deeper surveillance of food supplements.
如今，食品补充剂被广泛食用，往往没有任何医疗监督。在这项研究中，我们使用波长色散 X 射线荧光光谱法（WDXRF）对从欧盟五个不同供应商随机购买的 25 种减肥食品补充剂进行了分析。本研究的目的是评估微量元素和减肥食品补充剂中元素混合物的风险。获得的危害指数（0.11）表明，这些产品不会对人类健康造成非致癌影响的潜在风险。然而，由于人类经常通过不同的途径和/或来源接触有毒金属，因此额外摄入这些产品可能会带来不可忽视的潜在毒理学风险。在一个被分析的食品补充剂（FS）中，同时检测到 Pb 和 Mn 的高浓度存在。在两种 FS 中，铬的浓度高于参考日剂量。标签和检测值之间存在差异，这突出了标签信息的不准确。这强调了需要更深入地监测食品补充剂。
