Abstract

The goal of this study is to establish the presence or absence of anabolic androgenic steroids in food supplements implemented in sports practice, to assess the health risk from intake of food supplements with quality and content discrepancies in conflict with the recommendations. The authors analysed 23 samples of food supplements by using liquid chromatographic methods. The presence/absence of substances with steroid structure was determined by considering the resulting chromatograms and using reference substances. The analysis of the resulting data showed that 11 out of 23 samples of food supplements did not contain anabolic steroid substances, while different amounts of androgenic steroid substances were identified in the other 12 samples. The results from the analyses confirmed the hypothesis formulated by the authors for possible presence of undeclared steroid ingredients in food supplements, and enabled the following conclusion: more than half of the tested food supplements contained undeclared anabolic steroids, all banned by the World Anti-Doping Agency, and their number in one of the samples could be more than one. The authors also revealed that the information on the product label and package concealed the undeclared ingredients of the food supplement and claimed for high efficacy and safety.
体育运动中膳食补充剂中合成代谢类固醇含量的调查
本研究的目的是确定在运动中使用的食品补充剂中是否含有合成代谢雄激素类固醇,以评估摄入质量和含量与建议不符的食品补充剂对健康的风险。采用液相色谱法对23份食品添加剂样品进行了分析。通过考虑得到的色谱图和参考物质来确定类固醇结构物质的存在/不存在。对结果数据的分析显示,在23份食品补充剂样品中,有11份不含合成代谢类固醇物质,而在另外12份样品中发现了不同数量的雄激素类固醇物质。分析结果证实了作者提出的假设,即食品补充剂中可能存在未申报的类固醇成分,并得出以下结论:超过一半的测试食品补充剂含有未申报的合成代谢类固醇,这些类固醇都被世界反兴奋剂机构禁止使用,其中一个样本中的类固醇含量可能不止一种。作者还透露,产品标签和包装上的信息掩盖了未申报的食品补充剂成分,并声称其高效安全。
