摘要

咖啡因是一种很容易在日常营养和运动补充剂中摄入的物质。超过每日推荐的咖啡因剂量可能会导致严重的健康问题。研究表明,人们对运动补充剂标签与其内容之间的不相容性提出了许多担忧。本研究旨在调查首次从土耳其市场购买的运动补充剂中的咖啡因含量,并评估产品的标签信息。对41种运动补充剂中的咖啡因浓度进行了测定,并考虑到计算的每日消耗剂量,强调了可能的不良影响。41种产品中有17种样品被发现含有咖啡因,含量从4.52到471毫克/毫升不等。三种含有咖啡因的产品未申报其咖啡因成分。尽管有三种产品没有具体说明咖啡因的含量,但发现其含量超过了每日推荐的咖啡因限量(400毫克/天)。标签上显示的数量与7种产品中确定的咖啡因数量之间存在显著差异(p<0.05)。17种咖啡因标签产品中有8种比标签信息高151-948%。总体而言,29.4%的含咖啡因产品(n=17)超过了建议摄入量。摄入超过每日推荐剂量可能会导致严重的不良反应,消费者可能会面临严重的健康风险,如动脉高压、冠心病,以及睡眠问题、易怒、焦虑、头痛和烦躁不安。考虑到这些健康风险,消费者的意识和运动补充剂上准确的产品标签对于防止人们遭受不良后果变得更加重要。

Investigation of caffeine concentrations in sport supplements and inconsistencies in product labelling
Caffeine is a substance that can be easily consumed in daily nutrition as well as in sport supplements. Exceeding the daily-recommended dose for caffeine may cause serious health problems. Studies illustrated that many concerns have been raising about the incompatibility between labels on sport supplements and their contents. The present study aimed to investigate caffeine contents in sport supplements purchased from Turkey market for the first time and to evaluate label information on products. Caffeine concentrations were determined in 41 sport supplements and possible adverse effects were emphasized considering calculated daily consumption doses. Seventeen samples among 41 products were found to be caffeine containing, ranging from 4.52 to 471 mg/mL. Three of caffeine containing products were undeclared their caffeine ingredients. Although three products were not specified caffeine their amounts, findings were found above the daily-recommended caffeine limit (400 mg/day). Significant differences were observed between the quantities indicated on the labels and the determined caffeine amounts in 7 products (p<0.05). Eight of 17 caffeine labelled products were found between 151-948% higher than stated label information. Overall, 29.4% of caffeine containing products (n=17) were found over the recommended intake. Consuming more than the daily-recommended dose may cause severe adverse reactions and consumers may experience serious health risks such as arterial hypertension, coronary heart disease, as well as sleep problems, irritability, anxiety, headache, and restlessness. Considering these health risks, awareness of consumers and accurate product labels on sport supplements gain more importance to prevent people from undesired consequences.
