The use of dietary supplements is a popular form of health behavior, especially among women. Little research has been conducted to determine consumers' comprehension of supplement label information. Therefore, this research evaluated comprehension of supplement label information among women 25-45 years of age who consumed a dietary supplement > or =4 times per week. Participants (n=51) completed a written questionnaire about supplement practices, a 10-item knowledge test, and an individual interview about terms used on supplement labels. Participants answered 70% of the questions correctly on the knowledge test indicating adequate knowledge of dietary sources of nutrients. Knowledge of recommended dosages, dosing instructions, and instructions about inappropriate use of supplements for certain people also was adequate. However, misconceptions regarding the term "natural" on supplement labels, product claims, and testing for product safety existed among participants. Supplement users need additional education about supplement claims and testing for product safety and efficacy to make informed health care choices.
使用膳食补充剂是一种流行的健康行为方式，在女性中尤为普遍。针对消费者对补充剂标签信息的理解所开展的研究很少。因此，本研究评估了每周服用膳食补充剂≥4次的25至45岁女性对补充剂标签信息的理解情况。参与者（n = 51）完成了一份关于补充剂使用习惯的书面问卷、一项包含10个问题的知识测试，以及一次关于补充剂标签上所用术语的个人访谈。参与者在知识测试中正确回答了70%的问题，表明她们对营养素的膳食来源有足够的了解。对推荐剂量、给药说明以及关于某些人群不适合使用补充剂的说明的了解也足够。然而，参与者中存在对补充剂标签上“天然”一词、产品宣称以及产品安全性检测的误解。补充剂使用者需要接受关于补充剂宣称以及产品安全性和功效检测方面的更多教育，以便做出明智的医疗保健选择。
