市售「葡萄糖胺」產品之葡萄糖胺含量
Glucosamine Content in Commercially Available Glucosamine Nutritional Supplements
摘要
在臺灣，患有關節炎的人數逐漸增加。由於葡萄糖胺被認為可促進軟骨的形成和修復，市場上有許多品牌的葡萄糖胺（鹽酸鹽）營養補充品，其中大多數皆標榜含有葡萄糖胺（鹽酸鹽）。由於臺灣衛生福利部（MOHW）從未公告要求在標籤上標明葡萄糖胺的含量，因此各產品間可能會有很大差異。本研究中，吾等隨機購買12種市售的“葡萄糖胺（鹽酸鹽）營養補充品”，並參照衛生福利部建議的檢驗方法對其含量進行檢測。宣稱的葡萄糖胺濃度的準確性係根據“健康食品安定性測試指引”所建議的±20%加以確認。本研究亦將每個產品的葡萄糖胺濃度轉換為膳食參考攝入量（Dietary Reference Intakes, DRI）。結果顯示，8件（66.6%，8/12）含有葡萄糖胺的產品和4件（33.3%，4/12）含有葡萄糖胺鹽酸鹽的產品沒有達到推薦的1,500 mg DRI，其中，甚至有一種產品不含葡萄糖胺。基於這些結果，吾等敦促衛生主管部門對這類產品應制定葡萄糖胺（鹽酸鹽）的標準含量。吾等亦建議對市場上的產品進行定期監測，以確保此產品的葡萄糖胺含量達到DRI的要求，維護消費者的權益。

The number of individuals suffering from arthritis is increasing in Taiwan. Because glucosamine has been shown to promote cartilage formation and repair, many brands of glucosamine nutritional supplements are on the market, most of them contain glucosamine hydrochloride. As the Ministry of Health and Welfare, Taiwan (MOHW) has never issued the requirement to indicate glucosamine content on the label, it may vary greatly. In this study, 12 commercially available ＂glucosamine nutritional supplements＂ were randomly purchased and tested for glucosamine content with the method recommended by MOHW. The accuracy of the claimed glucosamine concentration was determined according to the ＂Health Food Stability Test Guidelines,＂ and the glucosamine concentration of each product was converted to Dietary Reference Intakes (DRI). Results showed that 8 (66.6%, 8/12) products containing glucosamine and 4 (33.3%, 4/12) products containing glucosamine hydrochloride did not meet the recommended DRI of 1,500 mg and that one product did not even contain glucosamine. Based on these results, we urge the health authorities to establish the standard glucosamine content for these products. We also recommend regular monitoring of commercially available products to ensure that the DRI requirement is met and that the rights of consumers are guaranteed.
