Dietary supplements are popular worldwide and their use has been increasing. The purpose of this study was to evaluate the mineral contents of multi-vitamins and minerals (MVMs) in most commonly sold among dietary supplements. Ninety popular MVM supplements sold in South Korea were surveyed regarding their characteristics and ingredients including minerals listed on the labels through off-line and on-line search. Daily mineral contents of the MVM supplements were compared with Korean Dietary Reference Intakes (DRIs) by target populations. The average price of 90 MVM supplements was $41.3 per bottle, with a price of $0.9 per day and the average number of minerals contained per supplement was 4.7. A total 14 minerals were found in the MVM supplements including calcium, phosphorus, sodium, potassium, and magnesium. Nine minerals (e.g. calcium, magnesium, and iron) were included in more than 30% of the MVM supplements examined. When daily mineral dose of MVMs was compared to DRIs, calcium was the lowest (34.0% of recommended intake [RI]) and chromium was the highest (218.7% of adequate intake [AI]), and zinc, copper, selenium, and chromium were also higher than their RI or AI levels. The daily mineral contents of the 90 MVM supplements were below the tolerable upper-intake level, but some minerals were higher than RI or AI with high variance among products. Therefore, there is a great need to educate the public for the adequate selection and use of MVM supplements based on the contents of MVM supplements and individual's mineral intake derived from the diet.
膳食补充剂在全球都很受欢迎,其使用量一直在增加。本研究的目的是评估膳食补充剂中最常销售的多种维生素和矿物质(MVM)产品的矿物质含量。通过线下和线上搜索,对韩国销售的90种流行的MVM补充剂的特征和成分(包括标签上列出的矿物质)进行了调查。将MVM补充剂的每日矿物质含量与韩国不同目标人群的膳食参考摄入量(DRIs)进行了比较。90种MVM补充剂的平均价格为每瓶41.3美元,每天0.9美元,每种补充剂所含矿物质的平均数量为4.7种。在MVM补充剂中总共发现了14种矿物质,包括钙、磷、钠、钾和镁。超过30%的被检测MVM补充剂中含有9种矿物质(如钙、镁和铁)。当将MVM的每日矿物质剂量与DRIs进行比较时,钙含量最低(为推荐摄入量[RI]的34.0%),铬含量最高(为适宜摄入量[AI]的218.7%),锌、铜、硒和铬也高于其RI或AI水平。90种MVM补充剂的每日矿物质含量低于可耐受的最高摄入量水平,但一些矿物质高于RI或AI,且产品间差异很大。因此,非常有必要根据MVM补充剂的成分以及个体从饮食中摄入的矿物质情况,对公众进行关于MVM补充剂的正确选择和使用的教育。
