In high-income countries, shopping for non-prescription multivitamin-multimineral supplements has tremendously increased. The purpose of this labeling analysis is to inform on the daily elemental iron (with or without vitamin C) supply provided by multivitamin-multimineral supplements sold online by Amazon in Western and Southern Europe (amazon.es, amazon.de, amazon.it, and amazon.fr). We identified 298 iron-containing multivitamin-multimineral preparations sold by Amazon marketplaces: 153 preparations sourced from amazon.de, 68 from amazon.fr, 54 from amazon.it, and 23 from amazon.es. The daily iron dose provided by these preparations was 14 [5-14] mg (median and interquartile range), with no differences among the marketplaces. Approximately 90% (n = 265) of the preparations contained ferrous iron. Moreover, 85% (n = 253) of the preparations were fortified with vitamin C in a dose of 80 [40-100] mg daily. Conclusions. The median supply of iron (about 14 mg) and vitamin C (80 mg) in iron-containing multivitamin-multimineral preparations offered on Amazon platforms in Western and Southern Europe falls below that currently recommended for iron deficiency in review articles, namely 100 mg of iron and 500 mg of vitamin C per day. The iron supply of iron-containing multivitamin-multimineral preparations falls also below the dose of 30-60 mg advocated to prevent iron deficiency in menstruating women.
在高收入国家，购买非处方多种维生素-矿物质补充剂的行为大幅增加。本标签分析旨在说明在西欧和南欧（amazon.es、amazon.de、amazon.it 和 amazon.fr）的亚马逊在线市场上销售的多种维生素-矿物质补充剂中，每日元素铁（含或不含维生素 C）的供应量。我们共鉴定了 298 种含铁的多种维生素-矿物质补充剂，这些补充剂均由亚马逊市场供应：153 种来自 amazon.de，68 种来自 amazon.fr，54 种来自 amazon.it，23 种来自 amazon.es。这些制剂提供的每日铁剂量为 14 [5-14]mg（中位数和四分位间距），各市场间无差异。大约 90%（n = 265）的制剂含有硫酸亚铁。此外，85%（n = 253）的制剂中添加了维生素 C，剂量为 80 [40-100]mg/天。结论：在西欧和南欧的亚马逊平台上提供的含多种维生素-矿物质制剂中，铁（约 14mg）和维生素 C（80mg）的中位供应量低于目前综述文章中推荐的缺铁治疗剂量，即每天 100mg 铁和 500mg 维生素 C。含多种维生素-矿物质制剂中的铁供应量也低于主张用于预防经期妇女缺铁的 30-60mg 剂量。
