Dietary Supplement Ingredient Database (DSID) release 4.0

The Dietary Supplement Ingredient Database (DSID) provides estimated levels of ingredients in dietary supplement products sold in the United States. These statistically predicted estimates may differ from labeled amounts and are based on chemical analysis of nationally representative products. The DSID was developed by the Nutrient Data Laboratory, US Department of Agriculture, in collaboration with the Office of Dietary Supplements at the National Institutes of Health (NIH) and other federal agencies. DSID-4 reports national estimates of ingredient content in adult, children’s and non-prescription prenatal multivitamin/mineral (MVMs) and omega-3 fatty acid supplements.

New! Analytically-validated mean estimates for vitamin D, vitamin A and chromium in adult MVMs are reported for the first time, and estimates for 18 other ingredients have been calculated based on a new, second study of representative adult MVMs. DSID-4 also reports results for the first DSID study of botanical dietary supplements. The “Green Tea Research Summary and Results" are available on the 'Botanicals' page.

The DSID is intended primarily for research applications. These data are appropriate for use in population studies of nutrient intake rather than for assessing content of individual products.

膳食补充剂成分数据库（Dietary Supplement Ingredient Database, DSID）可为美国境内在售的膳食补充剂产品提供成分含量预估数值。此类经统计学推导得出的预估结果可能与产品标签标注量存在差异，其基于对具有全国代表性的产品所开展的化学分析。该数据库由美国农业部营养数据实验室联合美国国立卫生研究院（National Institutes of Health, NIH）膳食补充剂办公室及其他联邦机构共同开发。
DSID-4 报告了成人、儿童及非处方产前复合维生素/矿物质（multivitamin/mineral, MVM）补充剂与ω-3脂肪酸补充剂的成分含量全国预估数据。
新增内容：本版本首次公布了针对成人复合维生素/矿物质补充剂中维生素D、维生素A及铬的经分析验证的均值预估结果；同时基于一项针对代表性成人复合维生素/矿物质补充剂的全新第二轮研究，计算得到了其余18种成分的预估数据。DSID-4 同时公布了首项针对植物源性膳食补充剂的DSID研究成果。“绿茶研究综述与结果”可在“植物源成分”页面查阅。
该数据库主要面向科研应用场景。此类数据适用于人群营养摄入水平研究，而非用于单款产品的成分含量评估。
