超过一半的美国成年人使用膳食补充剂。一些报告表明，补充剂使用者从食物中摄入的维生素比非使用者高，但这一观察结果尚未使用全国代表性的调查数据进行检验。本分析的目的是使用2003-2006年国家健康和营养调查成人（年龄≥19岁）的数据（n= 8，860），通过补充剂使用检查食物中的维生素摄入量，以及膳食补充剂如何有助于达到或超过选定维生素的膳食参考摄入量。在男性使用者中，叶酸和维生素A，E和K的平均摄入量显着高于非使用者。在女性中，服用者的叶酸和维生素A、C、D和E的平均摄入量高于非服用者。总摄入量（食物和补充剂）高于我们检查的每种维生素的使用者比非使用者的膳食维生素摄入量。补充剂的使用有助于降低我们检查的每种维生素的摄入量低于估计平均需要量的患病率，但对于叶酸和维生素A，B-6和C，补充剂的使用增加了摄入量高于可耐受上限的可能性。补充剂的使用与使用者中某些维生素的平均摄入量高于非使用者相关，但与摄入量低于估计平均需要量的患病率无关。那些不使用维生素补充剂的人维生素摄入不足的患病率显着较高;然而，使用补充剂可能会导致某些维生素的过量摄入。
More than half of US adults use dietary supplements. Some reports suggest that supplement users have higher vitamin intakes from foods than nonusers, but this observation has not been examined using nationally representative survey data. The purpose of this analysis was to examine vitamin intakes from foods by supplement use and how dietary supplements contribute to meeting or exceeding the Dietary Reference Intakes for selected vitamins using data from the National Health and Nutrition Examination Survey among adults (aged ≥19 years) in 2003–2006 (n=8,860). Among male users, mean intakes of folate and vitamins A, E, and K from food sources were significantly higher than among nonusers. Among women, mean intakes of folate and vitamins A, C, D, and E from foods were higher among users than nonusers. Total intakes (food and supplements) were higher for every vitamin we examined among users than the dietary vitamin intakes of nonusers. Supplement use helped lower the prevalence of intakes below the Estimated Average Requirement for every vitamin we examined, but for folic acid and vitamins A, B-6, and C, supplement use increased the likelihood of intakes above the Tolerable Upper Intake Level. Supplement use was associated with higher mean intakes of some vitamins from foods among users than nonusers, but it was not associated with the prevalence of intakes less than the Estimated Average Requirement from foods. Those who do not use vitamin supplements had significantly higher prevalence of inadequate vitamin intakes; however, the use of supplements can contribute to excess intake for some vitamins.
