本研究旨在：（1）评估膳食补充剂和强化食品使用的流行程度，（2）检查有和没有膳食补充剂和/或强化食品使用的维生素E摄入量的差异，（3）确定某些个体是否摄入维生素E超过可耐受的上限摄入水平（UL）。数据来自64，624人（年龄≥ 1岁; 47.4%男性），他们完成了2003-2009年日本国家健康和营养调查的一天家庭饮食评估。调查亦透过膳食评估，取得每种膳食补充剂或强化食物的牌子或通用名称的资料，包括其成分。通过2010年日本人膳食参考摄入量提供的年龄/性别特异性UL以上的人群比例估计潜在过量风险的患病率。5.8%的男性和7.7%的女性报告使用补充剂，而只有2.9%的男性和3.6%的女性报告食用强化食品。使用膳食补充剂在老年妇女中最常见，而使用强化食品在年轻妇女中最常见。膳食补充剂和强化食品的使用占最大的维生素E摄入量;然而，膳食补充剂和强化食品的使用对中位数和第95百分位摄入值的影响不大。没有一个受试者摄入的营养素超过UL。收集的数据证实，膳食补充剂和强化食品的使用对日本受试者的营养摄入量有少量贡献。
This study was performed to: (1) assess the prevalence of dietary supplement and fortified food use, (2) examine the differences in vitamin E intake with and without dietary supplementation and/or fortified food use, and (3) determine whether some individuals consume vitamin E above the tolerable upper intake level (UL). Data were obtained from 64,624 individuals (age, >= 1 y; 47.4% males) who completed a 1-d household dietary assessment that was part of the National Health and Nutrition Survey conducted in Japan, 2003-2009. The survey also obtained information on the brand or generic name of each dietary supplement or fortified food reported, including their ingredients, through dietary assessment. The prevalence of a potential risk of excess was estimated by the proportion of persons above the age-/sex-specific ULs provided by the Dietary Reference Intakes for Japanese 2010. Supplement use was reported by 5.8% of men and 7.7% of women, whereas fortified food consumption was reported by only 2.9% of men and 3.6% of women. Use of dietary supplements was most common among older women, whereas use of fortified foods was most common among younger women. Both dietary supplement and fortified food use accounted for maximum vitamin E intake; however, the use of dietary supplements and fortified foods had little effect on the median and 95th percentile intake values. None of the subjects consumed nutrients above the UL. The collected data confirm that the use of both dietary supplements and fortified foods contributes a small amount to nutrient intake in Japanese subjects.
