“…Some limitations should also be addressed. First, all estimates of dietary intake assume that reported nutrient intake from food sources on the 24-h recalls are unbiased and that the selfreported dietary supplement intake reflects true long-term (27,28). For calcium, the average deviation from the label is 14% (29); information on vitamin D deviation from label is not known at this time.…”

Our objective in this study was to estimate calcium intakes from food, water, dietary supplements, and antacids for U.S. citizens aged >or=1 y using NHANES 2003-2006 data and the Dietary Reference Intake panel age groupings. Similar estimates were calculated for vitamin D intake from food and dietary supplements using NHANES 2005-2006. Diet was assessed with 2 24-h recalls; dietary supplement and antacid use were determined by questionnaire. The National Cancer Institute method was used to estimate usual nutrient intake from dietary sources. The mean daily nutrient intake from supplemental sources was added to the adjusted dietary intake estimates to produce total usual nutrient intakes for calcium and vitamin D. A total of 53% of the U.S. population reported using any dietary supplement (2003-2006), 43% used calcium (2003-2006), and 37% used vitamin D (2005-2006). For users, dietary supplements provided the adequate intake (AI) recommendation for calcium intake for approximately 12% of those >or=71 y. Males and females aged 1-3 y had the highest prevalence of meeting the AI from dietary and total calcium intakes. For total vitamin D intake, males and females >or=71, and females 14-18 y had the lowest prevalence of meeting the AI. Dietary supplement use is associated with higher prevalence of groups meeting the AI for calcium and vitamin D. Monitoring usual total nutrient intake is necessary to adequately characterize and evaluate the population's nutritional status and adherence to recommendations for nutrient intake.

“…No dietary supplement database was available, and labelled values have limitations (Dwyer et al, 2007), particularly if collected years after the original data collection. However, it is likely that the food-based intakes of minerals , water-soluble vitamins , fat-soluble vitamins and polyunsaturated fatty acids (Linseisen et al, 2009) from the EPIC calibration study underestimate the actual total nutrient intakes, given that the contribution from supplements is not included.…”

Background: Dietary supplement use is increasing, but there are few comparable data on supplement intakes and how they affect the nutrition and health of European consumers. The aim of this study was to describe the use of dietary Correspondence: G Skeie, Institute of Community Medicine, University of Tromsø, N-9037 Tromsø, Norway.

The other co-authors were local EPIC collaborators involved in the design of the study and data collection. ER is the overall coordinator of the EPIC study. All co-authors provided comments and suggestions on the article and approved the final version. Results: Between countries, the mean percentage of dietary supplement use varied almost 10-fold among women and even more among men. There was a clear north-south gradient in use, with a higher consumption in northern countries. The lowest crude mean percentage of use was found in Greece (2.0% among men, 6.7% among women), and the highest was in Denmark (51.0% among men, 65.8% among women). Use was higher in women than in men. Vitamins, minerals or combinations of them were the predominant types of supplements reported, but there were striking differences between countries. Conclusions: This study indicates that there are wide variations in supplement use in Europe, which may affect individual and population nutrient intakes. The results underline the need to monitor consumption of dietary supplements in Europe, as well as to evaluate the risks and benefits.

“…In the U.S., the Food and Nutrition Board of the Institute of Medicine (IOM) is responsible for specifying national nutrient requirements as well as tolerable upper intake levels of essential nutrients to avoid adverse effects [25]. However, these national requirements are often ignored by DS manufacturers who include larger amounts of nutrients in their products than recommended by the IOM [26,27].…”

Patterns of dietary supplement use among college students

College students appear more likely to use DS than the general population and many use multiple types of supplements weekly. Habits established at a young age persist throughout life. Therefore, longitudinal research should be conducted to determine whether patterns of DS use established early in adulthood are maintained throughout life. Adequate scientific justification for widespread use of DS in healthy, young populations is lacking.
