‘Weekly users” plus “daily users” were defined as “regular users”.
Seven males and 22 females were excluded from the analysis because they reported uncertainty about the information on dietary supplement intake.
Some products in which nutrient content was not described were excluded when we developed the database and we did not calculate nutrient intake from these products.
* : Results from the National Nutrition Survey in Japan, 2002 (mean of the total).
† : Tolerable upper intake level of adults in 6th edition or 2005 edition of Nutrient-Based Dietary Reference Intakes in Japan.
- : Tolerable upper intake level of adults in 6th edition or 2005 edition of Nutrient-Based Dietary Reference Intakes in Japan was not shown.
‡ : Number of participants who daily consumed some nutrients at more than the tolerable upper intake level in the 6th Edition or 2005 Edition of Nutrient-Based Dietary Reference Intakes (DRIs) in Japan.
§ : Below display limit
