KDRIs, Dietary Reference Intakes for Koreans; RNI, recommended nutrient intake.

¹⁾Percentages do not add up to 100 because of rounding.

²⁾Reference values for vitamin C per day were calculated as follows:

i, the age group in KDRIs; RNIMi, the RNI of males in the age group i; PMi, the proportion of males in the age group i; RNIFi, the RNI of females in the age group i; PFi, the proportion of females in the age group i.
