aThe term “safe and adequate daily dietary intake” was used by the NRC (1989b) “when data were sufficient to estimate a range of requirements, but insufficient for developing [a Recommended Dietary Allowance].” This category was to be accompanied by “the caution that upper levels in the safe and adequate range should not be habitually exceeded because the toxic level for many trace elements may be only several times usual intakes.” Use of this term should not be taken to imply that the present committee considers these intakes to be safe or adequate.

bMedian for age group.

cCalculated from range (mg/day) and weight (kg) given for age groups.

dUpper limit for children and adolescents (upper age not specified).

eUpper limit for adults.
