aBecause there is less information on which to base allowances, these figures are not given in the main table of RDA and are provided here in the form of ranges of recommended intakes.

bBecause the toxic levels for many trace elements may be only several times usual intakes, the upper levels for the trace elements given in this table should not be habitually exceeded.

aNo allowance has been included for large, prolonged losses from the skin through sweat.

bThere is no evidence that higher intakes confer any health benefit.

cDesirable intakes of potassium may considerably exceed these values (3500mg for adults).

dNo allowance included for growth. Values for those below 18 years assume a growth rate at the 50th percentile reported by the National Center for Health Statistics (Hamill et al., 1979) and averaged for males and females.
