Because there is less information on which to base an allowance, these are not given in the main table of dietary allowances but are provided here in the form of ranges of recommended intakes. Since the toxic levels for many trace vitamins may be only several times usual intakes, the upper levels for the trace vitamins given in this table should not be habitually exceeded.
