  5. # Averaged over 3 days, assuming production of creatinine is 500 mcg/day, which is typical for a 60-pound child
  6. N = 63. Units are mg/g-creatinine (note difference from table 2 and 3, which are mcg/g-creatinine). Arranged in approximate order of increase in urinary excretion. The extra loss of minerals due to increased urinary excretion is also listed in terms of the RDA. Results for potassium (K) and chromium (Cr) are highlighted due to the large % of RDA.
