Utilization of phosphorus and magnesium by 11 girls (12.5‐14.2 yr of age) was measured during a 30‐day period in which two different levels of zinc (11.5 and 14.7 mg daily) were fed. The former level is similar to that consumed usually by adolescent females; the latter level is similar to the Recommended Dietary Allowance for zinc. Apparent retention of phosphorus was reduced significantly (p < 0.02) when subjects were fed the higher level of zinc. Both urinary and fecal phosphorus levels were greater, but not significantly greater, when subjects consumed the higher level of zinc. The variations in dietary zinc levels had no effect on magnesium utilization.
