The effect of phosphorus on zinc metabolism was studied in adult men receiving different calcium intakes ranging from 200 to 2000 mg/day. The diet and urinary and fecal excretions were analyzed for Zn, P and Ca. Metabolic balances of these elements were determined for several weeks in each study phase. In control studies the dietary intake was 800 mg/day and in the experimental studies it was increased to 2000 mg/day by adding sodium glycerophosphate to the constant diet. The dietary Zn intake averaged 14.5 mg/day in the different studies. These studies have shown that increasing the P intake by a factor of 2.5, from 800 to 2000 mg/day, did not affect urinary or fecal Zn excretions nor the Zn balance. Similar results were obtained on increasing the Ca intake from 200 to 2000 mg/day.
