Exchangeable Zinc Pool Masses and Turnover Are Maintained in Healthy Men with Low Zinc Intakes1,2

ABSTRACT Previous studies suggest that rapidly exchanging zinc pools (EZP), thought to supply the zinc required by tissues, are smaller and turn over more rapidly in individuals with lower zinc intakes. We studied the effects of low dietary zinc (4.6 mg/d) on UP mass and turnover in seven healthy men confined during a 20-wk clinical study. Supplements of 9.1 mg zinc were given during the 5-wk baseline and repletion periods, and placebos were given during a 10-wk zinc-restriction period. Stable ^sup 70^Zn tracers were administered intravenously at the end of baseline, 3 and 10 wk after the ...
