ABSTRACT
The use of isotopic tracers for research on copper in humans has resulted in new, definitive information that aids in developing an understanding of the metabolism of copper. In recent years, most studies of copper metabolism in humans have been conducted with stable-isotope tracers, but radioisotopes were used in early tracer studies and in select recent studies. Isotopic tracers
can be used in conjunction with traditional indices of copper status to gain a better understanding of a variety of areas related to copper nutriture.
