Studies and Reviews

Iron deficiency is the single most prevalent nutritional deficiency worldwide. It accounts for anemia in 5 percent of American women and 2 percent of American men. The goal of this review article is to assist practitioners in understanding the physiology of iron metabolism and to aid in accurately diagnosing iron deficiency anemia.

Iron deficiency is the most common nutritional disorder affecting about 20-25 percent of the world's population, predominantly children and women. There is emerging evidence that depletion of iron stores may have adverse consequences for adults even in the absence of anemia. This raises issues about the most appropriate method of assessing iron status.
