Zinc, the most abundant intracellular element, is found in all body tissues, with ∼85% of the whole body zinc in muscle and bone . Another 11% is found in the skin and liver. The remaining 2–3% of the whole body zinc is in all of the other tissues (Jackson 1989).

May 01, 2000 Central to maintenance of zinc homeostasis, however, is the gastrointestinal system, especially the small intestine, liver and pancreas. Specifically, both the processes of absorption of exogenous zinc and gastrointestinal secretion and excretion of endogenous zinc are critical to whole body zinc homeostasis.

Zinc is hypothesized to play a role in the development of AMD for several reasons: (1) zinc is found at high concentrations in the part of the retina affected by AMD, (2) retinal zinc content has been shown to decline with age, and (3) the activities of some zinc-dependent retinal enzymes have been shown to decline with age.

About 70% of the zinc in circulation is bound to albumin, and any condition that alters serum albumin concentration can have a secondary effect on serum zinc levels. Although, serum zinc represents only 0.1% of the whole body zinc, the circulating zinc turns over rapidly to meet tissue needs.[6,10,11]

When zinc deficiency does occur, it is usually due to inadequate zinc intake or absorption, increased losses of zinc from the body, or increased requirements for zinc [27,28,35]. People at risk of zinc deficiency or inadequacy need to include good sources of zinc in their daily diets.
