Functions

Chromium plays an important role in carbohydrate, lipid and protein metabolism. It potentiates the action of insulin in accelerating the utilization of glucose.

Sources

It is highly available in average diets.

Requirements

The exact requirements are not known. Average diets can meet the chromium requirements.

Absorption and excretion

It is readily absorbed in the small intestine. It is mobilized from the tissues in response to glucose administration. Chromium is mainly excreted in urine, a small amount in bile and feces.

Deficiency

Chromium deficiency is characterised by impaired growth and disturbances in glucose, lipid and protein metabolism.
