Introduction

Copper is one of the essential trace minerals required for plant, animal and human health.

It is the third most abundant trace metal in the human body after iron and zinc [3].

Copper works with iron to help the body form red blood cells[1,4].

  • Copper is absorbed in the gut and transported to the liver[3].
  • Copper absorption varies with intake, absorption rate is around 50% when intake is less than 1 mg/day and less than 20% when consumption is more than 5 mg/day[2].
  • An average adult has around 50-120 mg of copper reserves and almost two-thirds of the body’s copper is located in the skeleton and muscles [1,2].
  • It can take several years before copper reserves are depleted from the body[5].
  • Most copper is excreted in bile and a small amount in urine[1]
  • Total faecal losses of copper of biliary origin and non-absorbed dietary copper are about 1 mg/day [1].
