Naturopathy : Copper

There are approximately 75 to 150 mg. of copper in the adult human body. Newborn infants have higher concentrations than adults. Liver, brain, kidney, heart, and hair contain relatively high concentration. Average serum copper levels are higher in adult females than in males. Serum copper levels also increase significantly in women both during pregnancy and when taking oral contraceptives.

This mineral helps in the conversion of iron into haemoglobin. It stimulates the growth of red blood cells. It is also an integral part of certain digestive enzymes. It makes the amino acid tyrosine usable, enabling it to work as the pigmenting factor for hair and skin. It is also essential for the utilisation of vitamin C. Copper is found in most foods containing iron, especially in almonds, dried beans, peas, lentils, whole wheat, prunes and egg yolk. The recommended dietary allowance has not been established but 2 mg. is considered adequate for adults. A copper deficiency may result in bodily weakness, digestive disturbances and impaired respiration.

Copper and zinc absorption is closely related, and although copper is also needed in relatively small amounts, some discussions are under way on the optimum need of this mineral. If large amounts of copper are present, then zinc and vitamin C is reduced in the body, and vice versa.

Copper is required for

Copper is required in the formation of hemoglobin, red blood cells as well as bones, while it helps with the formation of elastin as well as collagen - making it necessary for wound healing.

A lack of copper may also lead to increased blood fat levels. It is also necessary for the manufacture of the neurotransmitter noradrenaline as well as for the pigmentation of your hair.

Deficiency of copper

It can be stored in the body, and daily presence in the diet is therefore not necessary. If copper is deficient in the body, iron is also normally in short supply, leading to anemia as well as the likelihood for infections, osteoporosis, thinning of bones, thyroid gland dysfunction, heart disease as well as nervous system problems.

Dosage

The dosage is the Recommended Daily Allowance (RDA), but be aware that this dosage is the minimum that you require per day, to ward off serious deficiency of this particular nutrient. In the therapeutic use of this nutrient, the dosage is usually increased considerably, but the toxicity level must be kept in mind.

In the case of micro-elements, such as trace elements, the amounts are very small, yet they are still important and about 2 mg per day is required.

Toxicity and symptoms of high intake

Toxic levels will lead to diarrhea, vomiting, liver damage as well as discoloration of the skin and hair, while mild excesses will result in fatigue, irritability, depression and loss of concentration and learning disabilities.

Children getting too much copper may have hyperactive tendencies.

Best used with

Copper is best absorbed and utilized in the body when cobalt, iron, zinc and folic acid is available.

When more copper may be required

Should extra zinc supplements be taken, your need for copper may be increased.

Enemy of copper

The absorption of large amounts of vitamin C, zinc can negatively influence the level of copper in the body, while large amounts of fructose can make a copper deficiency worse.

Other interesting points

Be careful of having any liquids stored in copper containers, as the liquid could have absorbed too much of the copper.

Food sources

Copper is made available from a variety of foods, such as whole grain, liver, molasses, and nuts, but water from copper pipes will also carry copper in it, and copper cooking utensils will also add more copper to be ingested.
