Copper Sources and Functions
All of the nutrient minerals work together to keep you healthy and feeling good. Here is a summary of the role of copper, a trace mineral, in your good health.
|What it does||Part of enzymes involved with energy production, nervous system function, connective tissue formation, iron metabolism; antioxidant|
|Daily needs||[Infants: 200-220 µg*] [Children: 340-890 µg†] [Men: 900 µg] [Women: 900 µg] [Pregnant: 1,000 µg] [Lactating: 1,300 µg]|
|Too Much||Liver damage|
|Foods||Whole grains, nuts, legumes, seafood, cocoa|
*The lower value is for infants up to 6 mos., higher value is for infants up to a year old.
† The first value is for children 1-3 with the amount increasing until age 18.
Just a trace
Note that the adequate daily intake of copper is given in micrograms (µg). A microgram is .0001 milligrams (mg), so it is avery small amount. Only a trace of this mineral is needed, but it is nevertheless very necessary to your good health.
Scientists and health experts have known for a long time that copper is an essential element in human nutrition, but they are learning more every day. The main functions of copper are related to its activity as a component of a number of enzymes.One of the most important of these copper enzyme functions is the production of hemoglobin, the iron-carrying protein in your blood. Other functions that involve copper enzymes includehealing of wounds and the release of energy from your cells.
Get rid of free radicals
Most of the copper found in your body is in the Cu++ form. These copper ions have the ability to easily take on and give up electrons, a trait which is important in dealing with unstable free radicals in your body.
Too little or too much
Copper deficiency is rare, since it is found in a variety of foods. Premature infants and those suffering with malnutrition are the groups most likely to suffer from a copper deficiency.
Copper toxicity is also rare, particularly from foods. However, excessive intake of copper from supplements may cause liver damage.
The upper intake level that has been established for adults for copper is 10,000 µg per day.
