Copper helps in bone
and connective tissue formation

How does copper work?

Copper allows iron to be fixed in hemoglobin, a component of red blood cells present in the blood. Red blood cells are responsible for transporting oxygen from the lungs to the tissues and organs.

Copper participates in the formation of bones and connective tissue and is important for the proper function of the immune system. This mineral is also involved in the pigmentation of skin and hair.

Copper in the diet

Foods rich in copper include offal, fish, shellfish, grains and nuts. Also vegetables, fruit and chocolate contain copper, albeit in smaller quantities.

Lack of copper

A deficiency of copper hardly ever occurs, but a reduced consumption of foods can affect the levels found in the body. Among the possible problems include anemia, decreased resistence to illnesses and abnormalities of the bones, such as osteoporosis.

Excess copper

In adults the safe upper limit for this mineral is equal to 5 mg per day. This amount corresponds to 550 grams of boiled rice.

Any excess copper can be caused by the consumption of food and / or contaminated beverages. Pain in the abdomen, nausea, vomiting and diarrhoea are the symptoms associated with an excessive intake of copper.

Following the placement of a gastric band or sleeve

If you underwent surgery for placement of gastric banding or sleeve it is important to take a daily amount of copper equal to 0.9 milligrams. This value corresponds to 100% of the Recommended Daily Allowance.

Following gastric bypass surgery, duodenal switch or biliopancreatic diversion procedures

Because changes made to the small intestine as a result of this type of intervention your need for copper increases. This is due to the fact that the tract of the intestine through which copper is absorbed is bypassed following surgery, so that assimilation of copper by the body becomes insufficient. Therefore, it is necessary to take more than 3 milligrams, or 300% of the Recommended Daily Requirement to provide your body with an adequate daily intake.

Copper supplements

The absorption of copper via the daily diet may be affected by excessive consumption of iron, zinc and vitamin C. In the case of a high consumption of foods that contain these vitamins and minerals you can use a copper supplement to complement your diet.

WLS Optimum and WLS Forte supplements can offer an adequate amount of copper through taking just capsule per day. For more information, please refer to our homepage:
