What is copper and why is it essential for the body?
Copper is an essential trace element that plays a fundamental role in many biological functions. Present in minute quantities in the human body, it is involved in the formation of red blood cells, the proper functioning of the immune system and the production of cellular energy.
Copper is also a powerful antioxidant, helping to neutralize the free radicals responsible for cell aging and numerous degenerative diseases.
What are the health benefits of copper?
The right amount of copper in the body provides a number of essential benefits:
Immune system support: stimulates immune cell production and helps fight infection.
Energy production: participates in carbohydrate and lipid metabolism, promoting better utilization of nutrients.
Bone and joint health: involved in collagen synthesis, contributing to bone strength and prevention of osteoarthritis.
Protection of the cardiovascular system: regulates blood pressure and promotes healthy blood vessels.
Powerful antioxidant: protects cells against oxidative stress and limits damage associated with premature aging.
Skin and hair pigmentation: promotes melanin synthesis, helping to maintain radiant skin and healthy hair.
What are the symptoms of copper deficiency?
Copper deficiency, although rare, can have significant health consequences, including:
Excessive fatigue and a feeling of persistent weakness.
Anemia due to reduced iron absorption.
Neurological disorders: loss of coordination, muscle weakness and numbness.
Osteoporosis and joint pain caused by bone fragility.
Weakening of the immune system: increased susceptibility to infections.
Skin and hair depigmentation, which can lead to premature bleaching.
What are the best dietary sources of copper?
As copper is an essential trace element, it must be supplied through the diet. The main natural sources include
Offal: veal liver, poultry liver, kidneys.
Seafood: oysters, mussels, shrimps.
Oilseeds: cashew nuts, almonds, hazelnuts.
Wholegrain cereals: quinoa, rolled oats, wholemeal bread.
Legumes: lentils, chickpeas, kidney beans.
Dark chocolate: rich in copper, it also offers antioxidant benefits.
A varied, balanced diet is generally sufficient to cover daily copper requirements.
What are the risks of excess copper in the body?
While copper deficiency can be problematic, excess can also have negative consequences. Excessive accumulation of copper in the body can cause :
Digestive disorders: nausea, vomiting, abdominal pain.
Oxidative stress: excessive formation of free radicals, promoting inflammation.
Neurological disorders: anxiety, insomnia and mood disorders.
Excess copper may be due to excessive consumption of dietary supplements, or to certain genetic diseases such as Wilson's disease, which leads to a toxic accumulation of copper in the liver and brain.
Is copper good for skin and hair?
Yes, copper is an essential ally for beautiful skin and hair. It plays a key role in collagen and elastin synthesis, contributing to firmer, more elastic skin. Moreover, by promoting melanin production, it helps preserve hair's natural pigmentation and prevent premature bleaching.
Can copper help fight infection?
Absolutely! Copper has antimicrobial and antiviral properties. It has been used since Antiquity for its purifying properties, particularly in disinfecting water and wounds. Even today, copper is found in certain antibacterial materials used in hospitals to limit the spread of infections.
Do copper requirements vary according to age and sex?
Yes, copper requirements vary according to several factors:
Infants (0-6 months): 0.2 mg/day
Children (1-8 years): 0.3 to 0.7 mg/day
Adolescents and adults: 0.9 mg/day
Pregnant and breast-feeding women: 1 to 1.3 mg/day
Pregnant and breastfeeding women have increased copper requirements, as this trace element is crucial for fetal and infant brain development.
Can copper improve memory and concentration?
Yes, copper plays a fundamental role in the transmission of nerve signals and the formation of new neuronal connections. A copper deficiency may be associated with cognitive problems, including impaired memory and concentration.
Studies suggest that adequate copper intake may help prevent neurodegenerative diseases such as Alzheimer's and Parkinson's.
How are copper and iron linked in the body?
Copper and iron are two interdependent trace elements. Copper is essential for the absorption and transport of iron in the body. A copper deficiency can lead to iron-deficiency anemia, even in the presence of an adequate iron intake.
To avoid deficiencies, it is important to adopt a balanced diet rich in these two minerals.
Is copper used in medicine and naturopathy?
Yes, copper is widely used in natural medicine and naturopathy for its anti-inflammatory, immunostimulant and antimicrobial properties. It can be found in several forms:
Trace elements in ampoules to boost the immune system.
Copper bracelets used to relieve joint pain.
Colloidal copper recognized for its antibacterial and antifungal properties.
