1. What is Copper and Why Do We Need It?
Copper is a vital trace mineral that plays a crucial role in numerous bodily functions. Your body uses copper for energy production, iron metabolism, neuropeptide activation, connective tissue synthesis, and neurotransmitter production, as stated in research from the National Institutes of Health (NIH). Without enough copper, your body can’t function optimally.
What are the Primary Functions of Copper in the Body?
Copper supports several critical physiological processes. Here are some key functions:
- Energy Production: Copper is a component of enzymes involved in producing cellular energy.
- Iron Metabolism: It helps in the absorption and utilization of iron, preventing anemia.
- Connective Tissue Formation: Copper is essential for synthesizing collagen and elastin, which maintain the integrity of skin, blood vessels, and bones.
- Nerve Function: It aids in the proper functioning of nerves by participating in neurotransmitter synthesis.
- Immune Function: Copper supports the immune system, helping the body defend against infections.
How Much Copper Do We Need Daily?
The Recommended Dietary Allowance (RDA) for copper varies depending on age, sex, and life stage. According to the Food and Nutrition Board (FNB) at the National Academies of Sciences, Engineering, and Medicine:
- Adults (19+ years): 900 mcg
- Pregnant Women: 1,000 mcg
- Lactating Women: 1,300 mcg
Ensuring you meet these daily requirements is essential for maintaining optimal health.

How Does Copper Contribute to Bone Health?
Copper is essential for synthesizing collagen, a key component of bone tissue. It helps maintain bone strength and prevent osteoporosis and other bone defects, as noted in studies on copper deficiency.
4. What Happens if You Don’t Get Enough Copper?
Copper deficiency is relatively uncommon, but it can lead to several health issues if left unaddressed.
What are the Symptoms of Copper Deficiency?
Symptoms of copper deficiency can include:
- Anemia: Due to copper’s role in iron metabolism.
- Hypopigmentation: Lightening of the skin and hair.
- High Cholesterol: Abnormal lipid metabolism.
- Connective Tissue Disorders: Problems with the integrity of tissues like skin and blood vessels.
- Osteoporosis: Weak and brittle bones.
- Ataxia: Loss of coordination.
- Increased Risk of Infection: Due to impaired immune function.
Who is at Risk of Copper Deficiency?
Certain groups are more susceptible to copper deficiency:
- Individuals with Celiac Disease: Malabsorption issues can lead to deficiencies.
- People with Menkes Disease: A genetic disorder affecting copper absorption.
