Benefits of Copper
As an essential trace mineral, copper is vital for many processes in the human body.
Copper’s Health Benefits
- Energy & Metabolism: Helps enzymes produce energy, metabolize iron, and synthesize neurotransmitters.
- Connective Tissue: A cofactor for enzymes needed to form and stabilize collagen and elastin, which are crucial for healthy bones, blood vessels, and skin.
- Immune System: Supports immune function and helps defend against infections.
- Antioxidant: Part of the antioxidant enzyme superoxide dismutase, which helps protect cells from damage by harmful free radicals (oxidative stress).
- Nervous System: Essential for brain development and maintaining the nervous system.
- Blood Health: Required for the formation of red blood cells and for the absorption and use of iron.
Signs of Deficiency
The signs of copper deficiency can be varied and often affect the blood, nervous system, and connective tissues. Because these symptoms can resemble those of the other conditions (like Vitamin B12 deficiency or anemia), copper deficiency is sometimes overlooked.
The key symptoms are:
Hematological (Blood) and Immune System
Copper is essential for iron absorption and the formation of blood cells, so deficiency often manifests as:
- Anemia: Low red blood cell count often leading to:
- Fatigue and Weakness: Due to reduced oxygen transport to tissues.
- Neutropenia: A low count of neutrophils (a type of white blood cell), which can result in:
- Increased Risk of Infection/Frequent Sickness: As the immune system’s first line of defense is compromised.
Neurological System
Since copper is vital for brain function and nerve signaling, deficiency can cause serious neurological issues that may sometimes be irreversible if treatment is delayed:
- Ataxia: Loss of balance and poor coordination, which can cause an unsteady, wide-based gait (difficulty walking).
- Peripheral Neuropathy: Nerve damage in the extremities, leading to:
- Numbness and Tingling (Paresthesia): Often in the hands and feet.
- Muscle Weakness
- Cognitive Issues: In some cases, confusion, irritability, or problems with memory and learning.
Connective Tissue and Appearance
Copper plays a critical role in producing collagen and elastin:
- Osteoporosis: Weak and brittle bones, and in children, bone defects and fractures.
- Hypopigmentation: Paleness or lightened patches of skin, and hair that lacks normal pigment (premature greying or changes in hair texture/color).
- Connective Tissue Disorders: Problems with ligaments, blood vessels (like aneurysms), and skin health.
- Delayed Wound Healing.
