Neftaly: Role of Copper in Immune Function

While often overlooked, copper is an essential trace mineral that plays a vital role in maintaining a strong and responsive immune system. At Neftaly, we believe that understanding the power of micronutrients—like copper—is key to supporting lifelong health.

---

Why Is Copper Important for the Immune System?

Copper contributes to immune function by supporting several key biological processes. Although the body needs only small amounts, a deficiency—or excess—can significantly impact immune health.

Key Ways Copper Supports Immune Function

1. Enhances White Blood Cell Activity

Copper helps regulate the development and activity of white blood cells, particularly neutrophils and macrophages. These immune cells are your body’s first line of defense against infections.

---

2. Acts as a Natural Antioxidant

Copper is involved in the function of antioxidant enzymes like superoxide dismutase (SOD), which protect immune cells from damage caused by oxidative stress during inflammation or infection.

---

3. Supports Inflammation Balance

While inflammation is a necessary immune response, chronic inflammation can harm the body. Copper helps maintain balanced inflammatory responses, preventing excessive immune reactions.

---

4. Aids in Iron Metabolism

Copper helps the body absorb and transport iron, another critical nutrient for immune cell function. Copper deficiency can lead to iron-deficiency anemia, which weakens the immune system.

---

5. Maintains Barrier Integrity

Copper supports the maintenance of healthy skin and mucous membranes, which act as physical barriers to pathogens.

---

Signs of Copper Deficiency

Though rare, copper deficiency can occur due to poor diet, certain medical conditions, or excessive zinc intake. Symptoms may include:

• Frequent infections
• Fatigue or weakness
• Pale skin
• Poor wound healing
• Weak immune response

Food Sources of Copper

You can meet your copper needs by including a variety of copper-rich foods in your diet:

• Shellfish (especially oysters)
• Nuts and seeds (cashews, sunflower seeds)
• Whole grains
• Dark chocolate
• Legumes
• Organ meats (like liver)
• Leafy greens

✅ Recommended intake: Adults need about 900 micrograms of copper per day.

Neftaly Caution: Balance Is Key

Too much copper can be harmful. Avoid high-dose copper supplements unless recommended by a healthcare provider. A balanced diet is usually enough to meet your needs.
