Overview

Zinc is an essential trace mineral necessary for numerous biological functions, including immune system support, DNA synthesis, cell division, and protein synthesis. It is vital for growth and development, wound healing, and the sense of taste and smell. Zinc also plays a role in enzymatic reactions, acting as a cofactor for over 300 enzymes in the human body. Zinc is absorbed in the small intestine and transported throughout the body to be utilized in various physiological processes. Zinc deficiency can lead to impaired immune function, delayed wound healing, hair loss, and skin lesions. Conversely, excessive zinc intake can interfere with the absorption of other essential minerals, such as copper, and may cause gastrointestinal distress. Measuring zinc levels can help diagnose deficiencies or toxicities and guide appropriate dietary and supplemental interventions.

Testing Levels:

  • High (16.8 μmol/L) - Elevated zinc levels, though uncommon, can result from excessive supplementation or exposure to zinc through occupational or environmental sources. High zinc levels can interfere with the absorption of other essential minerals, particularly copper, and may cause symptoms like nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. Long-term high zinc intake can lead to copper deficiency and associated anemia and neurological issues. It is important to identify the source of excess zinc and reduce exposure or supplementation.

  • Mid - Normal zinc levels indicate adequate intake and absorption, supporting numerous physiological functions such as immune response, wound healing, and enzymatic activity. This balance reflects a well-rounded diet and effective metabolic processes, ensuring overall good health.

    Zinc levels near the upper limit may suggest a high dietary intake or recent supplementation. While these levels are not typically harmful, monitoring intake to prevent excessive levels is advisable. Ensuring a balanced diet without over-reliance on supplements can help maintain zinc within a healthy range.

    Zinc levels near the lower end may indicate a marginal deficiency, which could be due to inadequate dietary intake, mild malabsorption issues, or increased physiological demands (such as during growth, pregnancy, or recovery from illness). Monitoring these levels and considering dietary adjustments or supplementation can help maintain proper zinc status.


  • Low (10.1 μmol/L) - Low zinc levels indicate a deficiency, which can result from poor dietary intake, malabsorption syndromes, chronic diseases, or increased losses (such as through sweat or chronic diarrhea). Symptoms of zinc deficiency include impaired immune function, delayed wound healing, hair loss, skin lesions, and taste abnormalities. Addressing the underlying cause and supplementing zinc are essential steps to restore normal levels and prevent complications.

Why We Test Zinc

Measuring zinc levels is crucial for diagnosing deficiencies or toxicities that can impact immune function, wound healing, growth, and overall health. It provides valuable insights into nutritional status and helps guide dietary and supplemental interventions. Regular monitoring is particularly important for individuals with symptoms of zinc imbalance, gastrointestinal disorders, or those at risk for malnutrition. Maintaining zinc levels within the normal range is essential for supporting critical bodily functions and preventing complications related to both deficiency and excess.

What Affects It

Factors influencing zinc levels include dietary intake, absorption efficiency, chronic diseases, gastrointestinal disorders, infections, stress, and certain medications such as diuretics and antibiotics. Conditions like malnutrition, alcoholism, and chronic kidney or liver disease can also impact zinc levels.

How to Improve

For high zinc levels, reducing dietary intake, avoiding unnecessary supplementation, and identifying environmental sources of excess zinc are crucial. For levels close to being high, similar monitoring and dietary adjustments are important. For low zinc levels, increasing dietary intake of zinc-rich foods (such as meat, shellfish, legumes, seeds, and nuts) and addressing underlying causes of malabsorption or increased losses can help. For levels close to being low, ensuring adequate intake through a balanced diet and possibly supplementing zinc can maintain optimal levels. Regular monitoring and consultation with a healthcare provider ensure that zinc levels remain within the optimal range.
