From the Guidelines

Your zinc to copper ratio of 11.1:1 (1287:116) is significantly elevated, suggesting zinc dominance and potential copper deficiency, which may lead to symptoms like fatigue, anemia, weakened immunity, and neurological issues, and therefore, reducing zinc supplementation and increasing copper intake is recommended. To address this imbalance, consider reducing zinc supplementation if you're taking any, while potentially increasing copper intake through foods like organ meats, shellfish, nuts, and dark chocolate 1. A healthcare provider might recommend copper supplementation (typically 1-3mg daily) to restore balance, as the optimal ratio of zinc to copper should be maintained to avoid zinc-induced copper deficiency, with a recommended ratio of 8–15 mg of zinc for each 1-mg copper 1.

Some key points to consider:

  • High zinc levels can interfere with copper absorption and utilization, leading to copper deficiency 1
  • Copper deficiency can cause symptoms like fatigue, anemia, weakened immunity, and neurological issues 1
  • Regular monitoring with follow-up testing is advisable to track progress toward a healthier mineral balance 1
  • The current complete multivitamin and mineral available on prescription (Forceval) in the United Kingdom contains 2-mg copper and 15-mg zinc, and doubling up on the dosage may be sufficient in some cases to meet the additional requirements 1

It is essential to interpret laboratory testing alongside clinical symptoms, as this imbalance affects numerous bodily processes since both minerals are essential cofactors for enzymes involved in energy production, antioxidant defense, and neurotransmitter synthesis 1.

From the Research

Zinc to Copper Ratio Implications

The provided zinc and copper values are 1287 and 116, respectively. To understand the implications of this ratio, we need to examine the available evidence.

  • The zinc to copper ratio is an important aspect of human health, with various studies investigating its effects on different physiological processes 2.
  • A study published in 2015 found that the serum copper to zinc ratio increases with aging and is associated with inflammatory conditions, suggesting that this ratio may be a useful marker for age-related chronic diseases 2.
  • However, the provided evidence does not directly address the specific zinc and copper values mentioned in the question.
  • It is known that excessive zinc intake can inhibit the absorption of copper, leading to copper deficiency 3.
  • The recommended daily intake of zinc and copper varies, with studies suggesting that zinc fortification of staple foods could be 20-50 mg/kg of flour, and copper fortification could be 1.2-3.0 mg/kg of flour 4.
  • Zinc supplementation can also affect copper levels in the body, with one study finding that zinc inhibits intestinal copper uptake 5.

Potential Health Implications

  • The high zinc value and relatively low copper value may indicate an imbalance in the zinc to copper ratio.
  • This imbalance could potentially lead to copper deficiency, as excessive zinc intake can inhibit copper absorption 3.
  • However, without more information on the individual's health status and dietary habits, it is difficult to determine the exact implications of this ratio.
  • Further research is needed to fully understand the effects of this zinc to copper ratio on human health.
