Why is the copper-zinc balance important?

Zinc and copper compete for absorption in the intestine. Excessive zinc intake (over 40 mg daily) can cause copper deficiency and vice versa. The optimal ratio is approximately 8-15:1 zinc to copper. If you take a zinc supplement long-term, add 1-2 mg of copper to maintain balance.

What are the signs of copper deficiency?

Copper deficiency manifests as fatigue, anemia (that doesn't respond to iron therapy), frequent illness, weakened bones, and premature graying of hair. Severe deficiency can cause neurological disorders. At higher risk are those who take high doses of zinc long-term and people with malabsorption syndromes.

How much copper should you take per day?

The recommended daily amount for adults is 0.9 mg. The upper safe limit is 10 mg per day. Most people get sufficient copper from food — liver, chocolate, nuts, seeds, and legumes. Supplements are mainly needed when taking high zinc doses long-term.
