Copper sulfate. Inorganic form of copper, which is also used in supplements. However, its bioavailability may be lower compared to organic forms, and it may cause gastrointestinal irritation in some individuals.

Copper oxide. Inorganic form with the lowest bioavailability. The body absorbs it less efficiently, which is why it is less commonly used in supplements.

Symptoms and Consequences of Copper Deficiency

Copper deficiency in the human body can lead to a range of diseases and symptoms. The most common among them are anemia and cardiovascular system disorders.

Other symptoms of copper deficiency include deterioration of skin, hair, and bone tissue, as well as nervous system disorders.

Insufficient copper intake may increase the risk of developing osteoporosis and vascular diseases.

Possible Risks of Copper Excess and Toxicity

An excess of copper in the body can lead to a condition known as copper toxicity. This condition is often associated with genetic diseases such as Wilson’s disease or excessive copper intake from supplements or contaminated water.

Symptoms of copper toxicity include fatigue, headaches, vomiting, abdominal pain, and in severe cases, liver failure or mental changes.

Prolonged accumulation of copper can cause serious problems, including liver and nervous system damage.

Methods for Diagnosing and Correcting Copper Levels

Diagnosis of copper levels in the body usually involves a blood test that can determine the concentration of copper and ceruloplasmin (a protein that carries copper in the blood).

Sometimes a urine test may be required to assess copper excretion from the body.

In cases of excess copper, a doctor may prescribe chelating agents that help remove excess copper from the body.

Dietary adjustments may also be necessary to limit foods high in copper.

Impact of Copper on Other Nutrients

Iron (Fe)

Positive Influence. Copper is necessary for the proper metabolism of iron. It helps convert iron from its ferritin form to hemoglobin, which is necessary for oxygen transport in the blood.
Balance. Copper deficiency can lead to iron deficiency anemia, as the process of absorption and utilization of iron is disrupted.

Zinc (Zn)

Negative Influence. High doses of copper can inhibit zinc absorption, as they compete for the same transport pathway in the intestine.
Balance. The copper to zinc ratio should be approximately 1:8-15. For example, if you consume 1 mg of copper, you need to consume 8-15 mg of zinc to avoid imbalance.

Molybdenum (Mo)

Negative Influence. Molybdenum and copper can competitively affect each other’s absorption. High levels of molybdenum may contribute to copper deficiency.
Balance. While the exact ratio is not established, it is important to maintain moderate levels of both microelements and avoid excessive intake of either.

Vitamin C

Positive Influence. Vitamin C helps improve copper absorption, as it promotes its conversion into an easily absorbable form.
Balance. The necessity for a specific ratio is not established, but adequate vitamin C intake supports effective copper utilization in the body.

Sulfur (S)

Negative Influence. Sulfur in the form of sulfates can bind copper and hinder its absorption.
Balance. It is important to avoid excessive consumption of sulfur-rich foods if you have copper level issues.

Interesting Facts

Copper in the Brain. There is a large amount of copper in the brain, especially in the area responsible for processing thoughts and memories.

However, the largest amount of copper, about 10-15%, is found in the liver.

Antibacterial Properties. Copper has antibacterial properties and can be used to disinfect water.

Culinary Uses of Copper. Copper cookware is popular among chefs due to its ability to evenly distribute heat.

Modern copper cookware is usually covered with a protective layer, making it safe for use, unlike unprotected copper cookware from the past, which could leach toxic amounts of copper into food.

Ancient Discovery. Copper was one of the first metals that humans learned to mine and use, approximately 10,000 years ago.

The most important thing about CopperWatch all

Why does a vegetarian diet lead to zinc deficiency?

How to remove excess copper from the body?

Copper is excreted through the liver and kidneys.

To excrete copper through the kidneys, potassium and sodium (salt) are needed.

To excrete copper through the liver, cholesterol is required - this includes oil, lard, fatty meat, and cheese.

Additionally, phospholipids are necessary to maintain bile when excreting copper.

This primarily includes lecithin, for example, from eggs.

But that's not all.

Amino acids such as lysine, cysteine, glutamine, N-acetylcysteine, taurine, as well as B vitamins, bitters, and fats are also needed for bile synthesis.

All of this is part of the detoxification program from toxic metals.

Sodium and potassium play an important supporting role in the process of eliminating copper (and any toxins in general) through the kidneys. But they do not directly displace copper – they create conditions for the excretion system to work effectively. Antagonists are important for actively displacing excess copper from tissues — for example, zinc, molybdenum, sulfur (amino acids), and sometimes magnesium.

Excretion through the kidneys. Copper in the body is mainly excreted through bile (liver and intestines), but some of it can be excreted through the kidneys. Sodium and potassium regulate water-salt balance, pressure in the renal glomeruli, and kidney function as a whole. If there is a deficiency of sodium or potassium, filtration worsens, and the excretion of toxins, including copper, slows down.

In addition, potassium and sodium help maintain the normal functioning of cellular pumps (Na⁺/K⁺-ATPase), which are involved in regulating ions in the cell — their deficiency complicates the normal exchange of minerals.

The main pathway for copper excretion is through the liver into bile. For the normal synthesis of bile, activation of liver function, and transport of fat-soluble toxins (including copper), the following are important:

Cholesterol — the basis for the synthesis of bile acids;
Fats (natural saturated and monounsaturated) — formation and secretion of bile. With a deficiency of fats, bile synthesis is disrupted, and copper excretion slows down.
Phospholipids (lecithin — phosphatidylcholine) — a key component of bile, without sufficient amounts of which bile becomes too viscous, thick, poorly drains, leading to stagnation (dyskinesia, cholestasis), and stones. Eggs — one of the best sources of natural lecithin. Lecithin is also found in: liver, caviar, soybeans (soy lecithin — an industrial source), sunflower;
Lysine — synthesis of liver proteins;
Cysteine — the basis for glutathione formation;
N-acetylcysteine (NAC) — a precursor of cysteine, well absorbed, stimulates glutathione;
Glutamine — supports mucous membranes, detoxification processes, and amino acid synthesis;
Taurine — directly participates in the conjugation of bile acids; without it, bile becomes toxic and thick;
B1, B2, B3, B5, B6, B12, folate (B9) — cofactors in enzyme synthesis, amino acid metabolism, methylation, detoxification. B6 (pyridoxine) is particularly important — it participates in the metabolism of sulfur-containing amino acids (cysteine, methionine, taurine).
Bitter substances (stimulation of bile secretion): milk thistle, artichoke, dandelion, turmeric, bitter pepper, wormwood, ginger, chicory, etc.;
sufficient amount of water.
