Do you have a high copper to zinc ratio?

Is your Anxiety or PMS caused by high Copper to zinc ratio?

Copper and zinc are two important minerals in our body and required for a multitude of functions and processes. Zinc (Zn) deficiency and copper (Cu) excess are common clinical scenarios in both Australia and worldwide causing a high copper to zinc ratio.

A high Copper to Zinc ratio (Cu/Zn) can cause a range of detrimental health effects including growth and mental abnormalities, increased age degeneration, contribute toward cancer progression and increase oxidative stress and cardiovascular disease risks.

Both copper (Cu) and zinc (Zn) are antagonistic to each other, meaning the more of one element you retain the less of the other you will have in your body. The ratio between copper and zinc is a fine balance and one that is commonly being tipped toward copper in modern society to the detriment of our health.

Copper Excess

Excess copper is far more common that Cu deficiency in Australia. Highly farmed lands are often high in Cu and low in Zn, water pipes, drinking water, pesticide residue and Cu added to animal feedlots are all forms of exposure that over time artificially increase our levels of this mineral.

On the other hand, Zn is estimated to be deficient in over 50% of the population despite it being supposedly available in many foods. Again, poor farming methods and low quality food, nutrient imbalances with high Cu, low stomach acid reducing the adsorption of Zn and metabolic processes that use up our Zn stores leaving us low are all common reasons many of us are Zn deficient.

Physical low Zn signs include slow healing wounds, dry and poor quality skin, white spots on finger nails, poor smell and taste and an intolerance to loud sounds.

Symptoms of High Copper and low Zinc

• Anxiety, panic attacks, general inner tension
• Despair and depression
• Fatigue
• Hypothyroid symptoms (cold hands and feet, brain fog, dry skin)
• Overly sensitive, obsessive thinking
• insomnia, interrupted sleep
• Fluctuating blood sugar causing cravings
• Mood swings, Paranoia
• Constipation
• Racing heart / palpitations
• Adverse reaction to vitamins and minerals ( due to copper dumping from the supplements )
• Poor attention span / spacey feeling
• Eating disorders (anorexia, bulimia, overeating)
• Yeast infections (candida and fungus)
• Cramping and body aches

Conditions associated with high Copper to Zinc ratio

Excess Copper is associated with a range of mental and behavioural disorders, it can contribute to the symptoms of depression, panic attacks, anxiety, fearfulness, excessive anger and schizophrenia.

Other conditions associated with excess copper include premenstrual syndrome (PMS), gallstones, viral infections, scoliosis, yeast and fungus overgrowth. Viral, yeast and fungal infections all thrive in a high Cu and low Zn environment. Viral infections lower a person’s metabolic rate promoting the retention of copper.

A low zinc level is involved with sleep disturbances, depression and other mood disorders. Zinc is required in both the production of melatonin and serotonin. Without adequate zinc we cannot create sufficient levels of these to allow for restful sleep and a well-balanced stable mood. A low level of zinc is also associated with various skin conditions, sickle cell anaemia, diabetes and anorexia.

In relation to PMS, as the copper levels rise within the body so does estrogen. Low levels of Zn cause imbalances with progesterone, testosterone and further compound the increase in estrogen that Cu causes.

Pyrrole disorder is a common condition that highlights many of the mood related symptoms outlined above. Pyrrole disorder causes a deficiency of both Zn and B6, another vitamin crucial in neurotransmitter support. Pyrrole disorder sufferers almost always have excess Cu and require ongoing Zn and B6 supplementation. It is estimated at least 10% of children have pyrrole disorder and as high as 30-40% of the population that suffers from mental disorders.

We regularly deal with clients with Pyrrole disorder and others than have elevated Cu levels. More information on pyrrole disorder and a symptom checklist, please follow this link.

Studies – Behavioural Disorders in Children

A number of studies have been performed on kids with elevated Cu levels and their mood, attention and learning ability. One study focused on a group of 49 young children with an average age of 10.

The study found that the children with aggressive behavioural disorders all had a high Cu/Zn ratio when compared to a control group of similar aged children without behavioural disorders.

The study also found that those children with the most violent and disruptive behavioural patterns had the highest Cu/Zn ratios in the group. (1)

Furthermore, four separate outcome studies were conducted where nutrient therapy was administered to children with behavioural disorders. Biochemical nutrient therapy focuses on restoring nutritional balance with vitamins, minerals and amino acids such as zinc, vitamin B6, magnesium, methionine and vitamins C and E.

The four outcome studies found that out of the 207 participants, 88% of the people reported a reduced frequency of destructive behaviour and 53% of these had totally eliminated their destructive behaviours. (2)

In addition, a high Cu/Zn ratio was found to be linked to heavy metal accumulation and found to be a possible biomarker in those with autism spectrum disorder. When zinc levels are depressed, opportunistic heavy metals accumulate in the brain and body causing a wide range of adverse symptoms. (3)

Studies – Advanced Aging and Degenerative disease

A study was conducted on 81 healthy and 62 unwell individuals in their 90’s who were affected by chronic degenerative disease. The purpose was to assess the effect of a high Cu/Zn ratio on aging and age related degenerative disease by measuring the blood content of copper and zinc. The serum Cu/Zn ratio were found to be all significantly higher in the elderly with chronic degenerative disease over the elderly without.

The study concluded that there is a strict relationship between copper and zinc and the systemic oxidation and ageing of the body. Furthermore, it was suggested that a high Cu/Zn ratio be a useful predictive biomarker for poor health in the elderly. (4)

Another study also measured the plasma Cu/Zn ratio and measured various inflammatory markers of 498 people aged between 20 and 60. Subjects with cardiovascular disease all had higher plasma Cu/Zn ratios than those without, mainly due to increased plasma Cu.

In other subjects, most of the age related health decline appeared to be from a progressive decline in plasma Zn levels. The study highlights the importance of the levels of zinc in the body and the detrimental health effects when the Cu/Zn ratio is high. (5)

The role of both zinc and copper are of the utmost importance. Zinc is essential for healthy immune function, the reproductive system, normal growth and development and a range of other functions. It is also a major mineral for hormone production and is a copper antagonist.

Copper is required for a healthy nervous system, bones, joints, skin, blood vessels, mood regulation and myelin sheath formation. When levels become too high, particularly when zinc is low, toxic effects on the body can be observed.

Zinc is commonly low when copper is high as copper has a strong antagonistic effect on zinc. This imbalance appears to play a contributing role in many mental diseases including schizophrenia, anxiety, depression, ADD, as well as many other degenerative diseases related to oxidative stress including advanced ageing and cardiovascular disease.

Cancer formation can be found within studied patients that had high Cu/Zn ratios, again suggesting the oxidative and biochemical disruption high Cu/Zn has on the body.

Functional Testing

If some of the above symptoms resonate with you of your family members, it would be wise to have your Cu and Zn levels tested. Common blood test result ranges that are considered ok are not sufficient to go by, the amount of Cu in relation to zinc and ceruloplasmin is required to be calculated. Ceruloplasmin, a copper transport protein, should also be tested at the same time that Cu and Zn blood levels are taken to able to calculate the amount of unbound copper in the system.

We also commonly use a hair mineral analysis or other spectrometry scan to assist in giving a full mineral profile and a longer term picture as mineral levels are transient in the blood. It would be wise to work with a functional practitioner who understands this imbalance, knows the particulars of pyrrole disorder, excess copper syndrome, the consequences of copper dumping and can correctly interpret your blood and hair results.
