Heavy metals are a type of environmental toxin that can accumulate in the body and contribute to a wide range of health problems including neurological disorders, kidney damage, and cardiovascular disease. These toxins are found in many sources including food, water, air pollution, and industrial processes. They are toxic because they can interfere with the normal functioning of cells, leading to oxidative stress, inflammation, and damage to DNA and other biomolecules.
The first step in any detox program is to identify the sources of heavy metal exposure and to reduce exposure as much as possible. This may involve changes in diet, lifestyle, and exposures to environmental factors. By reducing exposure to heavy metals, the body is better equipped to handle the elimination of these toxins from the body.
In the upcoming sections of this guidebook, you will come across a toxin exposure questionnaire that can assist you in identifying potential sources of exposure.
Let’s discuss some of these heavy metals that you might be exposed to.
Mercury is a naturally occurring metal that can be found in the environment in various forms, including elemental mercury, inorganic mercury compounds, and organic mercury compounds. Exposure is a public health concern especially for pregnant women, infants, and young children.
One of the most common ways humans are exposed to mercury is through consuming contaminated fish and seafood. Mercury can accumulate in fish and seafood through contaminated water sources. Pregnant women, infants, and young children are particularly vulnerable to the effects of mercury toxicity, as exposure during pregnancy and early childhood can lead to developmental delays, cognitive impairment, and other neurological damage.
Another source of mercury exposure is dental amalgams, which are fillings that contain a mixture of metals, including mercury. While the use of dental amalgams has declined in recent years, they are still used in some dental procedures. It’s important to note that the American Dental Association considers dental amalgams to be safe, but some individuals may choose to have their amalgams removed due to concerns about mercury toxicity.
Industrial sources, such as coal-fired power plants and certain manufacturing processes, are also a significant source of mercury pollution. Mercury can be released into the air and water through these processes, leading to environmental contamination and potential exposure for nearby populations.
To reduce exposure to mercury, it’s important to consume fish and seafood that are low in mercury, such as salmon, sardines, and trout. Pregnant women, infants, and young children should avoid consuming fish that are high in mercury, such as shark, swordfish, and king mackerel.
For individuals with dental amalgams, it may be possible to have them removed and replaced with alternative materials. However, the risks and benefits of dental amalgam removal should be carefully evaluated on a case-by-case basis.
Cadmium is a heavy metal that is widely distributed in the environment and is considered a significant environmental toxin. Exposure to cadmium can occur through various sources, including food, tobacco smoke, and contaminated air and water.
Tobacco smoke is another significant source of cadmium exposure. Cadmium is found in tobacco leaves and can accumulate in the lungs and other organs of individuals who smoke or are exposed to secondhand smoke. Exposure to cadmium through tobacco smoke is associated with an increased risk of lung cancer and other respiratory diseases.
Industrial sources, such as mining and manufacturing operations, can also release cadmium into the environment through air and water pollution. Individuals who live or work near these sources need to be aware of potential cadmium exposure from the soil. This can result in the consumption of contaminated food, particularly grains, leafy vegetables, and root crops. Cadmium can also be found in certain types of seafood where the water has been contaminated, such as mussels and oysters.
Individuals who smoke should quit smoking or avoid exposure to secondhand smoke. It’s also important to be aware of potential sources of cadmium exposure and to take appropriate precautions to reduce exposure.
Aluminum is a naturally occurring metal that is widely used in many everyday products, including food packaging, cookware, and antacids. While aluminum is considered safe for most individuals, high levels of aluminum exposure can be toxic and have been linked to various health concerns.
One of the primary sources of aluminum exposure is through the consumption of processed foods and beverages that are packaged in aluminum cans or containers. Aluminum can also leach into food during cooking or storage in aluminum cookware or foil. While the amount of aluminum that leaches into food is generally considered to be low, frequent exposure to aluminum-containing products can lead to accumulation in the body over time.
Another potential source of aluminum exposure is through the use of certain antacids and other medications that contain aluminum. While these medications are generally considered safe when used as directed, individuals who take these medications frequently or for extended periods of time may be at increased risk of aluminum toxicity.
To reduce exposure to aluminum, it’s important to consume a healthy, balanced diet that is low in processed foods and beverages that are packaged in aluminum. Individuals who cook with aluminum cookware or foil may wish to switch to alternative materials, such as stainless steel or glass. It’s also important to be aware of potential sources of aluminum exposure in medications and to talk to a healthcare professional about alternatives if frequent use is necessary.
Arsenic is a naturally occurring metalloid that is widely distributed in the environment and is considered a significant environmental toxin. Exposure to arsenic can occur through various sources, including food, water, and air.
One of the primary sources of arsenic exposure is through the consumption of contaminated drinking water or food. Arsenic can leach into drinking water from natural sources or through industrial pollution. Arsenic can be found in rice due to various factors, such as the soil it is grown in, the use of contaminated water for irrigation, and certain agricultural practices. Certain types of seafood, such as shellfish, may also contain high levels of arsenic due to environmental contamination.
Lead exposure is a serious public health concern, particularly for children. Even low levels of lead exposure can have long-lasting effects on health, including neurological damage, developmental delays, and an increased risk of cardiovascular disease. Understanding the most common ways humans are exposed to lead is essential for reducing exposure and promoting overall health and wellbeing.
Contaminated drinking water is one of the most common ways humans are exposed to lead. Lead can leach into drinking water from old pipes or plumbing fixtures, particularly in older homes or buildings with lead-based plumbing. To reduce exposure to lead in drinking water, it’s important to use water filtration systems that are certified to remove lead.
Lead-based paint is another common source of lead exposure, particularly in older homes and buildings built before 1978. Lead-based paint was commonly used in homes and buildings before it was banned, and it can still be found on walls, doors, windows, and other surfaces. To reduce exposure to lead-based paint, it’s important to avoid scraping, sanding, or otherwise disturbing lead-based paint.
Soil and dust can also be a source of lead exposure, particularly in areas with high levels of industrial pollution or leaded gasoline use. Children can be exposed to lead by playing in contaminated soil or by breathing in contaminated dust.
Occupational exposure is another potential source of lead exposure, particularly in occupations such as construction work, mining, and battery manufacturing. Workers in these industries may be exposed to lead through inhalation or skin contact with lead-containing materials.

Individuals who rely on canned foods should choose BPA-free cans and look for low-tin options. It’s also important to be aware of potential sources of tin exposure in the workplace and to take appropriate precautions to reduce exposure.
A combination of laboratory testing and clinical evaluation is required to determine the presence and severity of heavy metal toxicity. This may include testing for heavy metals in blood, urine, hair, or other bodily fluids. It’s also important to evaluate other underlying imbalances, such as inflammation, oxidative stress, hormonal imbalances, and gut dysbiosis, which may contribute to heavy metal toxicity.
The specific tests used to evaluate heavy metal toxicity may vary depending on an individual’s health history, symptoms, and risk factors for heavy metal exposure. Some of the most commonly used tests include:
Blood tests can measure the level of heavy metals circulating in the bloodstream. This can provide a snapshot of recent exposure and can help to identify acute toxicity. However, blood tests may not be as effective at detecting chronic exposure or long-term accumulation of heavy metals.
Urine tests can measure the level of heavy metals that are being excreted by the body. This can provide a more comprehensive assessment of heavy metal exposure over time. However, urine tests may not be as effective at detecting some types of heavy metals, such as lead, which can be stored in bones and tissues.
Hair tests can measure the level of heavy metals that have been stored in hair tissue over time. This can provide a more comprehensive assessment of long-term exposure to heavy metals. However, hair tests may not be as effective at detecting recent exposure or acute toxicity.
Completing a detoxification protocol can be a highly effective way to remove these toxins from the body and improve overall health.
The first step in a heavy metal detoxification protocol is always to identify the sources of exposure. Once the sources of exposure have been identified, a targeted detox protocol can be implemented to remove these toxins from the body.
The primary mechanism of heavy metal detoxification is through the use of chelating agents, which bind to the heavy metals and facilitate their excretion from the body. Chelating agents include natural options such as cilantro, chlorella, and spirulina. These work by binding to the heavy metals and transporting them to the kidneys or liver for excretion.
Cilantro, also known as coriander, contains a compound called cilantro oil, which has been shown to bind to heavy metals and promote their excretion through urine and feces. Cilantro oil has a chelating effect, which means it can bind to heavy metals like mercury and lead, making them more water-soluble and easier to eliminate from the body.
Chlorella is a type of green algae that has also been found to be effective at binding to heavy metals, particularly mercury. Chlorella has a high concentration of chlorophyll, which has been shown to bind to heavy metals in the digestive tract and promote their excretion. In addition, chlorella contains a unique compound called Chlorella Growth Factor (CGF), which has been found to increase the elimination of heavy metals from the body.
Spirulina is another type of algae that has been found to be effective at binding to heavy metals, particularly arsenic and cadmium. Spirulina contains high amounts of phycocyanin, a blue pigment that has been found to have chelating properties. Phycocyanin has been shown to bind to heavy metals and promote their excretion from the body.
They are chelating agents that can be used as medications for heavy metals.
DMSA is commonly used for the removal of lead, arsenic, and mercury from the body. It is a water-soluble compound that is able to bind to metals in the blood and tissues, allowing for their elimination through the kidneys. DMSA can also cross the blood-brain barrier, making it effective in removing heavy metals from the brain and nervous system.
EDTA is a synthetic amino acid that also binds to heavy metals in the body, but is particularly effective at removing toxic metals such as lead, cadmium, and mercury. It works by chelating the metal ions and forming stable complexes that are excreted through urine.
Both DMSA and EDTA have potential side effects, including nausea, vomiting, and diarrhea. It is important to work with a healthcare provider to determine if chelation therapy is necessary and to monitor for any adverse effects.
