Can your body get rid of heavy metals on its own?

Heavy metal toxicity is a major health concern. Heavy metals like lead, mercury, arsenic, cadmium, and aluminum can accumulate in the body over time and cause various health problems. The main question is – can your body get rid of these heavy metals naturally, or do you need to take special supplements or undergo medical procedures to remove them?

How Heavy Metals Get Into Your Body

There are many ways heavy metals can enter your body:

  • Eating contaminated fish and seafood
  • Drinking contaminated water
  • Exposure to lead-based paints
  • Living near industrial sites that release heavy metals into the environment
  • Eating produce grown in contaminated soil
  • Breathing polluted air
  • Working in occupations with heavy metal exposure (e.g. mining, welding, manufacturing)
  • Using certain cookware, jewelry, toys, and other consumer products containing heavy metals
  • Taking contaminated supplements or traditional medicines

Once in your body, heavy metals build up over time since they are not easily metabolized or excreted. They accumulate in organs like the liver, kidneys, bones, and brain. Toxic load increases over months and years of exposure.

Do Heavy Metals Naturally Leave the Body?

The body does have some natural detoxification processes that can help eliminate heavy metals, but they are slow and not fully efficient at removing high toxic loads. Here are some of the ways the body tries to get rid of heavy metals on its own:

1. Liver Detoxification

The liver produces bile and enzymes that help convert heavy metals like mercury into less toxic compounds. These can then be eliminated via feces and urine. However, if there is high exposure, the liver may get overwhelmed.

2. Kidney Filtration

The kidneys filter the blood and excrete waste products in urine. Toxic metals like cadmium and arsenic are filtered out and excreted through urine. But kidneys can get damaged by high heavy metal exposure.

3. Sweating

Sweat can eliminate small amounts of toxic metals like arsenic, cadmium, lead, and mercury over time. However, sweating alone cannot remove high heavy metal loads.

4. Hair and Nails

Traces of heavy metals are excreted through hair and nails as they grow out. But this elimination is extremely slow and small.

5. Feces

Some heavy metals eliminated in bile get excreted through stools. But again, regular bowel movements cannot remove high toxic accumulation.

While the body does try to get rid of heavy metals naturally, it cannot fully eliminate high levels toxic body burden. The natural detoxification systems can get overwhelmed and damaged by large, ongoing exposure to heavy metals over months and years.

Factors that Impact Natural Heavy Metal Detoxification

Several factors influence how well your body can naturally detoxify and excrete heavy metals, including:


Younger people tend to detoxify better than older adults. Natural heavy metal detoxification reduces with age as the organs become less efficient.


Genetic defects in detoxification pathways can reduce natural heavy metal excretion. People with certain genetic polymorphisms in genes that control metal transport and metabolism accumulate higher levels.

Nutritional Deficiencies:

Mineral deficiencies like low zinc, selenium, iron reduce the activity of metal detoxification enzymes and proteins. Toxic metal burden increases.

Gut Health:

Poor gut health with inflammation, leaky gut, dysbiosis allows greater absorption of ingested heavy metals into the body.

Overall Health:

Chronic illnesses like diabetes and kidney disease hamper the body’s natural ability to detoxify and eliminate heavy metals.

Bioaccumulation of Heavy Metals

Since the body’s natural detoxification processes work slowly and are incomplete, heavy metals tend to bioaccumulate in the body over time with continued exposure. Bioaccumulation means the concentration of toxins increases in the body faster than it can be removed.

Heavy metals get stored in various tissues – especially bones, liver, kidneys. Toxic metals keep accumulating as exposure continues, eventually reaching dangerously high levels.

Some heavy metals have extremely long half-lives in the body. For example:

  • The half-life of cadmium ranges from 10 to 33 years.
  • Lead has a half-life ranging from 2 to over 10 years in bones.
  • Mercury has a half-life of 2 months to several years depending on the form of mercury.

This means even if exposure stops, it can take many years to clear 50% of the accumulated heavy metals naturally. The remaining metals keep causing toxicity.

Health Effects of Heavy Metal Accumulation

Chronic heavy metal toxicity can have serious effects on health over time. Some potential effects include:

Heavy Metal Health Effects
Lead Cognitive decline, neurological disorders, kidney damage, hypertension, fertility issues
Mercury Neurological damage, memory loss, kidney damage, autoimmune conditions
Cadmium Kidney disease, osteoporosis, cardiovascular disease, cancer
Arsenic Cancer, skin lesions, cardiovascular disease, diabetes
Aluminum Alzheimer’s disease, impaired neurological development

Since many heavy metals damage organs involved in detoxification, their accumulation eventually hampers the body’s natural ability to excrete them. This vicious cycle worsens the toxicity.

Chelation Therapy for Heavy Metal Detox

Since the body cannot fully eliminate heavy metals on its own, alternative treatment is needed to “chelate” or bind to the metals and facilitate their removal. This is known as chelation therapy.

Chelation therapy involves taking certain substances orally or through IV that bind to heavy metals in the body. This allows the toxins to be flushed out through urine and stool. Chelating agents include:

  • EDTA (ethylenediaminetetraacetic acid)
  • DMPS (dimercaptopropane sulfonate)
  • DMSA (meso-dimercaptosuccinic acid)
  • ALA (alpha lipoic acid)
  • Cilantro
  • Garlic
  • Chlorella

Chelation therapy should always be done under medical guidance as it can have side effects. It may need to be done over months to years depending on the extent of metal accumulation in the body.

Natural Remedies to Aid Heavy Metal Detox

While chelation is the strongest medical treatment, some natural remedies can also aid your body’s detoxification process:

1. Take Metal-Binding Supplements

Some supplements help bind and excrete toxic heavy metals:

  • Chlorella – This algae has chlorophyll and proteins that bind to mercury, cadmium, and lead.
  • Cilantro – It contains polyphenols that chelate lead, aluminum, and mercury.
  • Garlic – Sulfur compounds in garlic bind to heavy metals.
  • Milk thistle – It boosts glutathione levels which is needed for metal detox.

2. Eat Fiber and Probiotics

A high fiber diet with prebiotic foods promotes elimination of metals through feces. Probiotics improve gut environment and prevent reabsorption of toxins.

3. Consume More antioxidants

Antioxidants like vitamin C, vitamin E, selenium, lutein help protect cells from heavy metal damage. Fruits, vegetables and green tea are high in antioxidants.

4. Exercise and Sweat

Regular exercise helps stimulate circulation and sweat release. This facilitates excretion of toxins.

5. Get Good Nutrition

Eating less processed foods and more whole foods ensures adequate intake of minerals needed for detox enzymes and proteins to function.

When is Medical Heavy Metal Detox Needed?

While natural detox remedies can help, they have limited benefits in high toxic loads. Medical chelation therapy is recommended in situations like:

  • Known high exposure to heavy metal contamination (workplace, environment)
  • Symptoms of chronic toxicity like impaired cognition, neurological issues
  • Bioaccumulation indicated by hair/urine/blood tests
  • Pre-existing kidney, liver, and metabolic issues

Chelation therapy along with natural detox methods can help reverse the long-term buildup of heavy metals. Always consult a doctor before starting any heavy metal detox protocol.


In summary, the body does have some natural capacity to excrete small amounts of heavy metals through urine, stool, sweat, hair, and nails. However, this natural detoxification is slow, incomplete, and gets impaired at high toxic loads. When exposure is ongoing, heavy metals keep bioaccumulating to dangerous levels and can cause serious health disorders.

Natural heavy metal detox remedies like metal-binding supplements, antioxidants, exercise, and probiotics can provide some benefits but are insufficient in high toxicity. Medical chelation therapy is more effective at removing body burden in such cases. A combination of natural methods and chelation guided by a practitioner is ideal for comprehensive heavy metal detox. The first step is getting a proper diagnostic assessment.
