Heavy Metal Toxicity and the Thyroid Gland

Heavy metals are found in the environment (air, water, food, soil). Over time they place an extreme toxic burden on the body.  Heavy metals enter the body by ingestion, inhalation, or absorption through the skin or mucous membranes.

The thyroid is very sensitive to heavy metals. Research has shown that heavy metals can damage the thyroid.

This is a list of some of the heavy metals that have been shown to have a negative effect on the thyroid gland.


Found in cosmetics, pesticides, fish, vaccines, dental fillings. If you live near a coal burning plant you are exposed to 70,000 pounds of mercury each year that is pumped into the air. There is a strong link between mercury and autoimmune diseases.


Found in rocket fuel and fertilizers. Because of fertilizer run off, it’s in the water supply. Even in very low levels percolate causes a decrease in thyroid function


Found in fertilizer and food. Processed foods like hot dogs and bacon are preserved with nitrates. Nitrate has been linked to cancer.

Using a food based purification program every 6 months to a year can help rid your body of harmful toxins such as heavy metals.

Besides for heavy metals, there are several other factors that affect thyroid function. They can be environmental like endocrine disruptors such as xenoestrogens or radiation or stress.
