Mercury (Hg) – Elevated

​

What it means?

Mercury (Hg) is a toxic heavy metal with no beneficial role in human health. Hair analysis is considered one of the most accurate ways to reflect mercury burden, since mercury is excreted through hair as part of the body’s detoxification process. Sometimes an elevated hair mercury level reflects active detoxification rather than ongoing toxicity. 

“However, since the body tends to excrete mercury when levels are elevated, its presence in hair indicates a toxic burden and the need to take appropriate steps to support detoxification.”

 

Health connections:

​

• Toxicity risks: Mercury is well documented to affect the nervous system, immune system, and cardiovascular health.

• Individual sensitivity: People vary widely in their sensitivity to mercury. Even low exposures can interfere with selenium’s protective functions.

• Potential effects: Elevated mercury has been associated with hyperactivity, mood and emotional changes, neuromuscular disorders, loss of appetite, headaches, and irritability.

• Cardiovascular link: Research has shown that for every 1 part per million increase in hair mercury, there may be up to a 9% increase in risk of acute myocardial infarction (heart attack).

 

Common sources / Notes:

​

• Dental: Mercury amalgam fillings often raise hair mercury for 6 months to over a year following placement.

• Dietary: Seafood (especially large predatory fish such as tuna, swordfish, and shark) and contaminated water are common sources.

• Medical / cosmetic: Some hemorrhoid preparations and skin-lightening creams contain mercury.

 

Symptoms that may be linked to mercury excess:

​

• Neurological: hyperactivity, tremors, mental or emotional changes

• Musculoskeletal: neuromuscular weakness or pain

• Digestive: loss of appetite, nausea

• General: headaches, irritability, fatigue

​

Reassurance:

When mercury (or other heavy metals) are low or undetectable, this is normal and not a health concern. There is no need for supplementation, treatment, or additional reporting in those cases.
