Arsenic (As) – Elevated

​

What it means?

Arsenic (As) is a naturally occurring element that, in very low amounts, may play a minor physiological role, but it is well known for its toxicity at higher levels. Hair analysis is considered an excellent indicator of arsenic exposure and overall body burden.

​

Health connections:

​

• Toxicity risks: Elevated arsenic is associated with malaise, digestive upset, muscle pain, and skin changes. Long-term exposure is linked to increased cancer risk.

• Organic vs. inorganic arsenic:

  • Organic arsenic (commonly found in seafood) is rapidly excreted and usually requires constant exposure to remain elevated.

  • Inorganic arsenic (from environmental or industrial sources) accumulates in tissues and is far more toxic. It ranks second among heavy metals as a cause of death.

• Mineral interactions: Arsenic is a strong biological antagonist of selenium, meaning it can interfere with selenium’s protective functions.

​

Common sources / Notes:

​

• Insecticides and pesticides

• Industrial exposures, such as electroplating or electronics manufacturing

• Air pollution and smog

• Contaminated food or water (particularly groundwater in certain regions)

• Rarely, external contamination of hair in an acidic environment

​

Symptoms that may be linked to arsenic excess:

​

• Fatigue, malaise

• Digestive problems (nausea, abdominal pain, diarrhea)

• Muscle weakness or pain

• Skin changes (irritation, discoloration, lesions)

• Increased long-term cancer risk

​

Reassurance:

When arsenic (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.
