Cadmium (Cd) – Elevated

​

What it means?

Cadmium (Cd) is a toxic heavy metal with no known biological function in the human body. Hair analysis is considered a reliable way to detect cadmium exposure, since it accumulates in tissues over time.

​

Health connections:

​

• Cardiovascular: Mildly elevated cadmium has been linked with essential hypertension, while levels above 3 ppm have been associated with low blood pressure (hypotension).

• Organs affected: Cadmium tends to concentrate in the kidneys (especially the renal cortex) and is also found in arterial walls, lungs, bones, and reproductive organs.

• Metabolic impact: It interferes with many enzyme systems, weakening detoxification and overall metabolic balance.

• Mineral interaction: Zinc, calcium, and selenium can reduce cadmium absorption, offering some natural protection.

​

Common sources / Notes:

​

• Dietary: Cadmium occurs naturally in food. Levels can range from very low (0.04 ppm in some fruits) to higher levels in seafood such as oysters and anchovies (3–5 ppm).

• Lifestyle: Cigarette smoking significantly increases cadmium absorption and is one of the most common sources of elevated cadmium.

• Environmental: Industrial emissions, contaminated soils, and fertilizers may contribute to exposure.

​

Symptoms that may be linked to cadmium excess:

​

• Kidney stress or dysfunction

• Respiratory problems (cough, lung irritation)

• Bone pain or weakness

• Vascular issues (hypertension or hypotension, depending on levels)

• Fatigue, infertility, or hormonal disturbances

​

Reassurance:

When cadmium (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.

Even mild elevations suggest a toxic burden and warrant detoxification steps
