What is Mercury?

Mercury is a naturally occurring heavy metal that can be toxic to humans, especially in high concentrations. It can enter the body through contaminated seafood, environmental exposure, dental amalgams, or occupational hazards. Blood mercury levels reflect recent exposure and are used to evaluate the risk of mercury poisoning.

What does it assess?

Mercury levels in the blood are assessed to detect toxic exposure. Elevated levels may indicate environmental, dietary, or occupational contamination and help evaluate symptoms such as tremors, fatigue, cognitive decline, or kidney dysfunction.

How do I optimize my Mercury levels?

Avoid high-mercury fish like swordfish, king mackerel, and shark. Prioritize low-mercury seafood like salmon and sardines. Filter drinking water if you're in an area with known heavy metal contamination. Consider chelation therapy only under medical supervision if toxicity is confirmed. Pregnant individuals should be especially cautious due to fetal neurodevelopmental risks.

What does a good and bad Mercury level look like?

Normal blood mercury levels are typically less than 5 µg/L. Levels above this may warrant further investigation and lifestyle changes. Significantly elevated values (≥15 µg/L) may indicate mercury poisoning and require medical intervention.
