Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — heavy metals and kidney health

Selenium is an essential trace element with a critical role in immune function, antioxidant defence, and thyroid health. Research links selenium deficiency to increased viral replication, more severe infection outcomes, and a higher likelihood of viral mutation into new strains. Heavy metal exposure from mercury and arsenic can further deplete selenium, compounding the risk. This article explains the science behind selenium’s role in viral protection, the geographical link between selenium-deficient soils and emerging infectious diseases, and how at-home ICP-MS testing can confirm whether your selenium levels are adequate.

That shiny bracelet or pair of earrings may look harmless — but it could contain cadmium, a toxic heavy metal ranked the 7th most significant threat to human health. With a half-life of 10–30 years in the body and no safe level of exposure, understanding where cadmium comes from and testing your levels is a smart step for long-term health.

Crystal glassware looks beautiful, but it may be silently adding lead to your wine.
