Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — selenium deficiency

Heavy metals and essential elements testing helps identify toxic exposures and nutrient imbalances that can impact hormones, metabolism, immune function, and neurological health. Using convenient dried urine and dried blood spot methods, this testing provides a comprehensive view of elemental status, enabling more personalized strategies for detoxification, nutritional support, and long-term wellness.

Toxic heavy metals and essential nutrient imbalances can silently undermine your health. Discover how at-home elements testing using dried urine and blood spot samples can uncover what standard tests miss.

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.

Brazil nuts are widely used as a natural selenium supplement, but the selenium content in each nut varies enormously depending on soil conditions, region, and even individual trees. While selenium is essential for thyroid function, antioxidant defence, and overall health, both deficiency and excess carry serious risks. This article explains why Brazil nuts are so variable as a selenium source, what the safe daily intake looks like, and why testing your selenium levels is the most reliable way to know whether your intake is adequate, insufficient, or dangerously high.
