Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — heavy metals testing UK

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.

A growing body of research suggests that mitochondrial dysfunction may lie at the root of many treatment-resistant mental health conditions — including depression, anxiety, bipolar disorder, OCD and even dementia. In this clinical overview, Dr. Peter Bongiorno explains why neurons are particularly vulnerable to mitochondrial damage, how stress, heavy metals and hormonal imbalances compound the problem, and what a comprehensive 5-step repair plan looks like in practice.

Learn why the biological sample used for element testing — urine, whole blood, serum, hair, or nails — can dramatically change how toxic and essential mineral results are interpreted. Discover how different sample types reveal recent intake, long-term exposure, body burden, deficiency, or chronic toxicity for elements like mercury, lead, cadmium, arsenic, selenium, zinc, copper, iodine, and magnesium, and why choosing the correct testing method is critical for clinically meaningful results.
