Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — iodine and thyroid health

Iodine deficiency is a significant and underappreciated global health problem, with urinary iodine levels in many Western populations having fallen substantially over recent decades. As an essential component of thyroid hormones, iodine deficiency impairs thyroid function, promotes goitre, and has wide-ranging consequences for metabolism, cognitive development, breast health, and reproductive health. Women of childbearing age are particularly vulnerable. This article explains the causes and consequences of iodine deficiency, who is most at risk, and how at-home dried urine testing using ICP-MS analysis can accurately confirm your iodine status.

Environmental pollutants are in the food we eat, the air we breathe and the water we drink — and in excess, they can profoundly disrupt thyroid hormone synthesis and action. This article explains how iodine and selenium deficiencies develop, how antagonists like bromine, arsenic and mercury exacerbate thyroid dysfunction, and why urine testing for these five elements can reveal the hidden environmental drivers of thyroid symptoms that standard blood tests miss.
