If you often feel tired, struggle with weight changes, or have thyroid concerns, it might be time to check your iodine levels with a simple home test.

 

By Tracy Tranchitella, ZRT Laboratory. At the most fundamental level, the beneficial actions of iodine derive from its ability to function as both an antioxidant and an oxidant. These basic qualities also support its effects as an antimicrobial, anti-proliferative and anti-cancer agent. How iodine functions within the human body is determined by its form, the tissue in which it resides and the overall physiological context. Iodine’s role as an antioxidant is determined by its ability to donate electrons and quench free radicals thereby reducing tissue damage and oxidative stress that may lead to chronic disease. As an oxidant, iodine can...

Most people associate iodine exclusively with thyroid health — but this essential mineral plays a far broader role in the body. From breast tissue and ovarian function to fetal brain development and endometrial health, iodine is active in virtually every organ system. Deficiency is more widespread than commonly recognised, and standard thyroid blood tests cannot reliably detect it. This guide explores the extrathyroidal roles of iodine, the difference between iodide and molecular iodine, the controversy around dosing, and why testing urinary iodine is the most accurate way to assess your status.

By Tracy Tranchitella The use of iodine dates back to 4th century China where seaweed and burnt sea sponge were effectively used to treat goiter. It was not until 1811 that iodine was isolated as a specific element that exhibited properties similar to the other halogens of bromine, chlorine, and fluorine. In 1829, Jean Guillaume Auguste Lugol, MD, introduced potassium iodide as an effective treatment for the effects of tuberculosis, and John Murray, MD, used iodine to treat croup, asthma, consumption, and other respiratory diseases [1]. Tincture of iodine has been a staple in every first aid kit for the...

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.
