Blog — Rule Out Iodine Deficiency

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...

By Tracy Tranchitella The role that iodine plays in the thyroid is well established. We need iodine to make thyroid hormones, and the numeric designation in T3 and T4 represents the number of iodine molecules attached to the amino acid tyrosine. In part one of this series on iodine, I examined the versatility of this unique element and its uses throughout history and explored the sources and forms of iodine found in foods and supplements. In part two of this series, I take a closer look at the role that iodine plays in the thyroid and in various extrathyroidal tissues...

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...

As January's Thyroid Awareness Month winds down, now is the time to practice all we've learned about the care and feeding of our master of metabolism. In Part I of our last blog post, we zeroed in on the enemies of a healthy thyroid. In Part II, we will help you fend them off to protect the health of your thyroid gland with the following key action steps. Reverse Estrogen Dominance - An imbalance of high estrogen / low progesterone can suppress activation of thyroid hormones that drive metabolism. Your best defense: If testing detects a problem, consider supplementing with natural (bioidentical) progesterone to re-balance estrogens...
