Iodine's Role in Thyroid Health - Verywell Health
2024年11月11日 · Iodine is an element that's required for the thyroid gland to produce thyroid hormones. Since the body does not produce iodine on its own, it needs to come from dietary sources—and striking the right balance is key.
Iodine and thyroid function - PMC - PubMed Central (PMC)
Iodide is known to control thyroid function. Its main effects are to decrease the response of the thyroid to thyrotropin (TSH); to acutely inhibit its own oxidation; to reduce its trapping after a delay; and, at high concentrations, to inhibit thyroid hormone secretion 12).
Excess iodine intake: sources, assessment, and effects on thyroid ...
Our review describes the association between excess iodine intake and thyroid function. We outline potential sources of excess iodine intake and the physiological responses and consequences of excess iodine intakes. We provide guidance on choice of biomarkers to assess iodine intake, with an emphasis on the UIC and thyroglobulin.

Learn about the role iodine plays in the functioning of a healthy thyroid and whether people with thyroid conditions require it or not
Iodine Deficiency and Iodine Prophylaxis: An Overview and Update
The thyroid gland requires iodine to synthesize thyroid hormones, and iodine deficiency results in the inadequate production of thyroxine and related thyroid, metabolic, developmental, and reproductive disorders. Iodine requirements are higher in infants, children, and during pregnancy and lactation than in adult men and non-pregnant women.
Iodine, Thyroglobulin and Thyroid Gland - PMC - PubMed …
Iodine is essential in the biosynthesis of thyroid hormones that affect metabolic processes in the organism from the prenatal state to the elderly. The immediate indicator of iodine intake is the concentration of iodine in urine, but the indicator of iodine intake in the longer term of several months is thyroglobulin (Tg).
Iodine: Its Role in Thyroid Hormone Biosynthesis and Beyond
2021年12月14日 · The main biological function of iodine concerns its role in the biosynthesis of thyroid hormones (THs) by the thyroid gland. In addition, however, further biological roles of iodine have emerged. Precisely, due to its significant action as scavenger of reactive oxygen species (ROS), iodine is thought to represent one of the oldest antioxidants ...

2020年9月30日 · Iodine is essential in the biosynthesis of thyroid hormones that affect metabolic processes in the organism from the prenatal state to the elderly. The immediate indicator of iodine intake is the concentration of iodine in urine, but the indicator of iodine intake in the longer term of several month …
Iodine deficiency and thyroid disorders - PubMed
Iodine deficiency early in life impairs cognition and growth, but iodine status is also a key determinant of thyroid disorders in adults. Severe iodine deficiency causes goitre and hypothyroidism because, despite an increase in thyroid activity to maximise iodine uptake and recycling in this setting, iodine concentrations are still …
Iodine and Thyroid Hormone Synthesis, Metabolism, and Action
2017年1月1日 · Iodine is a crucial micronutrient for thyroid hormone synthesis and the only source is dietary. Iodide (I −) is absorbed in the stomach and small intestine, and is concentrated from the blood stream into the thyroid follicular cell through the action of …
