Role Of Iodine In The Thyroid

18 October, 2025

Introduction

The Role Of Iodine In The Thyroid is essential for hormone production and overall metabolic health. Its supports the creation of thyroid hormones (T3 and T4), which control metabolism, growth, energy production, and brain development. When the diet lacks sufficient iodine, the thyroid gland enlarges and causes goiter or hypothyroidism. Maintaining the right iodine level keeps thyroid functions balanced and supports overall wellness.

Role in Thyroid Function

Iodine Absorption:
Iodine is absorbed from food through the digestive system into the bloodstream.
Thyroid Uptake:
The thyroid gland actively takes up iodine from the blood using a special transport system called the sodium–iodide symporter (NIS).
Hormone Production:
Inside the thyroid, iodine binds with the amino acid tyrosine to form T3 (Triiodothyronine) and T4 (Thyroxine).
Regulation by TSH:
The pituitary gland releases TSH (Thyroid-Stimulating Hormone), which tells the thyroid how much iodine and hormone to use and produce.

Effects

Goiter: The thyroid gland becomes enlarged, swelling appears in the neck.

Hypothyroidism: Fatigue, weight gain, hair loss, and slow metabolism are seen.

Problems during pregnancy: Iodine deficiency in the mother affects the child’s brain development.

Delayed mental development: Children may have mental development deficits and educational problems.

The body’s immune system decreases.
