Iodide: Importance for Thyroid Hormone Synthesis and Body Function – Sources, Deficiency and Excess Effects

Iodide

I⁻

Iodide is a negatively charged ion that contains one iodine atom and has a charge of -1. It is an important nutrient for the body and is essential for the synthesis of thyroid hormones. Iodide can be found abundantly in seawater and soil, but can also be consumed through iodized salt, seafood, and dairy products.

In the body, iodide is actively transported into the thyroid gland where it is converted into iodine and incorporated into thyroid hormones. These hormones are responsible for regulating the body’s metabolic rate, growth, and development. A deficiency in iodide can lead to hypothyroidism, which is a condition characterized by an underactive thyroid gland and symptoms such as fatigue, weight gain, and depression.

Excessive iodide intake can also have negative effects on the body, causing hyperthyroidism and even thyroid gland destruction in severe cases. It is important to maintain a balanced intake of iodide in the diet and to consult a healthcare professional for personalized recommendations.
