The importance of iodine.

Iodine is a trace element that is naturally present in many foods. It is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroid hormones are extremely important as they regulate important physiological and biochemical functions, such as protein synthesis and enzymatic activity, and are vitally important and determinant in metabolic activity^1,2. They are also necessary for the health of bones and the development of the nervous system¹.

Thyroid function is primarily regulated by the thyroid-stimulating hormone (TSH), which is secreted by the pituitary gland. The secretion of TSH increases the absorption of iodine by the thyroid and stimulates the synthesis and release of T3 and T4. Iodine deficiency causes TSH levels to remain high and increases the likelihood of producing goiter, a pathology that enlarges the size of the thyroid and reduces the ability to assimilate iodine, greatly affecting thyroid function and health. In addition, iodine also plays a fundamental role in the immune system².

Iodine absorption.

Iodine is quickly absorbed in the stomach and duodenum, once in the circulation the thyroid concentrates it in appropriate amounts for the synthesis of thyroid hormones^2,3. The body's iodine reserves are 15-20 mg and 80% is in the thyroid⁴.

Recommended intake^7,8:

Iodine deficiencies.

In the case of adults, the lack of this mineral in the diet can promote the development of goiter or hypothyroidism³. If iodine intake is less than 10-20 µg/day, hypothyroidism occurs¹, Iodine deficiency causes growth and development problems, being the leading cause of intellectual disability⁹. During pregnancy and early childhood, iodine deficiency can cause irreversible problems⁶.

Functions of iodine:

• Essential for the production of thyroid hormones.
• Essential for growth.
• It contributes to using fat as a source of energy and improves mental agility¹⁰.
• Intervenes in neuromuscular processes^3,4.
• It participates in the proper cellular functioning and is necessary for the metabolism of carbohydrates^3,4.
• Essential for the health of hair, teeth and nails.

Interactions: treatments for thyroid and diuretics, consult with your doctor before consuming it.
