Iodine, commonly referred to as iodide, is a mineral found in the soil and water of the oceans. It is typically present in a variety of meals made from plants and saltwater, with iodized salt being the most accessible source. Iodine is extremely important for human health since it helps to maintain foetal development and regulate hormones. A healthcare practitioner may advise supplementing in cases of low iodine levels, stressing the significance of speaking with a physician before taking iodine supplements to guarantee proper and secure absorption of this crucial mineral.



Iodine is regarded as a mineral that our bodies must have. It’s crucial throughout pregnancy and being exposed to it while a baby is still inside the womb may even help to prevent some illnesses later in life. Some of its health benefits are as follows:

  • Thyroid Health: The thyroid gland, which controls the production of hormones, depends on iodine to function properly. Thyroid hormones in turn regulate important functions like metabolism and heart health. Iodine is necessary for the thyroid gland to synthesise these hormones. Hypothyroidism, a condition marked by an underactive thyroid, can result from an iodine deficit. Although iodine insufficiency is rare in nations with iodine-rich diets like the United States, it is crucial for thyroid health to maintain enough iodine consumption from sources such dairy products, fortified meals, saltwater fish, and iodized salt. It’s important to remember that excessive iodine intake, usually via supplements, can harm the thyroid and should be avoided unless under medical supervision.
  • Reducing the risk of Goitres: Iodine deficiency is one cause of goitres, which are enlargements of the thyroid glands. Iodine-induced goitres can still happen even if they are less frequent in areas with adequate dietary iodine. Thyroid gland enlargement can also be caused by benign thyroid nodules. The development of goitres brought on by an iodine deficit can frequently be cured by ensuring an adequate intake of iodine-rich meals or supplements. However, the underlying cause of goitres must be addressed, which may necessitate medical testing.
  • Managing overacting thyroid Gland: Health care experts may suggest radioactive iodine, a specialised form of iodine, in situations of hyperthyroidism, an overactive thyroid gland. By removing additional thyroid cells, this oral therapy seeks to lower excessive thyroid hormone production. It is often considered when other treatments, such as anti-thyroid medications, have failed. The use of radioactive iodine does, however, carry the danger of unintentionally reducing hormone production, which could result in hypothyroidism. Individuals should never self-administer iodine supplements to treat hyperthyroidism without a doctor’s supervision since radioactive iodine used for medical purposes varies from iodine supplements.

In conclusion, iodine’s importance as a necessary mineral in preserving general health is highlighted by its involvement in thyroid health, goitre prevention, and the treatment of thyroid problems. Even while iodine insufficiency is less frequent in areas with access to iodine-rich foods, maintaining a balance in iodine intake is essential to ensuring adequate thyroid function without running the risk of overdosing on iodine. For advice on iodine-related health issues, individuals must speak with a healthcare expert.


The National Institutes of Health (NIH) recommends iodine intake to promote healthy thyroid function and prevent iodine insufficiency. Depending on age and stage of life, a different amount of iodine is advised daily. Up until the age of six months, newborns must receive 110 mcg, and between the ages of seven and twelve months, they must receive 130 mcg. Children should strive for a daily dose of 90 mcg between the ages of 1 and 8, and those between the ages of 9 and 13 should raise their consumption to 120 mcg.

The suggested daily dosage for adults and teenagers, including those 14 years of age and older, is 150 mcg. The suggested dosage for pregnant moms is 220 mcg throughout pregnancy, when the need for iodine is increased due to foetal growth. It is recommended that nursing mothers take 290 mcg of iodine daily to support both their health and the needs of their nursing infants. Nursing mothers continue to have elevated iodine consumption.

It’s crucial to remember that these suggestions are intended to prevent iodine shortage and advance general wellness. Actual iodine needs might change depending on a person’s lifestyle, diet, environment, and medical conditions. Additionally, while getting the necessary daily amount is important, it’s as important to avoid getting too much iodine, which can have negative consequences on your health. Iodine consumption can be personalised with advice from a healthcare practitioner, ensuring that it fits with each person’s needs and requirements.


Iodine is an essential mineral that, when consumed, has a significant impact on the thyroid gland, a significant endocrine organ positioned in the neck. Thyroxine (T4) and triiodothyronine (T3) are thyroid hormones that are produced by the thyroid gland and are crucial for controlling metabolism, energy production, and a number of physiological processes. These thyroid hormones include a significant amount of iodine in their composition. Iodine is actively taken up by thyroid follicular cells from the circulation using a specialised transporter called the sodium-iodide symporter (NIS).

Iodine atoms are added to the tyrosine residues of thyroglobulin, a protein made by the thyroid gland, during this process, which is crucial for the synthesis of thyroid hormones. The thyroid gland then undergoes further enzymatic processes that result in the production of T4 and T3, which are then released into the bloodstream to have systemic effects on numerous tissues and organs and maintain metabolic balance and general health.


Iodine not only aids in the generation of thyroid hormones but also has antibacterial qualities that support dental health and prevent bacterial overgrowth. It is frequently used as an antiseptic agent in topical treatments for wound disinfection or mouthwashes with an iodine basis. Iodine also aids in the growth of the foetus during pregnancy since it is necessary for the synthesis of thyroid hormones in the growing foetus. For the baby’s brain and nervous system to develop properly, the mother must consume enough iodine. Iodine is a vital mineral in the human body, with its actions having an impact on a variety of physiological functions, including thyroid function, antimicrobial activity, and prenatal health.
