What is iodine? 

Iodine is a vital chemical element necessary for the production of thyroid hormones, which play a crucial role in regulating metabolism, growth, and development. It is primarily obtained through the diet, found in foods like seafood, seaweed, and iodised salt.

In addition to its importance in thyroid function, iodine has various applications. It is widely used as a disinfectant and antiseptic agent due to its ability to kill bacteria, viruses, and fungi. Iodine compounds are also utilised in the production of dyes, pharmaceuticals, and organic synthesis.

In the medical field, iodine-based contrast agents are commonly employed for diagnostic imaging, enabling clearer visualisation of internal structures during X-rays, CT scans, and other medical procedures.

Insufficient iodine intake can result in iodine deficiency disorders, including goitre and hypothyroidism. To combat this, many countries have implemented iodised salt programs to ensure adequate iodine consumption and prevent related health complications.
