lodised salt (also spelled iodized salt) is regular table salt fortified with iodine, a trace mineral essential for human health. The body cannot produce iodine on its own, so it must come from the diet. Universal salt iodization has been one of the most successful and cost-effective public health interventions worldwide, recommended by the World Health Organization (WHO) to prevent iodine deficiency disorders (IDD).
Prevents lodine Deficiency Disorders (IDD) and Goiter lodine deficiency is a leading cause of goiter (enlarged thyroid gland) and other thyroid problems. Regular use of iodised salt significantly reduces goitre rates and helps maintain healthy thyroid size and function.
Supports Thyroid Hormone Production lodine is a critical building block for thyroid hormones (thyroxine/T4 and triiodothyronine/T3). These hormones regulate metabolism, heart rate, body temperature, growth, and energy levels. Adequate iodine keeps the thyroid functioning normally and prevents hypothyroidism. Promotes Healthy Brain and Cognitive Development lodine is vital for fetal and early childhood brain development. Deficiency during pregnancy can lead to irreversible cognitive impairments, lower IQ, developmental delays, and in severe cases, cretinism (severe physical and mental retardation). Using iodised salt helps ensure better psychomotor and cognitive outcomes in children.
Crucial for a Healthy Pregnancy
Pregnant and lactating women have higher iodine needs. Sufficient intake reduces risks of miscarriage, stillbirth, congenital abnormalities, and supports proper bone and brain development in the baby. It also helps prevent maternal hypothyroidism, which can worsen during pregnancy.Helps Maintain Overall Health and MetabolismBy supporting thyroid function, iodised salt contributes to healthy metabolism, which can indirectly help with weight management. It also supports energy levels, immune function, and general well-being.
Easy, Inexpensive, and Effective Supplementation Salt is consumed daily by almost everyone in consistent amounts, making iodisation a practical way to deliver iodine to entire populations without requiring major dietary changes.

lodised salt starts as regular sodium chloride, obtained either by evaporating seawater or mining underground rock salt deposits. During processing, manufacturers add a small amount of iodine compounds-usually potassium iodate (more stable in humid conditions) or potassium iodide. The salt is then refined, sometimes with anti-caking agents, and packaged to protect the iodine from light and moisture.
Other Natural Sources of lodine while iodised salt is the most reliable everyday source for many people, iodine is also naturally present in Seafood (seaweed like kelp and nori, fish such as cod and tuna, shellfish). Dairy products and eggs (often due to iodine in animal feed). Some fruits and vegetables grown in iodine-rich soil. However, natural levels vary widely depending on soil and water content, so iodised salt remains the most consistent option in many regions.
Switching to iodised salt is one of the simplest ways to protect thyroid health, support brain development in children, and safeguard maternal and fetal health. It has dramatically reduced preventable cognitive impairments and thyroid disorders globally. For most people, using iodised salt in everyday cooking is a safe, effective, and low-cost habit with significant long-term benefits.
