Iodine

Iodine is a naturally occurring mineral essential for human health. It is found in seawater, soil, and certain foods, particularly seafood and dairy products. In food production, it can be added as a nutrient, often in the form of potassium iodide or iodate.

Iodine is primarily added to foods as a nutrient to help prevent deficiency. It is commonly found in products fortified with vitamins and minerals, such as some multivitamin supplements, infant formulas, and certain dairy alternatives like soy-based drinks. Its presence ensures consumers can meet their dietary requirements for this essential mineral.

Iodine is an essential nutrient, vital for the production of thyroid hormones which regulate metabolism. The UK government recommends adequate iodine intake to support thyroid function. The Food Standards Agency (FSA) and Food Standards Scotland (FSS) monitor nutrient levels in food. While iodine is crucial, excessive intake can also have health implications, though this is rare from food sources alone.
