Source ? Iodine is mainly present in iodised sea salt. It is however essential to seek out other iodine-rich sources, as new recommendations suggest limiting use of table salt in order to reduce the risk of excessively high blood pressure. It can therefore be found in crustaceans and other seafood products such as marine fish (cod, sardines and mackerel), algae, oysters and shellfish, and also in cod liver oil, meat, eggs, dairy products and certain cereals.
What does it do ? Iodine contributes to proper metabolism of energy and cognitive and nervous system function, as well as to proper thyroid hormone production and normal thyroid gland function.
For whom ? Normal diet is generally sufficient to cover our body's iodine requirements.
The recommended intake of iodine varies according to age. Pregnancy brings increased iodine requirements, which remain for as long as breast-feeding is practised. The reference intake is set at 150 mcg daily.
