What is Iodine?
Iodine was discovered in 1811 by a French scientist. Bernard Courtois came across the purple substance while trying to extract other materials from seaweed, hence the name which derives from the Greek term for violet, iodes. Our bodies can’t produce Iodine so we rely on dietary intake and supplementation. Fish and dairy products are rich dietary sources of Iodine, with white fish containing more Iodine than oily fish. Other dietary sources include vegetables grown on or around soil rich in Iodine, such as seaweed.
Benefits of Iodine
Iodine contributes to normal energy metabolism, the functioning of the nervous system and cognitive system. Iodine also contributes to the production of thyroid hormones and normal thyroid function, and the maintenance of normal skin. Those who are pregnant or breastfeeding require a higher intake of Iodine, and vegetarians and vegans may be at risk to a deficiency due to the nature of the natural food source.
