Iodine – trace element from the sea

Iodine is an essential trace element and a vital component of thyroid hormones. These hormones regulate many important processes in the body such as energy metabolism, bone formation and brain development. According to the World Health Organization, more than 50 countries worldwide still have an insufficient supply of iodine. Many countries therefore enrich their table salt with iodine.

Intake recommendations

The Institute of Medicine recommends an intake of 150 mg iodine per day for adults. Pregnant and breastfeeding women have an increased daily requirement because they need iodine for their own increased metabolic processes as well as for the care of the baby. According to the IOM, pregnant women have a daily requirement of 220 mg iodine per day. 290 mg are recommended for breastfeeding women. Supplements should only be taken during and after pregnancy following a medical examination and with corresponding instructions.
