El yodo es un micronutriente imprescindible para la síntesis de hormonas tiroideas, por lo que las necesidades nutricionales de yodo aumentan durante el embarazo y la lactancia.
Los estudios epidemiológicos realizados hasta la fecha en nuestro país ponen de manifiesto un grado leve-moderado de déficit nutricional de yodo, que incide especialmente en la población infantil y en las gestantes. En nuestro medio, la única forma de garantizar un aporte continuo y regular de yodo durante toda la gestación y el período de lactancia, que permita cubrir los requerimientos de la madre y del feto en todo momento, pasa por la utilización de comprimidos de yoduro potásico, administrados profilácticamente desde la etapa preconcepcional y hasta el final de la lactancia.

Iodine is an essential micronutrient for thyroid hormone synthesis. Consequently, nutritional iodine requirements increase during pregnancy and breast feeding.
The epidemiologic studies performed to date in Spain have shown mild-moderate nutritional iodine deficiency, especially in infants and pregnant women.
In our environment, the only way to guarantee continuous and regular iodine intake throughout pregnancy and breast feeding sufficient to meet all maternal and fetal requirements is the use of potassium iodide pills, administered as a prophylactic method from preconception to the end of lactation.
