Minimal risk for breastfeeding and infant.
Nutritional trace element which is essential for many vital functions, including the synthesis of thyroid hormones and infant neurodevelopment (Leung 2011). A deficiency affects thyroid function and cognitive performance.
Iodine is a normal component of breastmilk (Leung 2011).
Breast milk should have a concentration greater than 100 micrograms/L of iodine (*) with an average of 152 (106-199) micrograms/L (Manousou 2021, Nazeri 2018, Ares 2015) to meet the daily iodine needs of the infant, estimated at 15 micrograms / kg (Ares 2015).
Iodine supplementation increases iodine concentration in the nursing mother and breastmilk (Huynh 2016, Sukkhojaiwaratkul 2014, Mulrine 2010, Seibold-Weiger 1999).
In many regions of the world, including areas with high level of development, there is an iodine deficiency in humans, especially, among pregnant and nursing mothers. The addition of iodine to culinary salt is the most efficient way to prevent iodine deficiency in large populations, but according to countries and areas, it may be necessary to administer iodine supplements to pregnant and lactating mothers (Nazeri 2015, Donnay 2014, Caron 2006).
Recommended daily allowance from 100 to 150 micrograms for normal population that may be increased up to 250-300 micrograms during pregnancy and lactation, so most experts and health organizations recommend supplementation between 100 and 200 micrograms per day, depending on regions (Alexander 2017, Leung 2015, Donnay 2014, Mackerras 2012, Stagnaro-Green 2011, Leung 2011, Mulrine 2010, Caron 2006).
Other authors consider that there is insufficient quality evidence to determine the balance between benefits and risks of pharmacological iodine supplementation during pregnancy and lactation and suggest that this intervention should not be performed (Pallás 2014).
Iodine intakes above 500 micrograms per day are not recommended (Alexander 2017, Leung 2015).
*: 1 milligram = 1,000 micrograms; 100 micrograms = 0.1 milligram.
We do not have alternatives for Iodine (Mineral Supplements, micrograms) since it is relatively safe.
