The fetus is totally dependent in early pregnancy on maternal thyroxine for normal brain development. Adequate maternal dietary intake of iodine during pregnancy is essential for maternal thyroxine production and later for thyroid function in the fetus. If iodine insufficiency leads to inadequate production of thyroid hormones and hypothyroidism during pregnancy, then irreversible fetal brain damage can result. In the United States, the median urinary iodine (UI) was 168 microg/L in 2001-2002…

Iodine Supplementation in Pregnancy and the Dilemma of Ambiguous Recommendations

Based on current evidence, the recommendations given by WHO/UNICEF/ICCIDD in 2007 provide a valid guidance on the use of iodine supplements in pregnant women.

Iodine Intake and Maternal Thyroid Function During Pregnancy

Iodine supplement intake in the first half of pregnancy may lead to maternal thyroid dysfunction in iodine-sufficient or mildly iodine-deficient populations.

Iodine Requirements in Pregnancy

Meta-analyses of studies of maternal iodine supplementation in moderately to severely iodine-deficient areas have shown benefits for child development and cognitive function, although more research is warranted.

Iodine Nutrition Status of Pregnant Women in an Iodine-Sufficient Area

Pregnant women in the urban area of Tuzla had adequate iodine status except for those with restricted salt intake, which presents an increased risk to the mother as well to as the unborn child.

Apparent insufficiency of iodine supplementation in pregnancy.

New York City pregnant women were significantly less prone to iodine deficiency when provided with iodine supplementation, and when spot UI levels were used to estimate iodine sufficiency, more than 20% of supplemented women were still at risk for iodine deficiency according to WHO guidelines, suggesting that current supplementation practices remain insufficient.

Effect of iodine supplementation in Indian pregnant women on maternal and newborn thyroid function and cognitive development

Whether iodine supplementation to pregnant women improves maternal and newborn thyroid function, pregnancy outcome, birth weight, infant growth and cognitive performance is investigated and the association of maternal depression, and thyroid function during pregnancy is assessed.

Teratology public affairs committee position paper: iodine deficiency in pregnancy.

It is concur with the ATA recommendation that all pregnant and lactating women should ingest (through diet and supplements) 250 micrograms of iodine daily, and recommends that all mothers-to-be take daily iodine supplementation of 150micrograms.

Iodine nutrition status in pregnant women in Mexico.

Based on the median UIC, iodine intake in Queretaro, Mexico, is slightly above requirements during the first two trimesters, and adequate in the third trimester, and the wide Mexican universal iodized salt program seems to supply adequate dietary iodine to pregnant women without health insurance in this region.



Sources of dietary iodine: bread, cows' milk, and infant formula in the Boston area.

The public is aware of the need for adequate dietary iodine intake and should be aware that ingredient lists do not reflect the iodine content of foods.

Adequate iodine intake--the good far outweighs the bad.

The administration of 250 mg potassium iodide daily for an average of 4 months in mildly iodine-deficient Germany induced subclinical hypothyroidism in some patients, which suggests that the longer period of a mild increase in iodine intake in euthyroid patients with Hashimoto’s thyroiditis and a normal ambient iodine intake was associated with at least a partial adaptation to the excess iodine.

Iodine in human milk: perspectives for infant health.

The newly recommended Adequate Intake of iodine for infants is 110 microg/day for infants 0-6 months and 130 microg / day for infants 7-12 months.

Iodine nutrition in the United States. Trends and public health implications: iodine excretion data from National Health and Nutrition Examination Surveys I and III (1971-1974 and 1988-1994)

The percentage of people excreting low concentrations of iodine (UI, <5 microg/dL) increased in all age groups, and the findings in 1988-1994 are not indicative of iodine deficiency in the overall U.S. population.

Iodine Supplementation

Iodine-induced hyperthyroidism and other adverse effects can be almost entirely avoided by adequate and sustained quality control and monitoring of iodine supplementation which should also confirm adequate iodine intake.

Urinary iodine concentration: United States National Health And Nutrition Examination Survey 2001-2002.

The NHANES 2001-2002 data confirm the current stability of the U.S. iodine intake and continued adequate iodine nutrition for the country.

TSH and the prevalence of antithyroid antibodies are greater in females, increase with age, and are more in whites and Mexican Americans than in blacks, which supports the usefulness of screening for early detection.

Perchlorate and iodide in dairy and breast milk.

On the basis of limited available data, iodide levels in breast milk may be significantly lower than it was two decades ago and recommended iodine intake by pregnant and lactating women may need to be revised upward.
