Impact of Iodine


A policy statement from the Council on Environmental Health and published in the American Academy of Pediatrics, urged pregnant women to take iodine supplements to boost their child’s brain development. Dietary iodine, historically derived from fish and fortified salt is no longer common in the diet since fish intake has declined and most salt now comes from processed foods prepared with unfortified salt. In addition vegans, because they don’teat fish, likely have iodine deficiency1.

Iodine deficiency is also prevalent in the South East of the UK where in an Efamol/Wassen sponsored study, 100 pregnant women were recently tested in their firsttrimester. Iodine status was significant better in those taking an iodine prenatal supplements (n=42) than in those not taking one. Based on these findings, the authors stated a national survey of iodine status in UK pregnant women is required2.

 In France, a systematic literature review including 13 papers found that compared to in 1952, iodine status is better and more women are using psychomotor and neurointellectual disorders3.

Maternal iodine deficiency also:
impacts foetal and infant brain development and reduces their full potential1
increases mother and child vulnerabilities to effects of environmental pollutants including tobacco smoke1
reduces verbal IQ and reading ability of 8-9 year olds4

Maternal supplementation improves foetal and infant iodine nutrition according to a recent study of 1508 pregnant and 87 lactating women and their offspring. Iodine levels were higher in infants from mothers supplemented with 200 μg iodine daily than in those not supplemented5.

The American Thyroid Association and the National Academy of Sciences recommends1:
290 μg total daily iodide in breast feeding mothers, which generally requires 150 μg of supplemented iodide
supplemental iodine should come from potassium iodide.

Efalex Mother & Baby meets all recommendations:
provides 150 μg of iodide from potassium iodide
can be taken before and during pregnancy and while breast feeding.
