Iodine In Our Bodies
Hypothyroidism (having low thyroid function) is a known cause of intellectual disability (lowered IQ). For normal thyroid hormone levels, we need adequate levels of iodine in the body. World wide iodine deficiency affects almost 2 billion people. In the US, iodine levels are dropping due to a number of factors, including less use of salt and the use by many of Kosher or sea salt that is not supplemented with iodine. During pregnancy, and while breast feeding, our dietary iodine needs are increased. The WHO (World Health Organization) and ICCIDD (International Council of Iodine Deficiency Disorders) suggest an iodine intake of 200-300 micrograms a day for pregnant and lactating women.
Since only 20% of pregnant women are taking an iodine-containing supplement, this is an important step even pregnant woman should take: MAKE SURE YOU TAKE 150-300 MICROGRAMS OF IODINE DAILY WHILE PREGNANT OR BREASTFEEDING. Two of three prospective studies demonstrated improvements in child cognition! You should also use a prenatal that contains iodine.
I highly recommend that all pregnancies be supported with not just a prenatal that contains iodine, but also 5000 IU a day of Vit D (most people are severely deficient in Vit D), omega -3 purified fish oil, and eat organic foods, avoiding fish and GMO foods.
