One of the most significant and under-consumed minerals today is iodine. It plays an important role in regulating the thyroid gland and metabolism. In pregnancy, iodine also helps your baby's brain and nervous system develop. Iodine deficiencies are one of the most important causes of preventable intellectual disability and brain damage worldwide.
Iodine is found in eggs, vegetables, and seafood (especially ocean or saltwater seafood). The amount of iodine in many types of food varies according to the amount of iodine in the area's soil or water.
Iodine helps brain development, particularly in the womb and first months, and can improve a child's IQ by 1.22 points. The findings, published in the journal Lancet Diabetes and Endocrinology, give an economic case for supplementation. Pregnant women need a minimum of 220 micrograms (mcg) of iodine per day while breastfeeding women about 290 mcg.
Iodine is not produced by the body and some experts believe people should be getting all the iodine they need with a varied and balanced diet. Unfortunately, in most developed nations, that's not the case.
The Birmingham team analysed 1,361 studies to establish the economic impact of IQ. They also examined data relating to iodine deficiency in pregnant women, and the effect on their children.
Louise Silverton, of Royal College of Midwives, said the study 'provides additional supportive evidence' of iodine's importance, while Dr Mark Vanderpump, of the Royal Free Hospital in London, said: 'Mild to moderate maternal iodine deficiency during pregnancy, at levels seen in UK women, is associated with impaired child cognition.'
Study author Professor Kate Jolly, from the University of Birmingham, said: 'It's time for all women living in iodine-deficient countries without universal supplementation of iodine, who are pregnant, breastfeeding, or planning a pregnancy to be advised to take a daily supplement containing iodine. Even mild iodine deficiency during pregnancy is associated with children with lower IQs.'
What Type of Iodine Supplement Should You Take?
Prenatal vitamins don't contain a reliable amount of iodine and many supplements have poor, unreliable sources.
1) Transformative Nano-Colloidal Detoxified Iodine, or Nascent Iodine:
This is a consumable form of iodine that holds an electromagnetic charge. It allows for a larger release of energy once consumed, and is very similar to bio-available forms of iodine that are produced naturally in the thyroid gland. Because of this, your body is able to recognize and assimilate it very easily. Its unique structure and form allows it to travel through the body, quicker and easier than any other Iodine supplement available.
2) Lugol's Solution Iodine:
Contains 6.3 mg of molecular iodine/iodide per drop. This solution is one-third molecular iodine (5%) and two-thirds potassium iodide (10%). Studies show that the best form of iodine is one that includes molecular iodine (I2). It has been shown that breast tissue prefers this non-toxic mono elemental-based iodine. Lugol's Solution has been shown to increase respiratory tract secretions and inhibit thyroid hormone secretion. One Malaysian study found that patients taking Lugol's solution experienced a sharp decline in unwanted hormonal secretions during a period of ten days.
3) Potassium Iodide:
Comes in tablets, with servings ranging from 0.23 to 130 mg. This closely-bound inorganic form of iodine has been shown to only offer 20% assimilation to bodily tissues. Studies show that potassium iodide blocks the uptake of radio-iodine in the thyroid gland, thus lowering the chances of developing thyroid cancer.
