There are many forms of potassium, but the potassium salt form of iodine is called potassium iodide (KI). This vital mineral is an excellent source of iodine. Iodine is needed for the healthy function of the thyroid gland.
If you are lacking in this mineral, or if you have too much potassium iodide in the gland, major health concerns can ensue. Potassium iodide has several clear health benefits, and many are related to the functioning of the thyroid.
The following section will outline some of the major health benefits of the mineral.
The Benefits of Potassium Iodide
Contributes to overall healthy thyroid function:
Potassium iodide is known as the thyroid mineral. It helps in keeping iodine levels in the thyroid in proper balance. When iodine levels are not optimal, it can lead to both hyper or hypothyroidism, two conditions whereby the thyroid gland produces too much or too little iodine. For this reason, potassium iodide acts as a powerful treatment and preventative mechanism for both forms of thyroid disorder through a mechanism of counteracting any less-than-optimal iodine levels due to dietary deficiencies. Potassium iodide also boosts colloid accumulation in the thyroid follicles, contributing to more healthy functioning in the important gland.
This mineral is also used prior to thyroid surgery as a preparatory mineral for the gland by reducing thyroid vascularity.
Iodine deficiency may be related to arthritis, and potassium iodide may help prevent this. 
Iodine deficiency has also been related to emotional disorders and malfunctioning glandular systems, and weight gain associated with hormonal imbalance. Dr. David Brownstein also believes that iodine deficiency may be linked to breast, ovarian, uterus and prostate cancers and cysts.
Acts as an overall expectorant:
This form of potassium stimulates the salivary glands, creating a moisturizing expectorant for treating coughs. It acts as a treatment for most respiratory tract conditions like asthma, bronchitis and emphysema, through a mechanism of reducing mucus viscosity and through augmenting respiratory tract secretions.
Acts as a protector against harmful radiation exposure:
Significant studies show that potassium iodide offers a clear protective mechanism against radiation. It does this through its ability to prevent the thyroid gland from absorbing the harmful radioactive isotopes of iodine that are released through radiation. In the event of a nuclear event, the use of potassium iodide as a deterrent is crucial, as it can reduce the risk of thyroid cancer and other future diseases associated with the thyroid.
Reduces chances of developmental problems:
Many developing countries use potassium iodide supplements to reduce the occurrence of growth and development problems, such as goiters, Hashimoto’s Disease, miscarriage, Graves’ Disease, generalized fatigue and impaired immune system function. In fact, The World Health Organization has stated that iodine deficiency is the biggest cause of mental retardation on a global scale.
Potassium iodine also aids the body in detoxification, filtering out harmful mercury, fluorides, chlorides, and bromides from our tissues and cells.
Acts as an anti-fungal:
Saturated solutions of potassium iodide have been shown to be effective in treating external forms of cutaneous sporotrichosis, a fungal infection that leads to lesions on the skin.
Recommended Iodine Supplement
I have been working for years to obtain an effective iodine supplement without the toxic alcohol base that most supplements contain. The best type of iodine supplementation is now available and is called Detoxadine®. It is a true Glycerite of Natural USP grade Iodine, extracted from a geologic formation approximately 6,000-7,000 feet below the surface of the earth, is vegan-friendly, does not contain the inefficient iodide form of iodine and is contained in a vegetable glycerin base –- not alcohol like other iodine solutions.
