Iodine is essential for an efficient metabolism and body growth and development. It is an element of the hormones thyroid and triiodotyrosine, which are both secreted by the thyroid gland. Iodine represents around 0.00004 percent of the human body mass. As with all supplements, discuss iodine with a qualified doctor before taking it.
How Iodine Works
Once iodine is absorbed into the bloodstream, the "iodine pump" transports it to the thyroid gland, where it comes into contact with oxygen and becomes iodide. It then forms the hormones thyroxin and triiodotyrosine, which promote bone growth and a higher metabolic rate.
Arthritis and Iodine
If you suffer from arthritis, your doctor may prescribe potassium iodide to reduce the symptoms, such as elbow and knee pain. Bear in mind, though, that the body tends to react better to vitamins and minerals gained through natural sources. Iodine is known to strengthen bones and reduce swelling. It comes from bread, meat, kelp and seafood and dairy products, such as cheese, butter and eggs.
Before Using Iodine
Your doctor will ascertain whether it is safe for you to take iodine supplements or not, but there are a few things you should bear in mind. Not enough studies have been done to determine whether iodine is safe during pregnancy and breastfeeding, so if you have concerns, discuss these with your doctor.
Iodine and potassium iodide interact with certain medicines, so be sure to tell your doctor what you are taking, including any natural supplements. Iodine may worsen the symptoms of lung or kidney disease, so if you suffer from one of these, your doctor may not want to prescribe iodine or potassium iodide.
Dietary Iodine
In 1924, the U.S. Food and Drug Administration, or FDA, encouraged salt manufacturers to add iodine to its products in order to prevent goiter, a common disease that caused the thyroid gland in the neck to swell. From then until the 1970s, goiter became a rare disorder, as Americans added salt to almost everything they ate. In more recent years, however, public health initiatives have promoted low-sodium diets to combat high blood pressure and water retention. Between 1988 and 1994, 12 percent of the population were seen to have low urinary iodine levels, but the National Health Nutrition and Examination Survey 2003-2004 found that things had improved. The population is still being monitored, however, because of the dangers of goiter and other iodine-deficiency disorders.
Iodine Intake
It is essential to watch your iodine intake. The FDA recommends consuming less than 2,300 mg of salt per day, which is around 1 tsp. But by eating potassium-rich foods, such as fresh fruits and vegetables, you will still get all the necessary sodium and iodine in your diet.
