The ultimate guide of iodine


Benefits of Iodine

  •  Improves Metabolism


Your thyroid is a major factor in regulating your metabolism, and if your Iodine levels are low, you run the risk of having an under-active thyroid, and therefore a sluggish metabolism. Get your Iodine levels to a good place and all else being equal you should see an increase in your metabolic rate. It’s always a good idea to get tested to see if you do indeed have an Iodine deficiency, rather than just assuming you do and taking a supplement when it’s not needed.

  • Protects Thyroid


Because of the world we live in, each day we’re bombarded by products, foods, drinks, and lifestyles that expose us to free radicals. These attack the body, including the thyroid. Having the right amount of Iodine helps to protect the thyroid from free radical damage. Not having enough means you are leaving it susceptible to this damage, which over time can lead to additional problems and conditions.
  •  Balances Hormones


Having low amounts of Iodine can throw your hormones out of whack because it has a direct effect on your thyroid gland, which in turn regulates many of your hormones. It has also been said to help bring your libido up to its natural levels. Sometimes it can be hard to identify the symptoms of low Iodine, but together with your doctor you can figure it out, and if you find out that you’ve been running a shortage you can take steps to make things right again.
  •  Improves Hair Growth


You shouldn’t start taking massive amounts of Iodine in hopes that it will help turn around your male pattern baldness, but it has been linked to the health of the hair, and how fast it grows. This is just one sign that you may be running behind on your Iodine, if you’ve noticed that your hair is not growing as quickly, or as fully as it used to. Be sure to look for other signs before drawing conclusions.
  •  Increases Energy Levels


Not getting enough Iodine each day sets you up for not having as much energy as you would otherwise. This is because it helps with proper thyroid function, and this is a big factor in whether you feel up and ready to go, or if you feel lethargic and like you need more rest. It’s not something that is often discussed when talking about healthy energy levels, but more and more we’re finding out the important role that Iodine plays in that department.
  •  Provides Protection from Radiation


One benefit of Iodine that most people will hopefully not need to experience is that it helps protect from radiation. This can come in handy for disasters like the one at the nuclear power plant in Japan, but doctors are also using it to help patients recover from radiation treatments.
  •  Protects from Pathogens


Iodine is being considered more and more as an alternative to using antibiotics in the body to treat certain pathogens. Many people do not like the idea of taking an oral antibiotic, since it’s been known to kill off good bacteria as well as bad, and can leave the body with excess levels of Candida. But Iodine has been shown to have a similar effect while not damaging healthy bacteria that the body needs.

  •  Protects Against Cancer
In a process known as apoptosis, Iodine helps the body kill off cells that could end up leading to cancer. This is one of the most important reasons to get your Iodine levels checked at your next doctor visit, or even to schedule a particular visit to have all of your vitamin and mineral levels checked. You can’t really know what you need to focus on if you don’t know what you’re lacking, or what you’re abundant in.
All of the symptoms of iodine deficiency are related to its effect on the thyroid:
GOITER – Without adequate iodine, the thyroid progressively enlarges (develops a goiter) as it tries to keep up with demand for thyroid hormone production. Worldwide, iodine deficiency is the most common cause of thyroid enlargement and goiter (see Goiter brochure). Within a goiter, nodules can develop. Patients with a large goiter may experience symptoms of choking, especially when lying down, and difficulty swallowing and breathing.
HYPOTHYROIDISM – As the body’s iodine levels fall, hypothyroidism may develop, since iodine is essential for making thyroid hormone. While this is uncommon in the United States, iodine deficiency is the most common cause of hypothyroidism worldwide (see Hypothyroidism brochure).
PREGNANCY-RELATED PROBLEMS – Iodine deficiency is especially important in women who are pregnant or nursing their infants. Severe iodine deficiency in the mother has been associated with miscarriages, stillbirth, preterm delivery, and congenital abnormalities in their babies. Children of mothers with severe iodine deficiency during pregnancy can have mental retardation and problems with growth, hearing, and speech. In the most severe form, an under active thyroid can result in cretinism (a syndrome characterized by permanent brain damage, mental retardation, deaf mutism, spasticity, and short stature), though this is not seen in the United States. Congenital hypothyroidism due to iodine deficiency is the most common preventable cause of mental retardation in the world. Even mild iodine deficiency during pregnancy, which may be present in some women in the United States, may be associated with low intelligence in children.
