Can I Take Too Much Iodine
Concern about iodine excess is not a reason to stop or avoid consumption of iodised salt, as the levels in salt are small enough to be tolerated by most people, except for those with a specific diagnosed thyroid autoimmune disease or any overactive nodular goitre. If in doubt, please consult your doctor.
Arent There Companion Nutrients I Should Take Before Going On Iodine
Experts on the use of iodine state there are key nutrients one should take to counter the detox of bromides, chlorine, fluoride that supplementation will promote, as well as block negative reactions to supplementation. Many start these one month before introducing iodine. Lynne Farrow termed these as Companion Nutrients, and they are:
- Selenium: 200-400 mcg per day
- Magnesium: 400-1200 mg per day
- Vitamin C: 3,000-10,000 mg per day
- Vitamins B2/B3 : 100 mg riboflavin and 500 mg no flush niacin, inositol hexanicotinate form, 1-2x per day
- Unrefined Salt : 1/2 tsp. or more per day
See thyroid patient Janes Guest Blog post about companion nutrients here:
Note about selenium: it can be quite important to test your levels before getting on selenium. Because of the MTHFR mutation, some people can have high levels, and being on selenium came make that worse with side effects to match, such as hair loss and more. Thus, if ones levels are high, the selenium is not being broken down for use, and it will be important to adequately treat the mutation.
Iodine Does Have A Role In The Bone Health Continuum
Iodine plays an important role in thyroid health because it is an essential component of thyroid hormones. That is why it is instrumental in ensuring that your thyroid gland can function properly.
Excessive iodine intake may lead to both hyperthyroidism and hypothyroidism , while a rather severe iodine deficiency can cause hypothyroidism.
As I write in the Osteoporosis Reversal Program, hyperthyroidism has been implicated in excessive bone loss, leading to osteoporosis.2
Keep in mind that thyroid hormone supplementation does not represent an increased risk of developing osteoporosis as long as normal TSH levels are maintained.
So if you have a thyroid condition or take thyroid medications, check your thyroid hormone levels regularly to insure that you are not above normal levels that could lead to bone loss.

Iodine Related Health Problem In Korean Peninsula
Although no nation-wide survey has estimated the iodine status in South Korea, several studies of iodine status in South Korean have revealed that the iodine nutritional state of South Koreans is more than adequate. In a cross-sectional study of 611 healthy South Korean preschool children, approximately two-thirds of subjects were found to have excessive iodine intake, and 3.9% of these children had insufficient iodine intake. A study performed in 540 healthy adults showed that the median UI levels in a Korean urban population were more than adequate. However, adverse effects of excess iodine were not apparent. In a study of 337 healthy South Korean adults, UI excretion had a weakly negative correlation with free T4 and showed a positive trend with TSH, whereas their levels of free T4 and TSH were within the normal ranges. Iodine excess did not directly influence the risk of goiter in 69 Korean prepubertal children.
Koreans consume excess iodine from seaweed, and iodine intake is strongly influenced by seaweed consumption. However, dose-response data derived from subjects who consume excess iodine frequently, but not continuously, during their lifetime are not available. Further population-based studies are warranted to clarify the implications of iodine excess in South Korea.
Over The Counter Thyroid Supplements
There are several thyroid supplements on the counter and it is frightening to say that;some of them actually contain thyroid hormones.
So taking them can actually harm your health.;Some of them do not list all the ingredients in it like this;study showed;that iodine was labelled in only 51% of prenatal multivitamins, rest of the multivitamins contained iodine but was not listed.;And this unlisted iodine could have interfered with your thyroid hormones.
So unless coming from a good reputable company avoid supplements which claim to support the thyroid.;

How Much Iodine You Need
According to the Food and Nutrition Board of the National Academies ,;the recommended dietary allowance for iodine in the United States ranges anywhere from 90 mcg per day for toddlers to 150 mcg for teens and adults.
Considering that one cup of plain low-fat yogurt contains about 75 mcg, 3 ounces of fish sticks contain about 54 mcg, a cup of cooked pasta contains about 27 mcg, and a quarter teaspoon of iodized salt contains about 71 mcg, that’s generally an easy amount for most people to consume.
How Your Thyroid Works
Your thyroid gland is a small gland, normally weighing less than one ounce, located in the front of the neck. It is made up of two halves, called lobes, that lie along the windpipe and are joined together by a narrow band of thyroid tissue, known as the isthmus.
The thyroid is situated just below your “Adams apple” or larynx. During development the thyroid gland originates in the back of the tongue, but it normally migrates to the front of the neck before birth. Sometimes it fails to migrate properly and is located high in the neck or even in the back of the tongue . This is very rare. At other times it may migrate too far and ends up in the chest .
The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones:thyroxine and triiodothyronine . Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism .
The pituitary senses this and responds by decreasing its TSH production. One can imagine the thyroid gland as a furnace and the pituitary gland as the thermostat.

How To Correct Iodine Deficiency
If you have an iodine deficiency, then you will want to work at increasing both iodine and selenium.
Selenium helps to protect against iodine toxicity.
Selenium is also required for the proper conversion of T4 to T3.
To increase selenium, consume brazil nuts, cod, shrimp, tuna, halibut, salmon, scallops, eggs and shitaki mushrooms.
To increase iodine, increase kelp, other forms of seaweed and of course iodized salt.
If supplementation is necessary,;start with a very low dose, perhaps 100 micrograms of iodine.
If necessary, and under the guidance of healthcare supervision, 325 mcg of kelp tablets per day should suffice.
How To Prevent And Treat Hypothyroidism
If you suffer from this condition, then your physician will prescribe prescritoin medicine, which mimicks the function of the hormone that is secreted by the thyroid gland. However, please bear in mind that treatment is at your doctors discretion and he or she will determine how much medication to give you as well as the duration of your treatment. In the event that the underlying cause of your condition is the over consumption of iodine then you can remedy this by regulating your iodine intake through adaptation of your diet. You could consult with an a dietician, nutritionist or physician to get professional help. It may also be in your best interest to do some research of what to include into your diet and present the findings to your doctor and have him or her give you the go ahead before you opt to do something on your own.

Who Tells The Thyroid To Produce And Release Hormones
The signal comes from a small gland located at the bottom of our brain called the pituitary gland. The pituitary gland produces and sends out a hormone called thyroid-stimulating hormone . TSH then tells the thyroid gland how much hormones to produce and secrete. TSH levels in your blood are rising and falling depending on your bodys needs to produce more or less thyroid hormones.
There is a third actor involved in this communication. The pituitary gland responds either directly to the thyroid hormones in the blood, but it also responds to signals from the hypothalamus, which sits above the pituitary gland as part of your brain. The hypothalamus releases its own hormone thyrotropin-releasing hormone . TRH in turn stimulates the release of TSH in the pituitary, which then signals to the thyroid gland.
This whole network is also referred to as the hypothalamic-pituitary-thyroid axis and it adapts to metabolic changes and your bodys needs.
How Much Iodine Do I Need
Adults need 140 micrograms of iodine a day.
Most people should be able to get all the iodine they need by eating a varied and balanced diet.
If you are following a strict vegan diet and do not eat any fish then you may want to consider taking an iodine supplement. Some types of plant-based milk are also fortified with iodine. If you are considering taking a supplement seek advice from a healthcare professional.
The Vegan Society has more information about iodine and vegan diets.

How Do I Know If I Have An Iodine Deficiency
A person may have low iodine levels without showing symptoms. The most reliable way to check your iodine intake is to ask your doctor to order a urine test. Your doctor may also use a blood test to ensure that your thyroid hormone levels are normal.The most visible consequence of iodine deficiency can be a goitre or enlarged thyroid gland. A goitre can be difficult to detect in the early stages, especially in children. An ultrasound is the best method to measure the size, shape and texture of the thyroid.Symptoms of hypothyroidism which can be related to low iodine levels or other forms of underactive thyroid disease include:
- Lethargy and tiredness, muscular weakness and constant fatigue
- Feeling cold
- Difficulty concentrating, slowed mental processes and poor memory
- Unusual weight gain
- Thick puffy skin or puffiness of the face
- Hair loss

Should I Test My Iodine Levels Before Supplementing
Its often advised to order an Iodine Loading Test , which is easy enough to do in your own home. You then send back your specimen, and wait for the results. These results can be important in revealing whether you might need to supplement or not. Some have chosen to do an iodine patch test on the skin, but results vary so widely that the loading test is the preferred and the most accurate determination.

Almond Milk And Thyroid Health: Good Or Bad
The majority of people who start their day with coffee prefers to enhance flavor with sugar, cream or, of course, some cows milk. People also turn to cows milk when it comes to eating cereal, drinking milkshakes, even for baking. Cows milk, however, isnt as popular as it used to be anymore.
Health conscious people are now turning to alternative options instead hemp milk, rice milk, flax milk, and coconut milk are all now commonly used by people as an alternative to cows milk. Here, we want to focus on almond milk specifically.
Almond milk has become extremely popular today. Millions of people have started to replace their cows milk with almond milk. This milk has a unique taste to it it goes great with coffee, cereal, and many other foods and drinks.
In this post, we want to take a look at how almond milk affects Thyroid health. The Thyroid is a gland that is located in a patients throat this gland plays quite a significant role in metabolism and many other functions in the human body.
We are going to take a look at whether almond milk is good or bad for the Thyroid, and what people should take into account when they do decide to start switching their cows milk for almond milk especially if a patient has been diagnosed with a Thyroid disease like Hypothyroidism.

I Am Concerned About The Use Of Salt In My Diet
Salt is a necessary part of a healthy diet. Some authorities advocate decreasing the intake of salt to prevent high blood pressure and reduce the incidence of cardiovascular disease. As most of the salt in the Australian diet comes from processed foods, The ATF suggests reducing salt intake to as low as possible and ensuring any salt used is iodised salt.
How Is Hyperthyroidism Diagnosed
There are signs and symptoms of hyperthyroidism that can be identified by a physician. Signs and symptoms of hyperthyroidism are often non-specific and can also be associated with many other causes. Laboratory tests are used to confirm the diagnosis of hyperthyroidism and probable cause. A primary care physician may make the diagnosis of hyperthyroidism, but help may be needed from an endocrinologist, a physician who is a specialist in thyroid and other endocrine diseases.
The best test to determine overall thyroid function is the thyroid stimulating hormone level. TSH is produced in the brain and travels to the thyroid gland to stimulate the thyroid to produce and release more thyroid hormone. A high TSH level indicates that the body does not have enough thyroid hormone. A TSH level lower than normal indicates there is usually more than enough thyroid hormone in the body and may indicate hyperthyroidism. When hyperthyroidism develops, free thyroxine and free triiodothyronine levels rise above normal. Other laboratory studies may help identify the cause of hyperthyroidism. Thyroid-stimulating immunoglobulins can be identified in the blood when Graves’ disease is the cause of hyperthyroidism. Thyroid peroxidase antibodies and other anti-thyroid antibodies are also seen in some disorders leading to hyperthyroidism.
