Iodine, in the form of salt, is a mineral that can be found in a variety of foods. It’s commonly used as a way to prevent goiters and can also be used to treat thyroid swelling and goiter.
Iodine is one of the most common minerals in the human body, and most of it is stored in the thyroid gland. When the thyroid gland is swollen, iodine levels in the body are usually elevated. High levels of iodine can be toxic, particularly if they’re not reduced in the body.
Iodine’s toxic effects are reduced when it’s in the form of iodized salt. However, because the thyroid is very sensitive, there’s a risk that high amounts of iodine in the diet could cause hyperthyroidism.
Hyperthyroidism is a condition in which the thyroid is overactive and produces too much thyroid hormones. Hyperthyroidism can lead to serious problems, such as:
- Heart irregularities
- Swelling of the thyroid gland
- Heart rhythm abnormalities
- Changes in the menstrual cycle
- Weight loss
- Muscle weakness
- Changes in the ability of the heart to pump blood
- High blood pressure

Blood pressure and iodine
The relationship between blood pressure and iodine intake is complex. Both low and high doses of iodine can cause hypertension, but that risk is more likely with higher doses.
Generally, low-iodine diets may increase blood pressure, but the risk is very small unless the diet is extremely low.
A review of studies reported that people who consume large amounts of iodine have a greater risk for hypertension, but the relationship between iodine and blood pressure is complex.
A meta-analysis of studies looked at the effect of various types of iodine supplementation on blood pressure. The study found that those who consume large amounts of iodine have a higher risk for hypertension.
The review found that high doses of iodine supplementation significantly raise blood pressure. This risk was especially high in those with preexisting hypertension or cardiovascular disease.
According to the review, most of the studies found that people who consume large amounts of iodine have a higher risk for hypertension. However, the risk of hypertension associated with iodine supplementation was small.
The authors of the review concluded that the relationship between iodine and blood pressure is complex, with some studies finding an increased risk and others not.
Other research has found that high-iodine diets are associated with an increase in blood pressure. One study reported that people who consumed large amounts of iodine had a significant increase in the risk for hypertension. However, the study did not find a direct relationship between blood pressure and the amount of iodine.
The link between iodine and blood pressure is complex, as there are many factors that can influence the effect.
How to use iodine?
You can use iodized salt to lower your blood pressure. You should aim for no more than 11 milligrams of iodine per day.
If you eat a large amount of salt, you may be at greater risk for hypertension. If you do eat a large amount of salt, you should limit your salt intake to 1 teaspoon per day.
You can also use iodized salt to treat goiters. It can be used as a goiter cure all.
The American Thyroid Association recommends that you use iodized salt for any of the following:
- Treatment of goiters
- Treatment of thyroid enlargement
- Treatment of thyroiditis
- Prevention of goiters
If you have a thyroid problem, talk to your doctor to find out if you should use iodized salt.
What are the risks of using iodine?
The risks of using iodine are minimal. The only risk is that you might react to large amounts of iodine. If you are using iodine to treat a thyroid problem, you should still talk to your doctor before using iodized salt.
It’s important to note that this is also true for other salt substitutes that are added to foods to help keep the salt taste.
Some salt substitutes contain iodine. However, the amount is very small. The risk of having too much iodine in your body is small.
It’s possible that you can get too much iodine in your body through your diet. It’s also possible to have too much iodine in your thyroid gland. If this happens, it can lead to hyperthyroidism.
There’s a small risk of iodine toxicity, which is when the body has too much iodine in the body. Symptoms of iodine toxicity include:
- Tremors and muscle weakness
- Stomach pain
If you have an iodine deficiency, you may develop goiter and goiter symptoms, such as:
- Swelling in the neck
- Swelling in the face
- Swelling in the limbs
- Difficulty swallowing
A person with a thyroid problem should get routine blood tests to check for iodine deficiency.
If you’re concerned about the effects of iodine, talk to your doctor about your iodine intake. Talk to your doctor about your diet and the amount of iodine you consume.
You can also talk to your doctor about any other medications you’re taking. Some medications can trigger an iodine reaction.
You should also talk to your doctor if you have a thyroid problem. They can refer you to a healthcare provider if you have any concerns.
What’s the treatment for iodine deficiency?
A person with a thyroid problem can get iodine from foods and supplements.
The American Thyroid Association recommends that you get iodine in the form of iodized salt. If you don’t have iodized salt, you can also use iodized salt to treat goiters.
A high-iodine diet can increase blood pressure, but this risk is small. Eating large amounts of iodine is associated with an increase in blood pressure, but the relationship is complex.
If you do have any concerns about your blood pressure, talk with your doctor
