Could My Health Issues Be an Iodine Deficiency?

Many everyday health concerns can sometimes be traced back to overlooked nutritional gaps, and iodine is one of the most common culprits. This essential mineral plays a vital role in thyroid function, metabolism, and overall energy balance, yet it’s often missing from modern diets. When levels fall short, the body can respond in subtle but disruptive ways, from persistent fatigue to changes in mood and weight. Understanding the link between iodine and your health can shed light on symptoms that might otherwise remain unexplained.

Key Notes

• Iodine is essential for thyroid hormone production, metabolism, growth, brain, and bone development.
• Low iodine levels can cause hypothyroidism with symptoms such as fatigue, weight gain, coldness, dry skin, hair loss, muscle weakness, and difficulty concentrating.
• Causes of deficiency include low dietary intake (vegan/vegetarian diets, lack of iodised salt), goitrogens in foods (soy, cassava, cruciferous vegetables), environmental toxins, selenium deficiency, and pregnancy.
• Symptoms of deficiency can include goitre, diarrhoea, slowed metabolism, and in severe cases during pregnancy, miscarriage, stillbirth, or birth defects.
• Iodine’s role in the body: Balances estrogen and helps prevent estrogen dominance, supports liver detoxification of toxins, plastics, and heavy metals, and maintains healthy thyroid function and hormone production.
• Natural iodine sources include sea kelp, seafood, and sea salt (though sea salt contains little iodine).
• Iodine supplements can support thyroid health, pregnancy, fibrocystic breast disease, and protection against radiation — but dosage should be guided by a doctor, as both too little and too much iodine can be harmful.

What Is Iodine?

The production of thyroid hormones, which control metabolism, growth, and development, particularly in the brain and bones throughout fetal and early childhood stages, requires iodine, an essential trace mineral. It is a non-metallic chemical element that is present in soil and oceans and needs to be consumed through a variety of meals.

How Do You Know If Your Body Is Low In Iodine?

If you have inexplicable symptoms such as weariness, weight gain, coldness, dry skin, hair loss, and muscle weakness, you may have an iodine deficit. These symptoms are prominent indicators of hypothyroidism, which is frequently brought on by insufficient iodine. A physical examination, thyroid function blood tests, and even a urine test to gauge recent iodine consumption can all help a doctor confirm a diagnosis; however, individual urine tests are less accurate for chronic deficit.

What Depletes Iodine In the Body?

Low dietary intake (from vegan/vegetarian diets or absence of iodised salt, for example), high goitrogen levels (found in soy, cassava, and cruciferous vegetables), exposure to perchlorates and thiocyanates, selenium deficiency, and pregnancy are some of the reasons that cause the body to lose iodine. These causes cause a deficit and possible swelling of the thyroid gland by interfering with the synthesis of thyroid hormones and iodine intake.

What Are Some Symptoms Of Low Iodine?

Fatigue, weight gain, coldness, dry skin and hair, diarrhoea, and trouble focusing are some of the symptoms of insufficient iodine, which are frequently related to thyroid function. Additionally, you might observe a goitre, or apparent enlargement of the thyroid gland, on your neck. Severe deficiencies during pregnancy may result in stillbirth, miscarriage, or birth abnormalities, including intellectual disability.

What Does Iodine Do in the Body?

• It buffers estrogen in estrogen dominance.
• It helps prevent a person from developing estrogen dominance – i.e. heavy periods, cysts in the breasts, cysts in the ovaries, extra weight gain in the lower section of the body.  It can increase the risk of cancer in these organs.  In men, it can even develop into prostate cancer.
• Low Iodine can cause high estrogen, and it affects the thyroid, creating a hypothyroid condition.  Low Iodine can also cause a lack of thyroid hormones, which leads to hypothyroidism.
• Iodine is involved in detoxing the liver in the phase I and phase 2 detox.  It is used in phase 2, which is detoxing of plastics, herbicides, fungicides and heavy metals, which are endocrine disruptors.  If you don’t have enough Iodine, these toxins back up into the liver and into the body, causing a host of illnesses.

How Can Cholesterol Connect to Hypothyroidism and a Lack of Iodine?

If you have a hypothyroid condition (slow thyroid), your ability to metabolise cholesterol is poor. We need cholesterol, and this means the cholesterol in your body is raised and not used for certain things.

Cholesterol is needed to process Vitamin D, and it’s needed to create bile. Bile that is produced by the liver and stored there is made by Cholesterol, and if you don’t have enough cholesterol, whether it’s because you have a lowered hypothyroid issue or you are using statins for cholesterol, you could develop a bile deficiency.

If you have a bile deficiency with elevated cholesterol, you end up with a concentration of cholesterol, causing gallstones and bile sludge. These issues can cause pain after eating in your stomach, pain under the rib cage, and pain in the right shoulder.

What Are the Natural Ways to Get Iodine in Your Body?

There are many ways you can increase Iodine in your body. Some of the most natural ways include:

• Sea Kelp in food or in capsule form
• Seafood – shellfish and sea fish
• Sea Salt – however, very little iodine in sea salt

What Can Iodine Supplements Help With?

Iodine shortage is important for thyroid function, brain development, and embryonic development; it can be prevented and treated with iodine supplements. In addition to helping with illnesses like fibrocystic breast disease and shielding the thyroid from radiation, they can enhance metabolic function and aid during pregnancy and lactation. To make sure you get the proper quantity, though, you must speak with a doctor before taking supplements because both too little and too much iodine can be detrimental.

So, a lack of iodine can create many issues in the body, and tests are not always done for these things.
A simple test to see if I have a lack of iodine – Another way to test if you have enough iodine in your body. Buy Iodine drops from your pharmacy/drug store and place a drop or 2 on the inside of your lower arm with a cotton swab. Leave it there with a band-aid for about 5 hours. If the iodine colour has disappeared within that period, you may have an iodine deficiency. If the stain is still there, your iodine levels are good and no need to worry.
