Iodine is a vital mineral essential for thyroid health, playing a crucial role in producing thyroid hormones. These hormones regulate metabolism, growth, and energy production. While iodine occurs naturally in seafood, dairy, and some grains, deficiency is common, especially in areas with iodine-poor soil. Insufficient iodine can lead to thyroid disorders, impacting overall health. It's important to ensure adequate iodine intake for proper bodily functions....


Who would benefit from testing their iodine levels?

Individuals who would benefit from iodine level testing include those with thyroid disorder symptoms, pregnant and breastfeeding women who need increased iodine, and residents of areas with iodine-deficient soils. People on diets low in iodine-rich foods like seafood and dairy, and patients with a history of radiation therapy affecting the thyroid, also gain insights from testing.

What are symptoms of low iodine?

Symptoms of low iodine include:

  • Fatigue and weakness
  • Weight gain
  • Hair loss
  • Dry, flaky skin
  • Swelling in the neck from goiter (enlarged thyroid gland)
  • Increased sensitivity to cold
  • Slowed heart rate
  • Difficulty concentrating or memory problems
  • Heavy or irregular menstrual periods in women

What foods are high in iodine?

Foods high in iodine include seafood like fish, shellfish, and seaweed, which are some of the richest natural sources. Dairy products and eggs also contain significant amounts, as does iodized salt, a common dietary addition in many countries. Additionally, certain grains and vegetables can provide iodine, though the amount varies based on the soil’s iodine content where they’re grown.

What are the benefits of iodine supplementation?

Iodine supplementation offers several benefits, especially for individuals at risk of iodine deficiency. It supports thyroid health, aiding in the production of thyroid hormones that regulate metabolism, growth, and development. For pregnant and breastfeeding women, adequate iodine is crucial for fetal and infant brain development. Supplementation can also help prevent conditions like goiter (thyroid gland enlargement) and hypothyroidism.
