Iodine is an essential trace mineral that the body uses to produce thyroid hormones. These hormones are crucial for regulating metabolism, energy production, growth, and development, especially brain development in children and during pregnancy.
Symptoms of iodine deficiency can include fatigue, weight gain, feeling cold, and swelling in the neck (goitre). If you are concerned about iodine deficiency, it's best to speak with a healthcare professional for advice and diagnosis.
Iodine is naturally found in certain foods, particularly seafood (like cod and tuna), seaweed, dairy products, and eggs. Iodised salt is also a common source. However, dietary intake can vary, and supplements can help ensure consistent intake.
