Iodine

Iodine supports thyroid function and metabolic health. Routine testing helps catch deficiencies early, especially if your diet limits iodine-rich foods.

Doctor's Assessment Included

What It Measures

This test measures the level of iodine in your blood or urine. It helps assess your iodine nutritional status and thyroid function support.

Why It Matters

Iodine is essential for thyroid hormone production, which controls metabolism. Deficiency may lead to thyroid enlargement (goitre) and can affect cognitive development. Excess iodine can also disrupt thyroid function. Consult your healthcare provider for guidance.

When to Test

Testing may be recommended if you have thyroid symptoms, follow a restricted diet (especially vegan or low-salt), are pregnant or planning pregnancy, or live in an iodine-deficient region.

Symptoms

Low Levels

Symptoms of iodine deficiency may include fatigue, weight gain, feeling cold, dry skin, hair thinning, and thyroid enlargement (goitre). Severe deficiency during pregnancy can affect fetal development.

High Levels

Excess iodine may cause thyroid inflammation, hyperthyroidism, or paradoxically hypothyroidism. Symptoms may include rapid heart rate, anxiety, weight changes, and thyroid tenderness.

Lifestyle Tips

Use iodised salt in cooking and include iodine-rich foods such as seafood, dairy products, and eggs in your diet. If you follow a vegan diet, consider discussing iodine supplementation with your healthcare provider.

Frequently Asked Questions

Is iodine deficiency common?
Iodine deficiency remains a concern in some regions and populations, particularly those with limited access to iodised salt or seafood. Your healthcare provider can assess your risk.
Can too much iodine be harmful?
Yes, excessive iodine intake can disrupt thyroid function. It is important to maintain balanced intake and consult your healthcare provider before supplementing.
Do I need iodine supplements during pregnancy?
Iodine needs increase during pregnancy for fetal brain development. Discuss supplementation with your healthcare provider, as they can recommend the appropriate amount.
