Iodine
Iodine fuels thyroid hormone production, which drives metabolism, energy levels, and overall vitality. Adequate iodine supports peak metabolic performance.
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.
