Frequently asked questions

Who might need an iodine supplement?

People who eat little or no dairy, eggs or fish, including many vegans, may not get enough iodine from food. Many plant-based drinks are not fortified with iodine, so check the label.

Is seaweed a good source of iodine?

Seaweed can contain very large and variable amounts of iodine. The NHS advises not eating seaweed more than once a week, especially during pregnancy.

Does iodised salt count?

Iodised salt is less common in the UK than in many other countries. If you use it, count it towards your intake, but don't add extra salt just for the iodine.

Can I take iodine if I have a thyroid condition?

Speak to your doctor first. Extra iodine can affect some thyroid conditions and thyroid medicines.

How to choose an iodine supplement

Iodine is a trace mineral your body uses to make thyroid hormones. The NHS says adults need about 140 µg a day. The main sources in the UK diet are milk, dairy, eggs, fish and shellfish, so people who eat a vegan or dairy-free diet may get less.

Which product?

  • Iodine (potassium iodide) – vegan tablets, 200 per pack.
  • BeOrganic Iodine 150 µg – organic tablets, 100 per pack.
  • GeoNaturals Silica Iodine – liquid silicon with iodine, measured into water or juice.

How much is safe?

Follow the dose on the label. The NHS says taking 0.5 mg (500 µg) or less of iodine a day from supplements is unlikely to cause harm. Count the iodine in multivitamins and kelp or seaweed products too.

How to take iodine

Take it with a meal and a glass of water, at the same time each day.

The role of iodine

Iodine contributes to normal thyroid function and to the normal production of thyroid hormones. It also contributes to normal cognitive function, normal energy-yielding metabolism, normal functioning of the nervous system and the maintenance of normal skin.

Good to know

  • If you have a thyroid condition or take thyroid medication, speak to your doctor before taking iodine.
  • If you are pregnant or breastfeeding, ask your midwife or GP which supplement suits you.
  • Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied, balanced diet.
