Active ingredients guide

Iodine: role, sources and food supplements

Iodine is an essential trace element: the body needs it in very small amounts but cannot make it. It is a component of thyroid hormones.

It was discovered in 1811 by the French chemist Bernard Courtois, in the ashes of seaweed. Even today, seafood and seaweed remain its main natural sources.

150 µg per day

The adult reference intake used on European labelling.

A trace element

Needed in tiny amounts, measured in micrograms.

Of marine origin

Fish, seafood and seaweed are its natural sources.

Recognised benefits

The recognised benefits of iodine

The European Union authorises several health claims for iodine, including the following:

Thyroid

Iodine contributes to the normal production of thyroid hormones and normal thyroid function.

Energy

Iodine contributes to normal energy-yielding metabolism.

Cognitive function

Iodine contributes to normal cognitive function.

Nervous system

Iodine contributes to normal functioning of the nervous system.

Skin

Iodine contributes to the maintenance of normal skin.

Food sources

Which foods contain iodine?

The main sources are sea fish, seafood and shellfish, seaweed and iodised salt. Dairy products and eggs also supply it, in amounts that vary depending on the animals’ feed.

The iodine content of fruit and vegetables depends on that of the soil, which is often low far from the coast. Brown seaweeds, on the other hand, concentrate a lot of it, with large differences from one species and batch to another.

Forms and intake

Potassium iodide or iodine from seaweed?

Potassium iodide is a widely used mineral salt: it allows precise dosing, for example in the form of drops. Iodine from seaweed comes from brown seaweeds such as Ascophyllum nodosum or bladderwrack (Fucus vesiculosus); a standardised extract guarantees a consistent amount of iodine.

The reference intake (RI) is 150 µg per day. Do not exceed the stated dose and avoid combining several iodine-containing products. If you have a thyroid disorder or are taking medication, ask your doctor for advice before taking any iodine.

Buying guide

How to choose an iodine food supplement?

A known amount

The iodine dose should be stated in micrograms, with the percentage of the RI.

The form

Potassium iodide, or seaweed standardised for iodine for a natural source.

Drops or capsules

Drops make it easy to adjust the dose; capsules allow combinations.

With selenium

Selenium contributes to normal thyroid function.

Frequently asked questions

Iodine FAQ

What is iodine from a natural source?

It is iodine supplied by seaweed, such as Ascophyllum nodosum or bladderwrack, rather than by an iodine salt such as potassium iodide.

Is iodine good for hair?

No health claim relates to hair. The closest authorised claim concerns the skin: iodine contributes to the maintenance of normal skin.

Does spirulina contain iodine?

Spirulina is not recognised as a source of iodine. It is mainly brown seaweeds that concentrate a lot of it.

Where can you buy an iodine food supplement?

In pharmacies, organic shops or online. At NATURAMedicatrix, iodine is available as drops or capsules, on its own or combined with other nutrients.
