Iodine is a vital nutrient that supports thyroid health, and while the sea offers a bounty of it in seaweed, not everyone has a taste for the briny greens of the deep.
If the thought of daily seaweed snacks doesn’t float your boat, fear not, there are a variety of vegan iodine supplements that you can take instead. Whether you’re looking for high-quality sources, exceptional value, a comprehensive multivitamin, or lower doses for sensitive systems, I’ve got you covered.
Let’s explore these vegan iodine supplements!

Doctor Seaweed
- Ingredients: Organic Hebridean Ascophyllum Nodosum seaweed powder
- Quantity: 233% NRV per serving
- Price: £15 per month
Doctor Seaweed’s Pure Seaweed supplement harnesses the natural bounty of the Scottish seas, offering a 100% organic iodine source. Sustainably wild-harvested around the remote islands of the Scottish Outer Hebrides, this is a natural way of getting your daily intake of iodine.
It contains just over double your daily recommended intake of iodine, perfect for those who eat very few foods containing iodine. If you are also after a vegan vitamin B12 supplement, check out their Immunity+ supplement which contains iodine, B12, and D3.

Ethical Nutrition
- Ingredients: Potassium iodide (& other vitamins and nutrients)
- Quantity: 133% NRV per serving
- Price: £23 per month
Ethical Nutrition’s Ethical Multivitamin contains a variety of essential vitamins and nutrients that will ensure you cover all bases for your health and well-being. Each ingredient is of high quality and is well-dosed. Including the iodine, of which there is 133% of your NRV per serving.
My favourite thing about Ethical Nutrition is their paper-based packaging which can be easily recycled or composted at home, due to it containing zero bioplastics or plastic.

Nothing Fishy
- Ingredients: Bladderwrack and Irish Sea Moss
- Quantity: Approx. 5% NRV per serving
- Price: £19 per month
Nothing Fishy’s Sea Moss supplement isn’t strictly an iodine supplement, rather it is targeted as a bloating supplement. But it does contain small quantities of iodine, which are perfect for anyone who eats a lot of seaweed or gets their iodine from fortified products like plant-based milk.
Much like Doctor Seaweed and Together Health, the iodine comes from seaweed, which means you are consuming a healthy and nutritious ingredient with well-rounded benefits.
