Iodine is one of the most important minerals for health - not least for hormone production and regulation, particularly in the thyroid gland which regulates many bodily functions. 

Each Iodine+ Capsule contains 100% whole Seagreens® wild Ascophyllum nodosum seaweed, providing typically 350 micrograms of natural iodine in a single capsule. The jar lasts for 2 months at one capsule per day.

Iodine Lite+ contains a blend of 4 Sdeagreens® wild seaweeds, providing typically 150 micrograms of natural iodine in a single capsule. The jar lasts for 3 months at one capsule per day. 

Iodine Lite+ has been developed specifically for children or where a lower daily iodine intake is required.

Both of these capsules slide open so that the content can also be taken in a juice or smoothie.

Uniquely, Seagreens® products contain no additives whatsoever and all capsules are 'Trufilled' which means that they always deliver the stated amounts per capsule.

All Seagreens® seaweed is independently monitored and free from allergens and harmful contaminants, its composition carefully studied over the past 20 years.


Independent research at Glasgow University in Scotland, compared Seagreens® wild Ascophyllum to a commonly used source of iodine - potassium iodide.

The study found that although both forms are bioavailable, the potassium iodide peaks and is quickly excreted from the body, whereas the Seagreens iodine is more gradually absorbed - with no adverse effects on thyroid function. 

Thyroid stimulating hormone (TSH) was normalised across the study group of 50 iodine-insufficient women, whose average age was 25.

The Seagreens® capsules have the added benefit of being Iodine '+'. 

The 'plus' is that Seagreens naturally contains all the other micronutrients needed for the proper transport and metabolism of iodine including selenium, tyrosine, zinc, copper, vitamins A, B2, B3, B6 and C.

In contrast, Seagreens Food Capsules contain less iodine, typically 195 micrograms of iodine per capsule, but a higher ratio of all the other nutrients.

The recommended daily use of 2 Food Capsules per day thus provides an equivalent daily intake of iodine but with double the balance of all the other nutrients.

This may be more suitable in children, pregnancy and in a wide range of nutrition-based therapeutic protocols.

Prices vary in different countries depending on the local costs of import, distribution and marketing.

The following official European Food Standards Agency claims can be made because the total content of Seagreens contributes more than 15% of the recommended daily allowance RDA (now known as the RDI Reference Daily Intake) for iodine.

Iodine contributes to normal thyroid, nervous system and cognitive function, the normal growth of children, normal energy-yielding metabolism, and the maintenance of normal skin.

Believe it or not...

When we introduced these capsules in 2000 at the request of vegan and vegetarian customers who don’t eat meat, eggs or dairy foods (the main sources of iodine) we discovered that we had made the only additive-free, iodine-rich 100% Organic dietary supplement on the market.

And as far as we know, it still is!
