Simply put, these capsules are for those wishing to focus more on achieving iodine sufficiency with a single daily capsule, and less on achieving a broad balance of all the micronutrients - for which Food Capsuyles or Food Granules are best.

Iodine+ Capsules are for adults, Iodine Lite+ for children. These capsules can also be used to boost iodine uptake in conjunction with other Seagreens® nutrition products.

Iodine Lite+contains four of Seagreens® NFS certified native wild seaweed species (and nothing else) which ensures a lower iodine level of less than 150 micrograms per capsule, within a well documented balance of all the other nutrients. 

The vegetable capsules slide open, so the content can be added to a juice or smoothie. 

Over many years Seagreens has published data on its award-winning research, the total composition of its seaweeds, and typical iodine levels across a range of native species.

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

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

It was found that the potassium iodide peaked and was rapidly excreted from the body, whereas the Seagreens iodine was more steadily absorbed, with no adverse effects on thyroid function. 

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

You can read this important research published in the British Journal of Nutrition, 2014.

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.

The European Food Standards Agency (EFSA) claims apply to all Seagreens® nutrition products because the total seaweed content contributes more than 15% of the recommended daily allowance of iodine - the RDA, now known as the RDI or Reference Daily Intake.

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 non-allergenic, additive-free 100% Organic iodine dietary supplement on the market.

And as far as we know, they still are!
