Seagreens Iodine Lite+

Iodine contributes to:

  • The normal production of thyroid hormones and normal thyroid function
  • The normal growth of children
  • The maintenance of normal skin
  • Normal energy yielding metabolism
  • Normal cognitive function
  • Normal functioning of the nervous system
  • Ideal for Vegans who can be lacking in iodine

Seagreens® Iodine Lite+ Capsules

Iodine Lite+ is Seagreens’ new blend for children, or adults wishing merely to ‘top up’ a diet that may only sometimes be iodine sufficient.

They “would not exceed the recommended daily intake even if consumed by those with sufficient iodine” says researcher, Emily Combet. This is because the iodine is bound to protein ions and can be ‘unbound’ as needed, or excreted.

Associated research shows Seagreens® to be an effective prebiotic, which helps stabilize and prolong the absorption of its iodine. Iodine Lite+ contains four of Seagreens® NFS certified, organic wild seaweed species (and nothing else) providing a lower level of 150 micrograms of iodine per capsule than Seagreens Iodine+ within a well-documented balance of all the other nutrients.

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

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 deficiency

Half the population and 76% of girls in the UK lack dietary iodine1; 80% of women are deficient in pregnancy, associated with congenital abnormalities and low intelligence from an early age in their offspring2. The WHO regards iodine insufficiency as the greatest cause of preventable brain damage in children worldwide.

More broadly, iodine contributes to normal thyroid hormone production and thyroid, nervous system and cognitive function, normal energy yielding metabolism, and the maintenance of normal skin.

Seaweed is the richest source of bioavailable iodine, yet one of the least available minerals in our agricultural soils. Unlike other food sources – eggs, dairy, meat, fish and shellfish - it is vegetable, with a comprehensive nutritional profile.

Certain species contain all the minerals and co-factors needed for the proper transport and metabolism of iodine, including iron, selenium, zinc, copper, and vitamins A, B2, B3, B6 and C. There is a plethora of iodine supplements, from common potassium iodide to liquid solutions, and tablets and capsules which incorporate various levels of seaweed or ‘kelp’. Seagreens® has distinguished itself over the past 20 years, pioneering the production of our native seaweeds for human nutrition, and conducting independent research on iodine and the thyroid, published in the British Journal of Nutrition.

There was no adverse effect on the thyroid, normalisation of TSH (thyroid stimulating hormone), and a known safe level of iodine uptake at about 33% of the total content3.

Seagreens® Iodine+ Capsules have over 10 years’ safe use among practitioners and consumers providing at least the dietary 250 micrograms per day (µg/day) recommended during pregnancy and lactation, within a safe WHO upper limit of 17µg/kg body weight or 1000µg/day2.

Iodine Lite+ is Seagreens’ new blend for children, or adults wishing merely to ‘top up’ a diet that may only sometimes be iodine sufficient.

Recommended daily intake:

Children should take one Iodine Lite+ tablet per day, or the contents in a juice, and move to Iodine+ at about 10 years of age.

Adults who wish merely to top up their daily diet with an Iodine Lite+ capsule rather than have a full 350 µg provided by Iodine+ should also take one capsule per day.

A pure, natural, assimilable source of Iodine

Iodine is one of the most important elements and a vital food for the thyroid gland, where most of our body's iodine is stored. The thyroid in turn regulates our hormone system, which controls all the key biological functions.

Thyroid hormones, with iodine as an essential ingredient, control normal growth and development, and many other functions including immunity and fertility. Thyroxine and triiodothyromine are necessary for metabolic rate, cellular metabolism, and the integrity of connective tissue.

During the first 3 months of pregnancy iodine is particularly important to the fetus for development of the nervous system.

In the UK, 76% of school aged girls and 66% of adult women are iodine deficient**
