Introduction to Iodine

Support your physical and mental vitality with a natural, pure, and highly absorbable source of iodine!

Iodine is an essential trace element for the body’s proper functioning. However, our body cannot produce it: it must therefore be supplied through diet, mainly via fish, seafood, and seaweed.

Yet today, modern lifestyles sometimes make these intakes insufficient—especially if you follow a vegetarian or vegan diet, or simply consume little fish.

To help you meet your daily needs, we have selected a 100% natural and certified organic marine iodine source: PureSea®, derived from Ascophyllum nodosum seaweed (also known as knotted kelp).

Wild-harvested in the pristine waters of the Outer Hebrides in Scotland, this seaweed undergoes an exclusive cold-drying process that naturally preserves its nutrients and guarantees excellent bioavailability.

Each capsule provides 150 µg of iodine, representing 100% of the Reference Intake. A simple, natural, and effective solution to support your energy, concentration, and thyroid balance every day!

Who is our Organic Marine Iodine for?

Our Organic Marine Iodine is designed for anyone wishing to secure their daily iodine intake. Certain profiles benefit from it in particular.

  • You consume few seafood products
    Fish, shellfish, and seaweed are the primary dietary sources of iodine. If you eat them less than twice a week, your intake can quickly become insufficient. [1] Daily supplementation provides a simple way to bridge this gap.
  • You follow a vegetarian or vegan diet
    Without fish and dairy products, iodine intake is often reduced in these diets. Our Organic Marine Iodine is derived from seaweed, a 100% plant-based, natural source that is fully suitable for vegan diets. Pair it with our Organic Spirulina to support your intake of plant proteins and other trace minerals.
  • You care about your cognitive function
    Iodine contributes to normal cognitive function and the normal functioning of the nervous system (EFSA authorized claims). [2] Securing this daily intake is a simple step to support your mental energy, especially during periods of high intellectual demand. Consider combining it with our EPAX® Omega 3, which also contributes to normal cognitive and heart function.
  • You want to support your thyroid function
    Iodine is essential for the production of thyroid hormones, which regulate overall metabolism. The EFSA recognizes that iodine contributes to normal thyroid function and the normal production of thyroid hormones. [2] If you have any concerns regarding your thyroid function, a medical check-up (TSH level) is recommended before starting a course; see also our Precautions for Use.
  • You support your daily energy levels
    Iodine contributes to normal energy-yielding metabolism (EFSA authorized claim). [2] For a comprehensive approach, you can pair it with our Bisglycinate Magnesium, which helps reduce fatigue.

Ingredients

Knotted wrack thallus powder* (Ascophyllum nodosum (L.) Le Jolis) PureSea®, bulking agent: acacia gum; plant-derived capsule (glazing agent: hydroxypropyl methylcellulose).
* Ingredient from organic farming.

Precautions for use

Diagnosed thyroid disorders: In case of diagnosed hyperthyroidism or hypothyroidism, do not use without medical advice.

Treatment with levothyroxine or antithyroid medications: You must consult your doctor before use.

Other drug interactions: Lithium and amiodarone may interact with iodine. If you are taking any of these treatments, seek advice from a healthcare professional.

Pregnancy and breastfeeding: Iodine requirements increase during these periods, but dosage must be adjusted under medical supervision. Always consult a healthcare professional before taking any supplement.

After age 40: As thyroid nodules become more common with age, a prior thyroid assessment (TSH level) is recommended before starting supplementation.

Combining multiple iodine sources: Our Multivitamins already contain iodine. Keep this in mind to avoid double dosing.

Do not exceed the recommended daily dose (1 capsule = 150 µg). The upper safe limit established by EFSA is 600 µg/day.

Storage: Store in a cool, dry place, away from heat and light. Keep out of reach of children.

Why choose our Iodine?

Iodine is one of those trace elements we rarely hear about until we discover we are running low on it. Yet, when it comes to choosing the right supplement, dosage is only half the story: the origin of the iodine and the accuracy of its concentration are crucial. Between synthetic potassium iodide on one end and raw seaweed with highly variable dosages on the other, finding the right option can be a real headache.

Our choice : PureSea®, a patented ingredient derived from Ascophyllum nodosum seaweed (knotted kelp), wild-harvested in the pristine waters of the Outer Hebrides in Scotland. A brown seaweed from the cold waters of the North Atlantic, dried using a patented low-temperature process, standardized in iodine, and tested batch by batch. The result : 150 µg of iodine per capsule (100% of NRVs), a gradual release enabled by the seaweed's natural matrix, and a formula that is certified organic, vegan, and made in France.

The PureSea® Seal : The Gold Standard for Marine Iodine

PureSea® is a patented ingredient derived from Ascophyllum nodosum seaweed, standardized in iodine and tested batch by batch. This dual requirement guarantees a reliable and consistent dosage where raw seaweeds can show sharp variations in concentration a genuine risk with this type of raw material. With PureSea®, what you read on the label is exactly what you get, in every capsule, in every batch.

A Patented Cold-Drying Process

Ascophyllum nodosum seaweed is dried at low temperatures using the patented PureSea® process. This gentle drying preserves the seaweed's natural iodine and nutrient content, whereas high-temperature industrial processes can degrade them. It is a hidden technical step, yet it makes all the difference to the product's final quality.

Sustained and Gradual Release (Combet 2014 Study)

Naturally bound to the seaweed's fibers, iodine is released more gradually than synthetic potassium iodide. As highlighted in the clinical study by Combet et al. (2014) [3], published in the British Journal of Nutrition, the release of seaweed-derived iodine is slower. Result : a more stable availability over time, rather than an absorption peak that is rapidly excreted in urine.

100% of NRVs in a single capsule, a 4-month supply per bottle

Each capsule provides 150 µg of iodine, representing 100% of the Nutrient Reference Value for an adult. A simple format: one capsule a day and a bottle of 120 capsules = a 4 month course of treatment. At 150 µg, we remain well below the upper safe limit set by EFSA (600 µg/day) [2] representing just 25% of this limit, a comfortable safety margin.

Organic, Vegan, Sustainable Harvesting, Made in France

Our iodine supplement is certified organic, GMO-free, and preservative-free. Its capsule is of plant origin (HPMC) and the formula is suitable for vegetarian and vegan diets. The Ascophyllum nodosum seaweed is harvested without uprooting its base, allowing it to regrow naturally and preserve the marine ecosystem. The finished product is made in France in a laboratory complying with the strictest quality standards. The bottle is made of 100% recycled and recyclable R-PET.

What our customers say about Novoma Iodine

Read testimonials from those who use our products daily! 💚

Notre équipe Agathe

Agathe Demazier

R&D Manager, Novoma

Iodine is a nutrient whose intake has historically been difficult to target : too little poses a thyroid risk, but so does too much. We calibrated our formula to 150 µg per capsule exactly the recommended daily intake using certified organic seaweed with controlled levels, a critical point given the natural variability of iodine levels in seaweeds.

When will I feel the effects?

  • Each day

    Take 1 capsule with a large glass of water, during a meal. Consistency is essential—it ensures a steady intake of iodine over the weeks.

  • 2 à 4 semaines

    Initial benefits may become noticeable, particularly for individuals with initially low intake levels. They most commonly relate to energy levels and focus.

  • 1 to 3 months

    The benefits stabilize and consolidate as your iodine intake becomes consistent.

  • 4 months

    This is the recommended duration of use, equivalent to one full bottle. It delivers long-term support for thyroid, cognitive, and energy functions.

Your questions about Iodine

Effects

How to tell if your body needs iodine?

Insufficient iodine intake can sometimes result in unusual fatigue, difficulty concentrating, sensitivity to cold, or dry skin. However, these signs are not specific and can have many causes.

If in doubt, only a healthcare professional can assess your needs using an appropriate check-up.

Important:our supplement is not recommended for people suffering from a thyroid disorder or undergoing thyroid treatment without medical advice.

When should you not take iodine?

Our Organic Marine Iodine is not recommended if you have a diagnosed thyroid disorder, whether it is hyperthyroidism or hypothyroidism, as well as in the case of treatment with levothyroxine or antithyroid medication. If you are pregnant or breastfeeding, seek the advice of a healthcare professional before any supplementation. See the Precautions for usesection for details.

Can iodine be taken after the age of 40?

Yes, there is no general prohibitionagainst iodine supplementation after age 40. Caution is mainly advised because thyroid nodules are more common with age, and an excess of iodine can in some cases stimulate them. Before starting a course of supplements, it is best to have a thyroid panel (TSH) done, a simple test prescribed by your doctor.

What is the recommended daily dose of iodine?

ANSES recommends an iodine intake of 150 µg per day for adults. Our iodine food supplement provides exactly 150 µg per capsule, which is 100% of the Nutrient Reference Values. The upper safety limit set by EFSA is 600 µg per day, so one capsule remains well below this threshold.

Can this supplement be taken during pregnancy or while breastfeeding?

Iodine is essential during pregnancy and breastfeeding, periods during which requirements increase. However, seek the advice of a healthcare professional before any supplementation, the dosage must be adapted to your situation, under medical supervision.

What is the duration of an iodine treatment?

Our bottle of 120 capsules provides a 4-month course, at a rate of one capsule per day. You may repeat the course if needed, preferably after medical advice in case of prolonged supplementation.

Why choose PureSea® marine iodine?

  • Guaranteed and secure efficacy : Unlike raw algae whose iodine content varies, the patented PureSea® ingredient is standardized and controlled batch by batch. This guarantees precise, stable, and completely reliable dosing.
  • Natural and progressive assimilation : Thanks to a cold-drying process that preserves its nutrients, this bioavailable iodine is bound to the algae fibers. It is slowly released by the body, thus avoiding the brutal absorption peak of synthetic iodine.
  • An eco-responsible and pure commitment : The Ascophyllum nodosum algae is harvested sustainably to preserve the marine ecosystem. Furthermore, the formula is certified 100% Organic, GMO-free and preservative-free, and is perfectly suitable for vegetarians and vegans.

In short : Choosing PureSea® means opting for natural, highly assimilable, perfectly dosed, and environmentally friendly marine iodine.

What is the difference between marine iodine and synthetic iodine?

The main differences between marine iodine and synthetic iodine are found primarily in:

  • Marine (natural) iodine : Derived from algae, it is bound to organic components (such as fibers). It is assimilated by the body in a progressive, stable, and gentle manner, without saturating the body.
  • Synthetic (chemical) iodine : Manufactured in a laboratory (often in the form of potassium iodide), it is purified but assimilated very quickly, which can cause an abrupt absorption peak in the blood.

In summary : Marine iodine offers a natural and diffused release, while synthetic iodine acts immediately and more massively.

Are there any drug interactions?

Yes. Iodine can interact with certain treatments, including levothyroxine, antithyroid drugs, lithium, and amiodarone. If you are on any of these treatments, seek advice from a healthcare professional before starting iodine supplementation.

When will I feel the effects?

The initial effects of the course are generally felt within 2 to 4 weeks, with a noticeable improvement in fatigue and concentration. These benefits then consolidate over a period of 1 to 3 months as your iodine intake becomes consistent; ideally, the course should be extended up to 4 months to provide optimal, long-term support for your thyroid and cognitive functions.

Are there any side effects?

Overall, side effects are rare. You may experience thyroid disorders, digestive issues, or skin reactions (rashes or acne). If in doubt, stop taking the supplement immediately and consult a healthcare professional.

What supplement can I combine Iodine with?

Our iodine food supplement can naturally be combined with other Novoma supplements for more comprehensive nutritional coverage:

  • Epax® Omega 3: EPA and DHA contribute to the maintenance of normal cognitive and cardiac function, in addition to your iodine regimen.
  • Zinc Bisglycinate: contributes to the normal functioning of the immune system and normal cognitive function, in synergy with iodine.
  • Magnesium Bisglycinate: helps reduce fatigue and contributes to the normal functioning of the nervous system.

Good to know: Novoma Multivitamins already contain iodine. Keep this in mind if you are considering combining these two supplements.

What is the duration of an iodine treatment?

Our 120-capsule bottle provides a 4-month supply, at a rate of one capsule per day. You can repeat the course if needed, preferably after medical advice in case of prolonged supplementation.

Does iodine have benefits for hair?

Iodine contributes to normal thyroid function, and thyroid hormones play a role in the hair cycle. This explains why some individuals with insufficient iodine intake notice changes in their hair. However, iodine is not specifically recognized for its hair benefits : it provides indirect support via thyroid function. For a targeted hair care approach, see our Hair Formula.

How do you know if your body needs iodine?

An insufficient iodine intake can manifest through several non-specific signs : persistent fatigue, difficulty concentrating, dry skin, or sensitivity to cold. These signs can have many causes, and iodine is only one hypothesis among others. If you have any doubts, a thyroid assessment (TSH) prescribed by a doctor is the best way to evaluate your iodine status and guide appropriate supplementation.
