Algues Iode

Algues Iode offers a simple, precisely dosed marine formula: each plant-based capsule contains 280 mg of Fucus sp. and provides 150 µg of iodine. This intake represents 100% of the nutrient reference value established in the European Union for an adult. It also corresponds to the adequate daily intake established by EFSA and ANSES.

Iodine, essential for thyroid function

Once made available through digestion, iodine enters the bloodstream before being taken up by the thyroid. This gland uses it to produce the thyroid hormones T4 and T3. These hormones do not directly produce energy: they help regulate the processes that allow cells to use carbohydrates, fats and proteins to function normally.

Thanks to its supply of 150 µg per capsule, Algues Iode therefore contributes to:

  •  the normal production of thyroid hormones;
  •  normal thyroid function;
  •  normal energy-yielding metabolism.

The aim is not to artificially “stimulate” the thyroid, but to provide it with a micronutrient it naturally needs to perform its physiological functions.

Support for nervous and cognitive functions

Thyroid hormones are involved in numerous exchanges between nerve cells and in the overall functioning of the brain. By contributing to an adequate availability of iodine, the formula supports the normal function of the nervous system and the maintenance of normal cognitive function, particularly attention, comprehension and memory.

Iodine also contributes to the maintenance of normal skin. Its presence therefore enables this targeted formula to support several functions that depend on a sufficient iodine intake, without multiplying the number of ingredients.

Fucus, a naturally iodine-rich marine matrix

The term Fucus sp. refers to a seaweed belonging to the genus Fucus. These brown macroalgae live mainly on rocky coasts in temperate regions, in an area that is alternately submerged and exposed by the tides.

Their thallus—the entire visible part of the seaweed—naturally draws mineral elements from seawater. Fucus is particularly known for concentrating iodine. It also contains a matrix composed of marine fibres, including alginates, as well as various polysaccharides and polyphenols.

An iodine source steeped in history

The association between seaweed and iodine has a long history. The element iodine itself was discovered in 1811 by the French chemist Bernard Courtois from seaweed ash. Certain Fucus species, notably Fucus vesiculosus, were subsequently used in dried and powdered form in various European preparations.

Who is this product for?

Algues Iode may be particularly suitable for:

  •  adults whose diet contains few natural sources of iodine, such as fish, seafood, certain dairy products or iodised salt;
  •  people looking for a clearly defined daily intake rather than an unspecified iodine content;
  •  adults wishing to support the normal production of thyroid hormones and energy metabolism;
  •  people attentive to the normal function of the nervous system and cognitive functions;
  •  those who favour an organic marine source in a concise formula;
  •  people looking for a supplement that is easy to incorporate into their routine, with just one capsule per day.

What does the science say?

In 2016, researchers at the University of Otago in Dunedin, New Zealand, studied the effect of a daily intake of 150 µg of iodine in adults with a mildly insufficient iodine status.

The clinical trial was randomised, double-blind and placebo-controlled. It included 112 women and men aged 18 to 40. Their median urinary iodine concentration was initially 65 µg/L, a value corresponding to mild insufficiency in the group studied.

For 24 weeks, participants received daily:

  •  either 150 µg of iodine in the form of potassium iodate;
  •  or a placebo.

After 24 weeks, the median urinary iodine concentration reached 168 µg/L in the supplemented group, compared with 79 µg/L in the placebo group. The difference was statistically significant (p < 0.001).

Thyroglobulin concentration, a marker used to assess a population’s iodine status, had decreased by 12% after 8 weeks, 20% after 16 weeks and 27% after 24 weeks compared with placebo.

These results show that a daily intake of 150 µg of iodine can measurably improve the iodine status of adults even when insufficiency is mild.
