A 4-year EU2.5 million grant has been awarded to the EUthyroid2 Consortium of educational institutions and other partners working to improve iodine status both in Europe and beyond. The Horizon Europe-funded project aims to find best practice models for accessing young people, especially young women, to improve awareness of their iodine status.

Insufficient iodine during pregnancy leads to lasting brain damage that reduce a child’s IQ by 8 to 10 points. Even mild to moderate iodine deficiency at school age can reduce IQ by 3-5 points. It can easily be prevented through iodine fortification programmes, most commonly by iodization of salt for human and animal consumption.

The first EUthyroid consortium’s evaluation of iodine deficiency prevention programmes in Europe uncovered major limitations in awareness of the importance of iodine nutrition for healthy living. “EUthyroid2 will now fill important gaps in the prevention of iodine deficiency in Europe and beyond,” according to CORDIS, the European Commission’s research results organization.

The project involves implementation studies and community-based randomised controlled trials to increase iodine-related awareness in adolescents and young women up to age 24 pre- pregnancy. The multimodal interventions in two settings – educational systems and ambulatory care – will take place in eight study regions, including countries such as Norway, Denmark, Cyprus, the United Kingdom, Slovenia, Sweden, Poland, Bangladesh and Pakistan.

“Iodine deficiency imposes tremendous costs on the healthcare systems of affected regions, but can easily be prevented”, said Dr. Henry Völzke, MD, who coordinates the project for the University Medicine Greifswald, Germany. “As a public health project, EUthyroid2 is not only science, but will also serve our societies. By finding models to raise the awareness on the importance of iodine for a healthy life in young people, EUthyroid2 will lay the foundation for a cost-effective way to eradicate iodine deficiency-related disorders”.

The project brings together the expertise of renowned epidemiologists, endocrinologists, nutritionists, health economists and communications specialists from a broad range of educational institutions and countries. Other partners with broad global reach include the Iodine Global Network, Thyroid Federation International and the World Iodine Association.

The website for the EUthyroid2 project has been launched at www.euthyroid2.eu. It aims to inform the public, the scientific community, other health stakeholders, and policymakers about the progress and achievements of this project.

The website outlines the main objectives, its societal, economic and scientific implications, introduces all partners involved, and informs about major project meetings and developments as they unfold.

The appearance of the website is based on the initial EUthyroid project to retain a strong connection to the previous work. A transition line as a visual element provides a brand distinction between EUthyroid and EUthyroid2.

The first Horizon Europe-funded EUthyroid project drew global attention to the situation of the iodine supply in Europe, suggesting that up to half of the region's newborns are at risk of iodine deficiency.

EUthyroid2 aims to target the low awareness of iodine-related health risks in children and adolescents, especially young women, to ensure the prevention of iodine deficiency in Europe and beyond. Iodine deficiency is the world's largest cause of preventable mental impairment. While the health of all population groups can be affected, pregnant women and children are especially at risk. "Severe iodine deficiency may lead to lasting brain damage in infants. Even mild to moderate iodine deficiency might cause problems with development and growth", explains the leader of this project, Prof. Dr. Henry Völzke, MD, from the University Medicine Greifswald, Germany.

The EUthyroid2 website will be updated regularly and serves as an essential tool to increase awareness by communicating the project's goals, outcomes, impact, important project meetings, and other events to relevant stakeholders and the broader public.

MEDIA RELEASE (January 7, 2026, Greifswald, Germany):

EUthyroid2 announces the publication of the article: "EUthyroid2: The next step towards the elimination of iodine deficiency and preventable iodine-related disorders in Europe and beyond" in the European Thyroid Journal, 2026 Vol. 15, Issue 1.

The article discusses the problem of iodine deficiency, gives an overview of the EUthyroid2 project’s aim to target low awareness of the risks of iodine deficiency in adolescents and young women, and outlines the intervention studies conducted in two settings. The project works to identify best practice models for accessing information to educate and improve iodine status, thereby, establishing a foundation for young women to improve their own thyroid function, their general health and that of their offspring.

Thyroid disorders are a major cause of morbidity in Europe, particularly in women, and iodine status is one of the main determinants of thyroid function. Iodine deficiency disorders (IDDs) affect the entire life cycle, and women and children are especially vulnerable. Iodine deficiency during pregnancy may increase the risk of developmental impairment of the offspring. Adults living in iodine-deficient regions carry a high risk of goitre, thyroid nodules, and hyperthyroidism.

The effects of iodine deficiency impose tremendous costs on the healthcare systems of affected regions, but can be easily prevented by iodine fortification of table salt, livestock feed, plant-based alternatives and the consumption of dietary sources, such as seafood, eggs, milk, and dairy products.

The article outlines the EUthyroid2 intervention studies that are being conducted in the educational and healthcare settings, to increase knowledge and awareness of iodine nutrition among adolescents and young women. In the educational setting, students in secondary schools, high schools, and vocational schools will be targeted in six regions. In the healthcare setting, there are two levels of intervention implementation in five regions.

First, EUthyroid2 aims to raise healthcare professionals’ awareness and promote behavioural change in their practice and counselling processes. Second, EUthyroid2 aims to elevate knowledge and awareness in young women via a change in personnel action and health education, ultimately aiming to support behavioural change in terms of women’s own nutrition.

The comprehensive knowledge gained through these interventions will be instrumental in the crucial political work of not only raising awareness among the general population, but also among political decision-makers and other stakeholders in relation to promoting a euthyroid world.
