The Role of PureSea® in Optimising Thyroid Health

When the thyroid fails to produce an adequate amount of hormones, often due to insufficient iodine, it results in a condition known as hypothyroidism or an underactive thyroid. Hypothyroidism can manifest with various symptoms, including unwanted weight gain, fatigue, depressive feelings, sensitivity to cold, muscle discomfort, dry skin, and brittle hair and nails.1

Iodine is an essential dietary nutrient crucial for maintaining proper thyroid function and the production of thyroid hormones. A solution lies in incorporating a source of iodine into people's daily diets and what better way than a natural, clean label, plant-based source! Our gold-standard seaweed ingredient PureSea® provides natural iodine levels that release more gradually over time compared to synthetic alternatives.2

Europe is now considered an iodine deficient continent, affecting as many as 70% of its population.3 Addressing this issue not only stands as a necessity but also presents a substantial commercial opportunity. By assisting individuals in enhancing their thyroid function, which plays a pivotal role in various aspects of health, we can swiftly alleviate several health-related concerns through natural means.

Including PureSea® in your products, even as little as 100mg per serving, can make a significant impact on health, enabling various EFSA Approved Health Claims.

What is the Thyroid?

The thyroid, a vital component of the endocrine system, is responsible for the synthesis and release of hormones into the bloodstream. These hormones, referred to as T3 (triiodothyronine) and T4 (thyroxine), are named after the number of iodine atoms present in each hormone molecule. These thyroid hormones play a crucial role in regulating metabolism, influencing the rate at which the body's cells utilise energy.
