PureSea®: Linking Thyroid and Immune Health

New data shows over 5 billion people (68% of the global population) lack sufficient iodine, which may lead to thyroid-related issues. Since thyroid health is key for regulating metabolism, growth, and development, iodine deficiency may affect immune function. PureSea®, a whole-food ingredient, offers a natural source of Iodine.

Why? Thyroid hormones (T3 and T4) are essential for immune function as they regulate immune cell activity and cytokine production. An underactive thyroid, often linked to low iodine intake, may cause systemic inflammation that impairs immune responses. Stress also affects the hypothalamic-pituitary-thyroid (HPT) axis which may lead to altered thyroid hormone levels and compromise immunity, while potentially causing depression and anxiety, creating a cycle that negatively impacts thyroid and immune health¹.

In response to the significant levels of deficiency, companies like Nestlé and Unilever have made iodine a key focus globally. This shift is expected to raise consumer awareness and drive demand for products that contain safe, natural sources of iodine.

PureSea® seaweed is a gold-standard ingredient, sustainably sourced from the pristine Scottish Outer Hebrides. It supports six EFSA-approved health claims as a natural source of iodine, benefiting normal thyroid function, energy yielding metabolism, cognitive health, skin maintenance, nervous system function, and healthy growth in children. With only a small amount of PureSea® required to meet recommended iodine levels, it provides an easy and effective way to boost your formulations.
