The Active Ingredient Is: Iodine

Iodine is a trace mineral found naturally in kelp and other sea vegetables, providing a bioavailable iodine source in a vegan form. This nutrient plays a central role in normal thyroid function and metabolism.

This formula sources iodine from organic kelp, delivering a natural nutrient profile in a whole-food context to support thyroid health and overall nutritional wellness.

What Does Iodine Do?

Iodine participates in the production of thyroid hormones, which regulate metabolism and energy production in the body.

It helps support normal thyroid function as recognised by EFSA and NHS guidance, with kelp delivering iodine alongside naturally occurring minerals and micronutrients.

A healthy iodine intake helps maintain normal hormone synthesis and cellular health within recommended ranges, contributing to everyday metabolic processes.
