The Active Ingredient Is: Iodine (Kelp-Derived)

Iodine is a trace element essential for the production of thyroid hormones, which help regulate energy use and growth. This product sources iodine from seaweed derivatives such as kelp and bladderwrack, providing a vegan-compatible supply as part of a broader thyroid support blend.

This form is sourced from kelp and related seaweed powders present in the formulation, aligning with commonly used iodine sources in dietary supplements.

What Does Iodine Do?

Iodine supports normal thyroid function and hormone synthesis as part of standard nutritional guidance. It helps maintain the body’s normal energy metabolism and is recognised in UK and EU nutrition guidance as important for thyroid health.

EFSA and NHS-aligned information emphasise iodine’s role in supporting thyroid hormone production and overall metabolic balance.
