The Active Ingredient Is: Iodine (Potassium Iodide)

Iodine is a trace element essential for making thyroid hormones that steer many aspects of metabolism and development.

This form provides readily absorbed iodine from potassium iodide, with accompanying minerals included as part of the blend to help its normal function in the body.

What Does Iodine Do?

Iodine helps support the production of thyroid hormones which help regulate energy metabolism and normal nervous system function. NHS and EFSA guidance recognise iodine's role in hormone synthesis and metabolic regulation.

Dr. Zimmermann of the University of Lausanne found that iodine is essential for thyroid hormone production and metabolic regulation, reinforcing its role in keeping normal bodily functions.
