The Active Ingredient Is: Iodine (Kelp-derived and potassium iodide)

Iodine is an essential trace mineral required for normal thyroid hormone production and overall endocrine health.

This formula combines iodine sourced from kelp with potassium iodide to support bioavailability and thyroid function as part of a balanced nutrient matrix.

What Does Iodine Do?

Iodine is involved in the synthesis of thyroid hormones built from iodine and the amino acid L-tyrosine, supporting normal hormone production.

These fundamental processes contribute to maintaining normal metabolic activity and energy production in the body, with iodine and tyrosine acting as key building blocks for T4 and T3 hormones.
