Iodine is a trace mineral essential for normal thyroid function and metabolism. This product provides a highly absorbable form of iodine sourced from kelp and rock crystals and is water-soluble for easy uptake.

What Does Iodine Do?

Iodine is involved in thyroid hormone synthesis, which supports metabolic processes and energy production in the body. It also plays a role in cognitive function in line with scientific literature and EFSA/NHS-style guidance.

Dr. Zimmermann of the University of Calgary found that iodine is important for thyroid function and metabolism, contributing to energy regulation and cognitive performance according to clinical evidence cited in reputable sources.
