Iodine

What is it?

Iodine is a trace mineral essential for the production of thyroid hormones, which control the metabolism of the body, that is the rate at which you burn calories.

Function How it helps
Thyroid function

The primary function of Iodine is in combination with the amino acid tyrosine in order to manufacture active thyroid hormone.

Weight control The thyroid hormone controls the rate at which fats are burned to produce energy. People with an under-active thyroid (hypothyroidism) will be more prone to obesity.
Breast health A lack of iodine in breast tissue may make the breast cells more sensitive to the hormone oestrogen, which in turn, triggers the growth of benign cysts which may cause pain and swelling in the breast.
