Iodine (symbol I) is a trace element. The thyroid gland contains the largest amount of iodine in the human body.

Thyroid hormones are needed for numerous processes in the body, include building proteins, enzyme activity, myelination of nerve fibres, and cell growth. Iodine is important for normal physical growth and brain development for the foetus into infancy.
