Iodine is an essential constituent of the thyroid hormones, which have important modifying or permissive roles in growth and development and there is a large body of evidence indicating a crucial role for iodine in growth and development (Sadler et al., 1999; IoM, 2002; Garrow et al., 2000; Strain and Cashman, 2002). A wide spectrum of iodine deficiency disorders (IDD) have been observed, depending on the degree of deficiency and the life stage at which the deficiency occurs. These disorders range from mild goitre to the most severe forms of endemic cretinism (congenital, severe, irreversible mental and growth retardation). Other symptoms of severe IDD (arising from iodine deficiency in the foetus) include deaf-mutism, squint, disorders of stance and gait, and dry skin and swollen subcutaneous tissue (Delange, 2000; EVM, 2003; WHO, 2007).

Six references were cited to substantiate the claimed effect. Five were textbooks and one was an opinion of a scientific body. One of the references provided state that iodine supplements have been claimed to assist in the treatment of hair loss, but does not provide any further information in relation to the claimed effect (EVM, 2003). The Panel notes that the references cited did not provide any scientific data that could be used to substantiate the claimed effect.
The Panel concludes that a cause and effect relationship has not been established between the dietary intake of iodine and maintenance of normal hair.

5. Warunki i możliwe ograniczenia stosowania oświadczenia
The Panel considers that in order to bear the claims a food should be at least a source of iodine as per Annex to Regulation 1924/2006. A Tolerable Upper Intake Level (UL) has been established for iodine as 600 μg/day in adults and during pregnancy and lactation. For children and adolescents UL was established as 200 μg/day for 1-3 years, 250 μg/day for 4-6 years, 300 μg/day for 7-10 years, 450 μg/day for 11-14 years and 500 μg/day for 15-17 years (SCF, 2002). The target population is the general population.
