1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is selenium, which is a well recognised nutrient and is measurable in foods by established methods.
Selenium occurs naturally in foods and is authorised for addition to foods and for use in food supplements (Annex I of the Regulation (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to selenium naturally present in foods and to those forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, selenium, which is the subject of the health claims, is sufficiently characterised.
2.1. Utrzymanie prawidłowego stanu włosów (ID 281)
The claimed effect is “hair and nail formation”. The Panel assumes that the target population is the general population.
The Panel considers that maintenance of normal hair is a beneficial physiological effect.
2.2. Utrzymanie prawidłowego stanu paznokci (ID 281)
The claimed effect is “hair and nail formation”. The Panel assumes that the target population is the general population.
The Panel considers that maintenance of normal nails is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
Selenium is an essential trace element. Twenty-five selenoprotein genes have been identified in the human genome (Kryukov et al., 2003). Selenoproteins have a number of functions, comprising various catalytic roles (glutathione peroxidases, thioredoxin reductases, and iodothyronine deiodinases), structural roles, and storage and transport activities. Selenium is present in foods mainly as selenomethionine and selenocysteine. It is absorbed efficiently by the intestine over a wide range of concentrations and across a variety of different molecular forms (Bates, 2005).
3.1. Utrzymanie prawidłowego stanu włosów (ID 281)
Deficiency in selenium has been shown to result in various disorders including impairment of hair (Biesalski et al., 1995; Sunde, 2006). Clinical manifestations such as white nail beds, pseudoalbinism, alopecia and thin hair have been observed in particular in patients receiving total parenteral nutrition lacking selenium. Administration of selenium was able to restore these deficiency symptoms (Abrams et al., 1992; Kanekura et al., 2005; Masumoto et al., 2007; Vinton et al., 1987).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of selenium and maintenance of normal hair. However, the evidence provided does not establish that inadequate intake of selenium leading to impaired maintenance of normal hair occurs in the general EU population.

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 selenium as per Annex to Regulation (EC) No 1924/2006. Such amounts can be easily consumed as part of a balanced diet. The target population is the general population. Tolerable Upper Intake Levels (ULs) have been established for adults, pregnant and lactating woman, children and adolescents (SCF, 2000).
