                    The food constituent that is the subject of the health claims is manganese, which is a well recognised  nutrient and is measurable in foods by established methods.
Manganese occurs naturally in foods and is authorised for addition to foods (Annex I of Regulation  (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to manganese  naturally present in foods and those forms authorised for addition to foods (Annex II of Regulation  (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, manganese, which is the subject of the health claims, is  sufficiently characterised.

                    The claimed effect is “role of manganese within formation of tissue”. The Panel assumes that the  target population is the general population.
In the context of the proposed wording, the Panel assumes that the claimed effect refers to the normal  formation of connective tissue, including connective tissue in cartilage and bone.
The Panel considers that contribution to normal formation of connective tissue is a beneficial  physiological effect.

                    Manganese is essential as a cofactor for the metalloenzymes superoxide dismutase (SOD), xanthine  oxidase, arginase, galactosyltransferase and pyruvate carboxylase. Manganese also activates a number  of other enzymes such as various decarboxylases, hydrolases, kinases and transferases, for example  glycosyltranferases, and glutamine synthetase. Manganese is not essential for the activity of most of  these enzyme systems, which can also be activated by other metals, with the exception of  glycosyltransferases (JHCI, 2003; Buchman, 2006). Manganese deficiency interferes with normal  skeletal development in various animal species (Combs et al., 1942; Leach and Muenster, 1962; Tsai  and Everson, 1967).
Glycosyltranferases and xylosyltransferases are important for proteoglycan synthesis and thus  formation of connective tissue, including connective tissue in bone and cartilage, and these enzymes  are sensitive to manganese intake and status in animals (JHCI, 2003; IoM, 2000; Buchman, 2006).  The very few cases of manganese deficiency in humans have been induced in experimental conditions  (Buchman, 2006).
The Panel concludes that a cause and effect relationship has been established between the dietary  intake of manganese and contribution to normal formation of connective tissue. However, the
evidence provided does not establish that inadequate intake of manganese leading to impaired  formation of connective tissue occurs in the general EU population.

                    The Panel considers that the following wording reflects the scientific evidence: “Manganese  contributes to the normal formation of connective tissue”.

                    The Panel considers that in order to bear the claim a food should be at least a source of manganese 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. Although adverse health effects of  excess intake of manganese have been reported, Tolerable Upper Intake Levels (UL) have not been  established owing to lack of data on dose response (SCF, 2000).
