1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claim is calcium, which is a well recognised nutrient and is measurable in foods by established methods. Calcium occurs naturally in foods in many forms which are generally well utilised by the body. Different forms of calcium are authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/20064 and Annex II of Directive 2002/46/EC5). This evaluation applies to calcium naturally present in foods and 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, calcium, which is the subject of the health claims, is sufficiently characterised.
2.4. Metabolizm energetyczny (ID 234)
The claimed effect is “energy metabolism”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel notes that the claimed effect relates to the conversion of energy from foods into energy in the form of ATP which may be readily used by the body.
The Panel considers that normal energy-yielding metabolism is beneficial to human health.

More than 99% of the total calcium in the body is located in bones and teeth and contributes to their mass, structure and strength. Besides this structural role, calcium acts as an intracellular messenger and as a cofactor for extracellular enzymes and proteins (IoM, 1997).
3.4. Metabolizm energetyczny (ID 234)
The evidence provided by consensus opinions/reports from authoritative bodies and reviews shows that there is good consensus on the role of calcium in the stabilisation and activity of certain enzymes involved in energy metabolism, such as glyceraldehyde phosphate dehydrogenase, pyruvate
dehydrogenase, and -ketoglutarate dehydrogenase. However, the normal activity of these enzymes is not significantly affected by changes in extracellular calcium concentrations or by dietary calcium deficiency, and is practically independent of dietary calcium intake (Weaver and Heaney, 2006).
The Panel considers that a cause and effect relationship has been established between calcium and normal energy-yielding metabolism. However, the evidence provided does not establish that inadequate intake of calcium leading to impaired energy-yielding metabolism occurs in the general EU population.
4.4. Metabolizm energetyczny (ID 234)
The Panel considers that the following wordings reflect the scientific evidence: “Calcium contributes to normal energy metabolism”
5. Warunki i możliwe ograniczenia stosowania oświadczenia
The Panel considers that in order to bear the claim a food should be at least a source of calcium as per Annex to Regulation (EC) 1924/2006. Such amounts can be easily consumed as part of a balanced
diet. No Tolerable Upper Intake Levels (UL) have been established for calcium in children and adolescents; the UL for calcium in adults is 2500 mg/day (SCF, 2003).
Warunki i możliwe ograniczenia stosowania oświadczenia
Claim to be only used for Foods for sport people under the Dir. 89/398/EEC. The DRA for calcium is 1000 mg (M,F).
Agency guidance for supplements is that products containing > 1500 mg of calcium should carry the label advisory statement "this amount of calcium] may cause mild stomach upset in sensitive individuals
