1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is magnesium, which is a well recognised nutrient and is measurable in foods by established methods.
Magnesium occurs naturally in foods and is authorised for addition to foods (Annex I of Regulation (EC) No 1925/20064 and Annex I of Directive 2002/46/EC5). This evaluation applies to magnesium naturally present in foods and to those forms authorised for addition to foods (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, magnesium, which is the subject of the health claims is sufficiently characterised.
2.7. Krzepnięcie krwi (ID 357)
The claimed effect is “normal blood clotting”. The Panel assumes that the target population is the general population.
The Panel considers that normal blood coagulation is beneficial to human health.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
Magnesium is an essential nutrient and serves as a cofactor for over 300 enzymes involved in biosynthetic processes. It is part of the Mg-ATP complex, is essential for oxidative phosphorylation and has roles in energy metabolism, mineral homeostasis, calcium metabolism, and neuromuscular and endocrine function (IoM, 1997; SCF, 2001; Volpe, 2006).
In the human body, 50 to 60% of magnesium is located in the bone. Part of it is readily exchangeable with serum and therefore bone represents a magnesium store. The remaining magnesium is mainly intracellular; extracellular magnesium represents only 1% of the total magnesium content of the body.
3.7. Krzepnięcie krwi (ID 357)
The normal mechanism for blood coagulation is a complex series of events involving the interaction of the injured blood vessel, platelets, and a number of various coagulation factors circulating in the blood.
The only reference provided does not refer to the role of magnesium on blood coagulation. The magnesium cation might act indirectly on this function through its effects on calcium. However, impaired blood coagulation is not an established symptom of magnesium deficiency.
The Panel concludes that a cause and effect relationship has not been established between the dietary intake of magnesium and normal blood coagulation.
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 magnesium 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. No Tolerable Upper Intake Levels (UL) have been established for magnesium normally present in food and beverages. An UL of 250 mg Mg/day for older children and adults has been established for readily dissociable magnesium salts and compounds like MgO in nutritional supplements, waters or added to food and beverages (SCF, 2001).

Must meet minimum requirements for use of the claim "source of [name of vitamin/s] and/or [name of mineral/s]" as per Annex to Regulation 1924/2006
Agency guidance for supplements is that products containing >400 mg of magnesium should carry the label advisory statement "This amount of magnesium may cause mild stomach upsets in sensitive individuals"
