1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is vitamin B12, which is a specific group of cobalt-containing corrinoids with biological activity in humans. Recommended biochemical nomenclature restricts the term vitamin B12 for the particular form of cobalamin known as cyanocobalamin and all cobalamins exhibiting qualitatively the biological activity of cyanocobalamin. Cobalamins do not occur in plants but are synthesised by certain bacteria, fungi and algae, which constitute the ultimate source of all cobalamin found in nature (Green, 2005). Vitamin B12 is a well recognised nutrient and is measurable in foods by established methods.
Vitamin B12 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 vitamin B12 naturally present in foods and 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, vitamin B12, which is the subject of the health claims, is sufficiently characterised.
2.8. Zmniejszenie zmęczenia (ID 108)
The claimed effect is “vitamin/mineral supplementation to reduce fatigue and tiredness in situations of inadequate micronutrient status”. The Panel assumes that the target population is the general population.
The Panel considers that reduction of tiredness and fatigue is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
The two forms of vitamin B12 that function as coenzymes for metabolic reactions are methylcobalamin and 5'-deoxyadenosylcobalamin.
3.8. Zmniejszenie zmęczenia (ID 108)
The haematological effects of vitamin B12 deficiency are indistinguishable from those of folate deficiency. These include pallor of the skin associated with a gradual onset of the common symptoms of anaemia, such as diminished energy and exercise tolerance, fatigue, shortness of breath and palpitations (IoM, 2000).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of vitamin B12 and reduction of tiredness and fatigue.
4.3. Zmniejszenie zmęczenia (ID 108)
The Panel considers that the following wording reflects the scientific evidence: “Vitamin B12 can contribute to the reduction of tiredness and fatigue”.
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 vitamin B12 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. For vitamin B12 no adverse effects have been reported after high dose supplementation and no Tolerable Upper Intake Levels (ULs) have been set (SCF, 2000).
Warunki i możliwe ograniczenia stosowania oświadczenia
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.
