1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is vitamin B6, which is a group of compounds comprising three free forms, pyridoxine, pyridoxal, pyridoxamine, and their 5'-phosphates derivatives (PNP, PLP and PMP). Vitamin B6 occurs naturally in foods, mainly as pyridoxal phosphate (animals), pyridoxine beta-glucoside (plants) and some pyridoxyl peptides (processed foods). Vitamin B6 is a well recognised nutrient and is measurable in foods by established methods.
Vitamin B6 is authorised for addition to foods (Annex I of the Regulation (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to vitamin B6 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 B6, which is the subject of the health claims is sufficiently characterised.
2.8. Udział w prawidłowym przebiegu funkcji psychicznych (psychologicznych) (ID 77)
The claimed effect is “The role of vitamins and minerals in mental performance (where mental performance stands for those aspects of brain and nerve functions which determine aspects like concentration, learning, memory and reasoning)”. The Panel assumes that the target population is the general population.

The Panel considers that contribution to normal psychological functions, which encompass cognitive and affective domains, is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka
Vitamin B6 functions as a coenzyme in a variety of enzymatic reactions in the metabolism of amino acids, one-carbon units, lipids, the pathways of gluconeogenesis, haem, and neurotransmitter biosynthesis (McCormick, 2006; Mackey et al., 2006).
3.8. Udział w prawidłowym przebiegu funkcji psychicznych (psychologicznych) (ID 77)
One of the classical symptoms of vitamin B6 deficiency is confusion (IoM, 2000), implying impairment of normal psychological functions.
The Panel concludes that a cause and effect relationship has been established between the dietary intake of vitamin B6 and contribution to normal psychological functions.
4.3. Udział w prawidłowym przebiegu funkcji psychicznych (psychologicznych) (ID 77)
The Panel considers that the following wording reflects the scientific evidence: “Vitamin B6 contributes to normal psychological functions”.
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 B6 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 vitamin B6 in children, adolescents and adults (SCF, 2000).
Warunki i możliwe ograniczenia stosowania oświadczenia
Only for products with at least 100 % RDA of vitamins
Agency guidance for supplements is that products containing >10 mg of vitamin B6 should carry the label advisory statement "Long term intakes [of this amount of vitamin B6] may lead to mild tingling and numbness"
