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), with varied bioavailability as vitamin B6. Vitamin B6 is a well recognised nutrient and is measurable in foods by established methods.
Vitamin B6 it is authorised for addition to foods (Annex I of the Regulation (EC) No 1925/20064 and Annex I of Directive 2002/46/EC5). 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.

3. Naukowe uzasadnienia wpływu na zdrowie człowieka

3.6. Zdolności umysłowe (ID 185)

A total of eight references were provided in the consolidated list to support this claim. These included three reviews, one textbook and four human studies where the effect of vitamin B6 on symptoms of depression, cognition, ageing, premenstrual syndrome and memory performance was assessed. The daily doses of vitamin B6 supplementation ranged from 40 - 600 mg.
The Panel notes that the evidence provided for substantiation of the claim relates to studies with vitamin B6 at intakes above the Tolerable Upper Intake Level (UL) (25 mg; SCF, 2000) and that the proposed conditions of use refer to intakes up to three times the UL. The Panel considers that this claim (the proposed wording of this claim) encourages excess consumption of vitamin B6 and therefore does not comply with the criteria laid down in Regulation (EC) No 1924/2006 (Article 3c).

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 (UL) have been established for vitamin B6 in children, adolescents and adults (SCF, 2000).
