1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claims is thiamin (vitamin B1), which is a well recognised nutrient and is measurable in foods by established methods.
Thiamin occurs naturally in foods and 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 thiamin 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, thiamin, which is the subject of the health claims, is sufficiently characterised.

2.1. Zmniejszenie zmęczenia (ID 23)

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.

3.1. Zmniejszenie zmęczenia (ID 23)

Ten references were provided for the scientific substantiation of this claim.
A review article described the role of the B vitamin family on mitochondrial energy metabolism. Another review article on the effect of physical activity on thiamin, riboflavin and vitamin B6 requirements described a study which examined the effect of multi-vitamin deficiency (including thiamin deficiency) on work performance. The Panel notes that no conclusions can be drawn from a multi-vitamin depletion study for the substantiation of a claim on thiamin alone.
A review article on the effect of vitamin and mineral status on physical performance describes the effects of impaired micronutrient status on human physiological function during exercise and physical performance. The Panel considers that no conclusions can be drawn from this reference for the scientific substantiation of the claimed effect.
The remaining references were six nutrition textbooks and one opinion on dietary reference intakes for several vitamins and minerals including thiamin (IoM, 1998); tiredness and fatigue were not included in the symptoms of thiamin deficiency.
The Panel concludes that a cause and effect relationship has not been established between the dietary intake of thiamin and 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 thiamin as per Annex to Regulation (EC) No 1924/2006. Such amounts can be easily consumed as part of a balanced diet. Tolerable Upper Intake Levels (UL) have not been established for thiamin in children, adolescents and adults. The target population is the general population.
