1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is vitamin C (L-ascorbic acid, ascorbate), which is a well recognised nutrient and is measurable in foods by established methods.
Vitamin C 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 vitamin C 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 C, which is the subject of the health claims, is sufficiently characterised.
2.3. Regeneracja zredukowanej formy witaminy E (ID 202)
The claimed effect is “regeneration of vitamin E, have synergistic effects”. The Panel assumes that the target population is the general population.
In the context of the clarifications provided by Member States, the Panel assumes that the claimed effect refers to the regeneration of the reduced form of vitamin E.
The Panel considers that the regeneration of the reduced form of vitamin E is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
The evidence provided by consensus opinions/reports from authoritative bodies and reviews shows that there is consensus on the role of vitamin C in the body (Bender, 2003; Garrow et al., 2000; IoM, 2000; NNR, 2004; Sadler et al., 1999; Levine et al., 2006; EVM, 2002). Vitamin C is an electron donor, or reducing agent, and its functions are attributable to this action (Levine et al., 2006). Vitamin C acts as a free radical scavenger in the body and as electron donor (and cofactor) for eight human enzymes, three of which participate in the biosynthesis (and cross-linking) of collagen and other components of the connective tissue, two of which are required in the biosynthesis of carnitine, one of which is required in tyrosine metabolism and two of which are required in the biosynthesis of the catecholamines adrenaline and noradrenaline (which act as neurotransmitters) and in the amidation of peptide hormones.
3.3. Regeneracja zredukowanej formy witaminy E (ID 202)
Vitamin C is an electron donor, or reducing agent, and its functions are attributable to this action. According to a report on the interaction between ascorbate and alpha-tocopherol (Niki, 1987), vitamin C as a water-soluble antioxidant can regenerate reduced alpha-tocopherol (vitamin E) as a lipid-soluble antioxidant added to liposomes in vitro (Levine et al., 2006).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of vitamin C and the regeneration of the reduced form of vitamin E.
4.3. Regeneracja zredukowanej formy witaminy E (ID 202)
The Panel considers that the following wording reflects the scientific evidence: “Vitamin C contributes to the regeneration of the reduced form of vitamin E”.
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 C 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.
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], source of protein etc (delete as appropriate)" as per Annex to Regulation 1924/2006.
Agency guidance for supplements is that products containing >1000mg vitamin C should carry the label advisory statement "this amount of vitamin C may cause mild stomach upset in sensitive individuals"
