The food constituent that is the subject of the health claim is vitamin C (L-ascorbic acid, ascorbate), which is a well recognised nutrient and it is measurable in foods by established methods.
Vitamin C occurs naturally in foods. Ascorbic acid and its salts (ascorbates) are the forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/20065 and Annex II of Directive 2002/46/EC6). 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 claim, is sufficiently characterised.

The claimed health relationship is “respiratory health” and “soothing/relief in case of tickle” in the upper respiratory tract. The Panel assumes that the target population is the general population.
Respiratory health is too broad for a scientific evaluation. However, “relief in case of tickle” in the throat could be assessed if adequate validated tests were available.
The Panel considers that relief in case of irritation in the upper respiratory tract might be beneficial to health.

The evidence provided by consensus opinions/reports from authoritative bodies and reviews shows that there is good consensus on the role of vitamin C in the body (Bender, 2003; Garrow et al., 2000; IoM, 2000; NNR, 2004; Sadler et al., 1999; Shils et al., 2006; EVM, 2002). Vitamin C is an electron donor, or reducing agent, and its functions are attributable to this action (Shils et al., 2006). On the one hand, vitamin C acts as a major 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 them are required in the biosynthesis of carnitine, one in tyrosine metabolism and two in the biosynthesis of the catecholamines adrenaline and noradrenaline (which act as neurotransmitters) and in the amidation of peptide hormones.

One reference was cited to substantiate the health claim which is the administrative guidance to present applications for the registration of cough drops in Switzerland.
The Panel concludes that a cause and effect relationship has not been established between the dietary intake of vitamin C and relief in case of irritation in the upper respiratory tract.
