In the context of the proposed wordings and clarifications provided by Member States, the Panel assumes that the claimed effects refer to relief in case of irritation in the upper respiratory tract, which could be assessed if adequate validated questionnaires were available.
The Panel considers that relief in case of irritation in the upper respiratory tract is a beneficial physiological effect.
1.5. Redukcja dyskomfortu podczas miesiączki (ID 3636)

The claimed effect is “urogenital tract/natural vaginal defence”. The Panel assumes that the target population is the general female population.
From the clarifications provided by Member States, the Panel assumes that the claimed effect refers to defence against vaginal pathogens by increasing the number of lactobacilli and/or decreasing potentially pathogenic bacteria and/or yeasts.
Unlike any other anatomical site of the body, most vaginal vaults are dominated by one or more species of Lactobacillus. In over 70 % of women, vaginal microbiota is dominated by lactobacilli (> 50 %) (Ling et al., 2010; Ravel et al., 2011; Yamamoto et al., 2009). This microbiota is different from the more complex gut microbiota, where lactobacilli represent less than 3 % of the bacterial population (Franks et al., 1998; Lay et al., 2005; Sghir et al., 2000). The diagnosis of bacterial vaginosis (BV) is currently based on Nugent score (microscopic examination of Gram stained smear or vaginal discharge for bacteria and „clue‟ cells). Nugent scores are classified into normal (0-3, lactobacilli are present, but not Gardnerella/Bacteroides or curved Gram-negative bacilli), intermediate (4-6, colonisation by Bacteroides/Gardenella and curved Gram-variable rods (Mobiluncus)), and BV (7-10, BV with domination of Gardnerella/Bacteroides or curved Gram- negative bacilli and absence of that lactobacilli).
The Panel considers that defence against vaginal pathogens by increasing the proportion of lactobacilli and/or decreasing the proportion of potentially pathogenic bacteria and/or yeasts is a beneficial physiological effect.
1.10. Usuwanie metali ciężkich (ID 1871)
The claimed effect is “alginate binds heavy metals, stimulates mucin production and protects the colon, N-acetylcysteine detoxifies and removes heavy metals, piperine increases the bioavailability of n-acetylcysteine”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings and of the references provided, the Panel assumes that the claimed effect refers to the elimination of heavy metals.
The Panel considers that elimination of heavy metals is a beneficial physiological effect.
1.11. Utrzymanie odporności przeciw patogenom w górnych drogach oddechowych, poprzez utrzymywanie prawidłowego stanu układu odpornościowego (ID 1910)
The claimed effect is “immune system”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings and clarifications provided by Member States, the Panel assumes that the claimed effect refers to the maintenance of the upper respiratory tract defence against pathogens by maintaining immune defences.
The Panel considers that maintenance of the upper respiratory tract defence against pathogens by maintaining immune defences is a beneficial physiological effect.

The references provided in relation to these claims were textbooks or narrative reviews which did not provide any original data which could be used for the scientific substantiation of the claim, or reported on animal or in vitro studies which addressed the effects of the food(s)/food constituent(s) on, e.g., spontaneous contractions of the jejunum, adhesion properties of Helicobacter pylori, pharmacologically or stress-induced gastric ulcers, necrotising enterocolitis, intestinal inflammation. One human intervention study which addressed the effects of the food(s)/food constituent(s) on the treatment of Helicobacter pylori infection was also provided. The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claims.
No human studies which investigated the effects of the food(s)/food constituent(s) on measures of gastro-intestinal discomfort were provided in relation to any of the claims evaluated in this section.
The Panel concludes that a cause and effect relationship has not been established between the consumption of the food(s)/food constituent(s) which are the subject of the claims evaluated in this section and reduction of gastro-intestinal discomfort.
