EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA); Scientific Opinion on the substantiation of health claims related to a combination of Lactobacillus helveticus CNCM I-1722 and Bifidobacterium longum subsp. Longum CNCM I-3470 and alleviation of psychological stress (ID 938) and “maintains the balance of healthy microbiota that helps to strengthen the natural defence” (ID 2942) (further assessment) pursuant to Article 13(1) of Regulation (EC) No 1924/2006

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to provide a scientific opinion on health claims pursuant to Article 13 of Regulation (EC) No 1924/2006 in the framework of further assessment related to a combination of Lactobacillus helveticus CNCM I-1722 and Bifidobacterium longum subsp. longum CNCM I-3470 and alleviation of psychological stress and “maintains the balance of healthy microbiota that helps to strengthen the natural defence”.

The food constituent that is the subject of the health claims, a combination of L. helveticus CNCM I-1722 and B. longum subsp. longum CNCM I-3470, is sufficiently characterised. The claimed effect, alleviation of psychological stress, is a beneficial physiological effect. No human intervention studies were provided from which conclusions could be drawn for the scientific substantiation of the claim.

On the basis of the data provided, the Panel concludes that a cause and effect relationship has not been established between the consumption of a combination of L. helveticus CNCM I-1722 and B. longum subsp. longum CNCM I-3470 and alleviation of psychological stress. From the information provided for the claimed effect “maintains the balance of healthy microbiota that helps to strengthen the natural defence” it was not possible to establish the specific effect which is the subject of the claim.

The Panel considers that the claimed effect is general and non-specific, and does not refer to any specific health claim as required by Regulation (EC) No 1924/2006.
