Without prejudice to Directive 2002/46/EC, L-ergothioneine as specified in Annex I may be placed on the Union market as a novel food ingredient to be used in food supplements intended for the general population, excluding infants and young children, and pregnant and lactating women, for the uses defined and at the maximum levels established in Annex II.
The designation of L-ergothioneine authorised by this Decision on the labelling of the foodstuffs shall be ‘L-ergothioneine’.
This Decision is addressed to Tetrahedron, 14, avenue de l'Opéra, 75001 Paris, France.
