COMMISSION REGULATION (EU) 2024/346
of 22 January 2024
amending Annex II to Regulation (EC) No 1333/2008 of the European Parliament and of the Council
and the Annex to Commission Regulation (EU) No 231/2012 as regards the use of trimagnesium
dicitrate in food supplements
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 1333/2008 of the European Parliament and of the Council of 16 December 2008on
food additives(1), and in particular Article 10(3) and Article 14 thereof,
Having regard to Regulation (EC) No 1331/2008 of the European Parliament and of the Council of 16 December 2008
establishing a common authorisation procedure for food additives, food enzymes and food flavourings(2), and in
particular Article 7(5) thereof,
Whereas:
(1) Annex II to Regulation (EC) No 1333/2008 lays down a Union list of food additives approved for use in foods and
their conditions of use.
(2) Commission Regulation (EU) No 231/2012(3) lays down specifications for food additives including colours and
sweeteners that are listed in Annexes II and III to Regulation (EC) No 1333/2008.
(3) The Union lists in Annexes II and III to Regulation (EC) No 1333/2008 may be updated in accordance with the
common procedure referred to in Article 3(1) of Regulation (EC) No 1331/2008, either on the initiative of the
Commission or following an application.
(4) An application for authorisation of the use of trimagnesium dicitrate anhydrous as a stabiliser and anti-caking agent
in food supplements in solid and chewable forms was submitted on 24 June 2015 and was made available to the
Member States.
(5) Trimagnesium dicitrate anhydrous is intended for use in food supplements in solid and chewable forms for binding
small amounts of residual water during processing and inside the packaging.
(6) The European Food Safety Authority (‘the Authority’) evaluated the safety of trimagnesium dicitrate anhydrous(4)
when used as an additive in food supplements in solid and chewable forms and concluded that its use in solid food
supplements at the proposed typical use level of 50 000 mg/kg is of no safety concern, whereas at the proposed
maximum use level of 120 000 mg/kg, the resulting dietary exposure estimate of magnesium for adults and the
elderly for high percentiles would be above the tolerable upper intake level (‘UL’) of 250 mg/day for supplemental
magnesium set by the Scientific Committee on Food, based on a mild, transient laxative effect which is easily
reversible and to which the body can easily adapt within days. Provided that dietary exposure estimates of
magnesium from the use of the food additive trimagnesium dicitrate anhydrous in the food supplement were below
the UL, the Authority considered that there would not be a safety concern from the proposed typical use levels of
trimagnesium dicitrate anhydrous as a stabiliser and anticaking agent in food supplements.

(3) Commission Regulation (EU) No 231/2012 of 9 March 2012 laying down specifications for food additives listed in Annexes II and III
to Regulation (EC) No 1333/2008 of the European Parliament and of the Council (OJ L 83, 22.3.2012, p. 1).

(7) Following the Authority’s opinion, the applicant lowered the requested maximum use levels to 100 000mg/kg so
that the resulting exposure to magnesium in adults and the elderly at the high-level under the instructions of use
provided by the manufacturer for the normal use of the food supplement would not be above the UL authorised as
nutrient in food supplements.
(8) It is, therefore, appropriate to authorise the use of trimagnesium dicitrate anhydrous as a stabiliser and anti-caking
agent in solid food supplements and to assign E 345(i) as E-number to that additive.
(9) The specifications for trimagnesium dicitrate (E 345(i)) should be included in Regulation (EU) No 231/2012 as it is
included in the Union list of food additives laid down in Annex II to Regulation (EC) No 1333/2008 for the first
time.
(10) Regulations (EC) No 1333/2008 and (EU) No 231/2012 should therefore be amended accordingly.
(11) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on
Plants, Animals, Food and Feed,
HAS ADOPTED THIS REGULATION:
