L-methionine may be placed on the market and used as an additive consisting of a preparation. 2. L-methionine may be used via water for drinking. 3. The labelling of the additive and premixtures shall indicate the following: ‘The supplementation with L-methionine, in particular via water for drinking, shall take into account all essential and conditionally essential amino acids in order to avoid imbalances.’ 5.11.2030 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: https://ec.europa.eu/jrc/en/eurl/feed-additives/evaluation-reports
