It is an important feed additive, which can balance the amino acid composition of feed and enhance the nutritional value of feed; it can also boost the immunity of animals; for some liver diseases such as fatty liver and liver cirrhosis, supplementing methionine can provide methyl groups, promoting the detoxification function and fat metabolism of the liver; after liver damage, an appropriate supply of methionine can provide raw materials for the repair of liver cells and accelerate the recovery of liver function; it can also be used as a component of certain drugs to treat some diseases caused by abnormal methylation metabolism.
