What is L-methionine

L-Methionine is an essential amino acid that plays a key role in protein synthesis and various metabolic processes,
making it an important nutrient in animal nutrition.
In poultry, it is considered the first limiting amino acid and must be supplied through feed,
as plant-based protein sources are deficient in methionine.
L-methionine not only serves as a constituent of skeletal muscle protein but also optimizes
the development of the digestive tract and growth performance.
Its physiological functions include antioxidant effects, heat stress reduction, fatty liver inhibition,
and liver detoxification through metabolic products such as glutathione.

L-Methionine VS DL-Methionine

DL-Met is produced by synthetic process, while L-Met is produced by fermentation process.
L-Met is a key in utilization for intestinal development and digestive tract due to the
higher bioavailability than DL-Met. DL-Met must be converted to L-Met to mobilize in the body.
