L-Methionine

L-Methionine is an essential amino acid, with main functions including:

• Protein synthesis: Involved in the composition of various proteins and peptides, especially sulfur-containing proteins (such as keratin).
• Methyl donor: By generating S-adenosylmethionine (SAMe) to support methylation reactions, it affects the synthesis of DNA, hormones (such as adrenaline), and phospholipids (such as phospholipids).
• Detoxification and antioxidant: promote liver glutathione synthesis, assist in the excretion of heavy metals (such as lead and mercury) and toxins; Its derivative taurine has antioxidant properties.
• Clinical application: Used for liver cirrhosis, depression (regulated by SAMe), and prevention of avian feather growth disorders in animal feed.

Attention: Excessive levels of homocysteine may increase and be associated with cardiovascular risk.
