It is an essential sulfur amino acid that is very abundant in eggs, meat and fish; sesame seeds, Brazil nuts, soybeans, legumes and cereal grains. It is used as an oral dietary supplement and in solutions for parenteral nutrition. It lowers urinary pH and is used in the treatment of urinary tract infections. The use of methionine as an antidote in the treatment of acetaminophen poisoning to prevent hepatotoxicity has been superseded by acetylcysteine. It is metabolised in the liver to ademetionine, and then homocysteine. Oral or intravenous administration.
At the date of the last update, we found no published data on its excretion in breast milk.
Methionine is found in breast milk, but in lower amounts (100 - 200 mg/L) than the other amino acids. (Lawrence 2016, Chavalittamrong 1981)
Authorized use in young infants for parenteral nutrition and treatment of paracetamol poisoning.
The daily requirements of methionine are 15 mg/kg of body weight: 750 to 1,200 mg/day. (FEN 2013, AESAN 2012). At these doses, methionine is compatible with breastfeeding.
High doses of oral methionine can produce elevated plasma homocysteine levels, nausea, vomiting, drowsiness, and irritability, and psychiatric symptoms in vulnerable people. (Martindale, Garlick 2006, Goren 2004)
