Methionine
Methionine is essential for the production of taurine - an amino acid that is important for heart function and nerve transmission. Deficiency of methionine interferes with the production of phospholipids that are important for the nervous system and for preventing blood stickiness.
Methionine, cysteine, and cystine are all sulphur containing amino acids. Methionine can break down fats and is a powerful antioxidant and also protects the body from toxic substances. Combined with folic acid choline, it protects against some cancers.
It has been used to treat paracetamol overdose, and to remove heavy metals from the body.
Methionine composes 25% of collagen - necessary to give structure to the skin.
Legumes are short of methionine, so vegetarians get their mehtionine from cereals. Beens, beef, milk, and eggs have sufficient mehtionine.
