New Roots L-Methionine. L-Methionine is one of the essential sulphur amino acids. Called a "methyl donor", L-Methionine contributes to the formation of numerous important compounds in your body. This process is called "methylation". Deficient "methylation" is implicated in cases of depression.
The body cannot produce L-Methionine. It must be obtained from food or supplement sources. Methionine functions as a sulphur donor to aid in your body`s detoxification processes and can convert to other sulphur amino acids. L-Methionine is also a transporter of the antioxidant mineral selenium.
In addition to its role as a precursor in protein synthesis, L-Methionine participates in a wide range of biochemical reactions, including the production of S-adenosylmethionine (SAMe), L-cysteine, glutathione, taurine and sulfates. SAMe itself, as a methyl donor is involved in the synthesis of creatine, epinephrine, melatonin and the polyamines, spermine and spermidine, among several other substances.
Each Capsule Contains:
L-Methionine (DL-Methionine) - 500mg
As a dietary supplement, take 1 capsule 1 to 2 times daily with food or as directed by your health care practitioner.
L-Methionine is classified as an essential amino acid for humans and therefore must be supplied in the diet. According to the Food and Agriculture Organisation of the United Nations (FAO) and World Health Organisation (WHO), recommended daily L-Methionine intake is 13 mg per kg or about one gram daily for adults. This is principally derived from dietary proteins. Rich sources of L- Methionine include cheeses, eggs, fish, meat and poultry. L-Methionine is also found in fruits and vegetables, but not as abundantly. Small amounts of free L-Methionine occur in vegetables, vegetable juices and fermented foods. Sunflower seeds are an excellent source of methionine while soy is very deficient. Diets deficient in L-Methionine may result in destructive breakdown and metabolism of protein. L-Methionine is also a glycogenic amino acid and may participate in the formation of D-glucose and glycogen. The ability of L-Methionine to reduce the liver- toxic effects of such hepatotoxins as acetaminophen and methotrexate has led to the suggestion that L-Methionine should be added to acetaminophen products. Methionine plays a key role in regulating the availability of folic acid. L-Methionine deficiency makes folic acid unusable and may induce a build up of the unusable folic acid.
There is a tendency for allergic (high histamine) persons to be L-Methionine deficient. They may respond favorably to L-Methionine, because it lowers blood histamine levels.
