Overview
One type of amino acid is called methionine. Proteins in our bodies are constructed from amino acids, which are the fundamental components of this process. Methionine is an amino acid that can be found in foods such as meat, fish, and dairy products. It contributes significantly to a significant number of the functions that take place inside the body.
In addition to its many other applications, methionine is typically consumed via the oral route when it is used to treat liver diseases and viral infections. However, there is not a lot of study in the scientific community that backs up this usage.
How does it operate?
Methionine is beneficial in cases of acetaminophen intoxication because it stops the breakdown products of the drug from causing damage to the liver. It is also possible that it will function as an antioxidant and assist in protecting damaged tissues.

Uses & Effectiveness
There is some evidence that this treatment can be effective for acetaminophen (Tylenol) intoxication. According to the findings of several studies, administering methionine orally appears to be an effective way to treat acetaminophen intoxication. Treatment needs to start as soon as possible but absolutely has to begin within the first 10 hours after an acetaminophen overdose.
There is not enough evidence to support breast cancer. Consuming a diet rich in methionine may be associated with a reduced likelihood of developing breast cancer.
Cancer of the colon Eating foods that are high in methionine and folate, both of which are different types of B vitamins, may help lessen the risk of developing colon cancer. This appears to be especially true for individuals who have a history of colon cancer in their family as well as individuals who consume a significant amount of alcohol.
Malformations of the neural tube at birth During pregnancy, women who consume a diet higher in methionine appear to have a reduced risk of having a child born with a neural tube abnormality.
Parkinson’s disease. Early study suggests that taking L-methionine by mouth for up to six months can relieve the symptoms of Parkinson’s disease, such as tremors, an inability to control movements, and rigidity.
Flushes of heat. In postmenopausal women, consuming methionine did not appear to reduce the frequency or severity of hot flashes, according to a preliminary study.

Side Effects
When consumed orally in the proportions that are typically present in food, methionine is THOUGHT TO BE SAFE. It is POSSIBLY SAFE when administered intravenously (by IV) or when it is taken orally (by mouth) under the guidance of a trained medical expert. Methionine may bring on symptoms such as headache, heartburn, nausea, diarrhea, dizziness, or sleepiness in certain individuals.
Do not give methionine to oneself as a treatment. If you want to self-medicate, taking methionine orally or administering it intravenously is a choice that MAY NOT BE SAFE. An excess of methionine can be toxic to the brain and could lead to death. Methionine has been shown to raise blood levels of homocysteine, a chemical that has been linked to an increased risk of cardiovascular disease. Additionally, methionine may contribute to the expansion of certain cancers.
Special Precautions and Warnings
When consumed orally in the proportions that are typically present in food, methionine is THOUGHT TO BE SAFE. It is POSSIBLY SAFE when administered intravenously (by IV) or when it is taken orally (by mouth) under the guidance of a trained medical expert. Methionine may bring on symptoms such as headache, heartburn, nausea, diarrhea, dizziness, or sleepiness in certain individuals.

Do not give methionine to oneself as a treatment. If you want to self-medicate, taking methionine orally or administering it intravenously is a choice that MAY NOT BE SAFE. An excess of methionine can be toxic to the brain and could lead to death. Methionine has been shown to raise blood levels of homocysteine, a molecule that has been linked to an increased risk of cardiovascular disease. Additionally, methionine may contribute to the expansion of certain cancers.
When administered orally to children in the amounts that are typically found in food, methionine is likely to be safe for them to consume. It is POSSIBLY SAFE to administer it by IV, but you must do it only under the guidance of a trained medical professional. When administered intravenously to newborns who are simultaneously receiving parenteral nourishment, methionine has the potential to cause serious adverse effects (nutrition through the vein).
When consumed by mouth in proportions that are typically found in food, methionine is considered to be SAFE for use during pregnancy and breastfeeding. However, there is a lack of sufficient knowledge regarding the safety of taking methionine in dosages that are higher than what is typically present in foods. To be on the safe side, you should avoid using it.
People who have a condition known as acidosis should not take methionine because it might induce changes in the blood’s acidity and because it should be avoided in these patients.
Atherosclerosis, often known as “hardening of the arteries,”: There is some evidence to suggest that methionine may accelerate the progression of atherosclerosis. Methionine has the potential to raise blood levels of a chemical known as homocysteine, particularly in people whose bodies are deficient in folate, vitamin B12, or vitamin B6, or in people whose bodies have difficulty processing homocysteine. This is especially true in people who have a history of cardiovascular disease. An elevated level of the amino acid homocysteine is associated with an increased likelihood of developing illnesses in the heart and blood vessels.
Methionine may exacerbate liver disease, particularly cirrhosis, in patients who already have liver disease.
Deficiency of the enzyme methylenetetrahydrofolate reductase (MTHFR): This is a genetic condition that runs in families. It alters the method in which homocysteine is processed by the body. Supplements containing methionine should not be taken by those who have this illness since methionine has the potential to raise levels of homocysteine in these individuals. An elevated homocysteine level may be associated with an increased risk of developing disorders that affect the heart or blood vessels.
Large dosages of methionine, such as 20 grams per day for five days, have the potential to induce psychotic symptoms in patients with schizophrenia. These symptoms include confusion, disorientation, delirium, agitation, and listlessness.
Interactions
At this time, we do not have any information on interactions with METHIONINE.
Dosing
In the course of scientific inquiry, the following doses have been investigated:
ADULTS BY MOUTH:
To treat poisoning caused by acetaminophen (Tylenol), administer 2.5 grams of methionine every four hours for a total of four doses.
