What Is L Methionine? What Are The Benefits & Top Food Sources

What Is L Methionine?

Methionine is an amino acid. Amino acids are the building blocks that our bodies use to make proteins.

Methionine is found in meat, fish, and dairy products, and it plays an important role in many cell functions.

Methionine is used to prevent liver damage in acetaminophen (Tylenol) poisoning.

It is also used for increasing the acidity of urine, treating liver disorders, and improving wound healing.

Other uses include treating depression, alcoholism, allergies, asthma, copper poisoning, radiation side effects, schizophrenia, drug withdrawal, and Parkinson’s disease.

How does it work?

In acetaminophen poisoning, methionine prevents the breakdown products of acetaminophen from damaging the liver.

Signs You May Need L-Methionine

The people most likely to have a deficiency of L-methionine are those with a low intake of animal protein such as strict vegetarians.

The most common signs of an L-methionine deficiency include a fatty liver, edema and skin lesions.

Children who don’t receive enough L-methionine in their diet may also have a growth rate that’s below average.

Low L-methionine levels may contribute towards other conditions such as hair loss, low moods and muscle weakness.

Health Benefits of Methionine

Methionine is one of the eight essential amino acids and as an essential amino acid it serves as building block for protein in the body.

Also, an essential amino acid cannot be produced by the body, thus, its supply comes from the food we eat or in supplement pill form.

1. Antioxidant Nutrients

It is a source of sulfur and other compounds required by the body for normal growth and metabolism. Sulfur is very important to life.

Without adequate intake, the body will not be able to make and use a number of antioxidant nutrients. It is also a methyl donor that is needed for a variety of chemical and metabolic reactions in the body.

2. Creatinine

It is essential for the production of creatinine, which is responsible in the proper functioning of muscles and the entire cardiovascular system.

It is also primarily responsible in detoxification and breakdown of fats preventing fat build-up in the liver and arteries. 

3. Metabolism

Methionine has so many functions that aid in normal growth and metabolism.

It comes abundantly from protein-rich foods like meat, poultry, dairy products, fish and other sea foods.

Peanuts roasted with skin and sesame seeds are very rich sources also.

Fruits, vegetables and grains also contain methionine.

However, they contain a lower amount unlike those protein-rich foods. Vegetarians are recommended to take supplements in order to get the required level of this amino acid in the body.

4. Treatment health conditions

It also comes in supplement form and is being used for the treatment of several health conditions like depression, Parkinson’s disease, arthritis, liver cirrhosis, hepatitis, multiple sclerosis, fibromyalgia, chronic fatigue, endometriosis, and others.

5. Increases Your performance

It is also being used by athletes because of its capacity to produce creatinine, the substance that builds strong muscle tissues.

This provides the necessary energy that muscles require to move and increases the performance of athletes during intense workouts.

6. Vitamin B complex

To work best, the intake of methionine should be combined with vitamin B complex to prevent increase of homocysteine and cholesterol levels.

Excessive intake together with deficiency in vitamin B, may cause arteriosclerosis, the hardening of arteries.

L Methionine

Here Are 3 Top Must Include Methionine Rich Foods:

Brazil Nuts

Delicious Brazil nuts are one of the top dietary sources of this particular amino acid. Just one hundred gram serving of tasty Brazil nuts yields almost 1124 mg of methionine.

In short, eating a handful of Brazil nuts helps to meet almost 124 percent of the Recommended Daily Intake or RDI of this powerful amino acid.

Besides Brazil nuts, cashew nuts and pistachio nuts are also excellent sources of this proteinogen amino acid.

Sesame Seeds

Crunchy, nutty flavored sesame seeds are densely packed with nutrients, which includes essential amino acids like tryptophan and methionine.

Consuming a hundred grams of sesame seeds helps to meet almost 34 percent of the RDI of this vital amino acid.

Nutritional studies indicate that this essential amino acid plays a pivotal role in protecting the body from the harmful effects of free radicals.

Sunflower seeds, flax seeds, watermelon seeds and chia seeds are other excellent sources of L-methionine.

Chicken Breast

Chicken breast yields high amounts of this non polar amino acid (925 mg per 100 gms).

In short, a single serving of broiled or roasted chicken breast helps to meet almost 127 percent of the RDI of this amino acid.

The sulphur containing amino acid L- Methionine, which cannot be synthesized by the human body, is essential for normal growth and tissue repair.
