L-methionine is one of the essential amino acids in humans. It is necessary for the growth of new blood vessels. It has to be obtained through dietary supplements as the human body is not able to manufacture these amino acids by itself.

L - Methionine

Source of L-methionine

As mentioned earlier, it cannot be produced by the human body itself, hence it is essential to take necessary nutrients. These amino acids are found in food that contain proteins.

L-Methionine can be obtained through oral supplements but our daily food usually covers for how much L-Methionine our body needs.

There exists only a slight difference between an animal based and plant based source regarding the concentration of L-methionine present in these products and their availability.

These amino acids are highly soluble. Hence one should avoid overboiling or overcooking of food containing L-methionine. Continuous exposure to these food products may lead to loss of vital nutrients as the structure of the amino acids would be damaged.

Source of L - methionine

Here are a few rich sources for L-Methionine:

  • Turkey
  • Egg Yolk
  • Wild fish
  • Seaweed
  • Plant seeds
  • Sesame seeds
  • Spinach, sprouts
  • Dried soya beans
  • Free-range Chicken
  • Brazil and Cereal nuts

Functions of L-methionine

  • It comprises of oxidant properties and hence it protects the body from toxic radicals and substances.
  • It is necessary for the synthesis of L-Taurine and L-Cysteine.
  • It prevents body cells from being damaged by various foreign particles or substances.
  • These amino acids have an influence on different functions of the body. Example: melatonin, choline, L-Carnitine and adrenaline.
  • L-Carnitine helps in the transportation of long chain fatty acids through the mitochondrial membrane.
  • It is essential for the normal metabolism of the body.
  • It is necessary for acid-base regulation in our body.
  • It has positive effects on the symptoms of allergies.
  • L-methionine regulates the level of histamine in blood. Also, helps in improving bone strength.

Applications of L-Methionine

This sulfurous amino acid would be helpful for people who are suffering from asthma, radiation, drug withdrawal, allergies, depression, Parkinson’s, schizophrenia and copper poisoning. Apart from all these, L-methionine also plays a vital role in acidifying urine. In intravenous drips, it is used as an artificial nutrient.
