What is Methionine

Methionine is a proteinogenic amino acid. It is scientifically classified under essential amino acids which form the body’s main building blocks that facilitate the synthesis of proteins, but it cannot be produced naturally by the body. This means that Methionine should be sufficiently supplied to the body through our daily diet or dietary additives such as vitamin supplements. Methionine can be obtained from fish, meat and a variety of dairy products. It is the only sulfur-containing amino acid and its role in the synthesis of proteins makes it one of the most valuable essential amino acids. Methionine is a vital component in the MIC injections abbreviated as “M” in MIC. It is also used in many other Lipotropic injections in different combinations.

Uses of Methionine

Methionine can be used to prevent the damage of the liver in a case of Acetaminophen/Tylenol poisoning. It can also be used to increase the acidity of urine, to treat liver disorders and to fasten/improve the healing of wounds. Other uses of methionine include; treating alcoholism, suppressing psychological problems like depression and alleviating allergies. It can be used to treat asthma, copper poisoning, and the side effects of radiation, drug withdrawal, schizophrenia and Parkinson’s disease.
Methionine is a very powerful antioxidant because it contains Sulfur. Sulfur helps to neutralize free radicals that are formed due to numerous metabolic processes in the body. The deficiency of Methionine has negative effects on the body’s serum levels because sulfur-containing amino acids increase the vulnerability of fats and lipids to degenerate and metabolize. This deficiency can play a role in the development of heart diseases. Methionine also facilitates the proper functioning of the immune system and it can help to treat UTI’s by preventing the destruction of the bladder by bacteria.
There are multiple suggestions that methionine can be used to treat some conditions and to help manage others but there is still insufficient evidence to prove these claims. Some of these conditions include; cobalamin deficiency, neural tube birth defects, liver functioning, depression, alcoholism, allergies, asthma, side effects of radiation, drug withdrawal and their associated conditions.
