Methionine Benefits: 3 Secret Uses

By Jayton Miller

Methionine is an amino acid that plays a necessary role in the body, however, it can be eaten in excess and cause some problems with a few other amino acids. Let’s take a look at what methionine can do…


What Is Methionine?:

What Is Methionine


Methionine is an essential amino acid. This means that our bodies lack the ability to properly make this amino in quantities high enough to support bodily functions. This means that we must get this protein from external or exogenous sources. Methionine is one such amino acid that is rather high in muscle meats. It is used to help make the non-essential amino acid cysteine (among other important molecules).

Benefits Of Methionine:

Benefits Of Methionine

Extreme methionine deficiency can be disastrous for some people. In these cases getting your levels up to the lower end of normal could potentially lead to the following benefits. 

Methionine May Help Boost Glutathione

One of the limiting factors in glutathione synthesis is methionine availability. Meaning that the more methionine available from the diet, the higher the glutathione levels tended to be. However, it is important to note that the evidence that supports this is mostly in vitro (in single cells within the glass) and the in vivo (within the animal) studies have actually shown the opposite happening

Methionine Can Help Increase Taurine Levels

Methionine can be converted into cysteine and then taurine. Taurine is an amino acid that can have a myriad of benefits. From helping to support healthy nerve growth, to improving sports performance. A reason that it is usually added to many different sports drinks. 

Methionine Could Help Support DNA Methylation

Methionine has the ability to convert into S-adenosylmethionine, or “SAMe.” This compound acts as a methyl donor to DNA allowing for methylation of DNA to take place. This can result in both favorable and unfavorable effects depending on the environmental factors that are present.

How To Use Methionine


Although beneficial, it might not be a great idea to start taking in copious amounts of methionine. It might be in your best interest to take steps to start lowering your methionine intake. As your methionine intake may already be too high. Lower methionine diets have been shown to increase lifespan in animalsimprove glutathione concentrations, and help to lower overactive inflammatory pathways that could lead to premature aging.

Foods That Contain Methionine:

Foods That Contain Methionine


Methionine can be found in many different food sources. Some of the best sources of methionine are:

  • Eggs
  • Fish
  • Dairy products
  • Beef
  • Chicken

Almost all foods that contain protein are going to have some methionine in them. The ones above are the most notable.
