What’s asparagine?

Asparagine is a non-essential amino acid found in various sources, including asparagus, shellfish, poultry, eggs, dairy, whole grains, legumes, soybeans, and nuts. It is produced by the liver and helps fuel the nervous system, maintain emotional balance, and resist fatigue. Deficiency can cause negative symptoms, but can be addressed by addressing the underlying cause of liver malfunction.

Also known simply as Asn, asparagine is a non-essential amino acid found in a number of different sources. First identified in 1806, asparagine is also sometimes known as aspartic acid. The popular name for the amino acid arose due to the discovery of the compound in asparagus juice. Since that time, the amino acid has been identified in a wide range of foods eaten in nearly every culture around the world.

Since then, asparagine has been found in several different animal and plant sources. Some shellfish also contain the amino acid, as do poultry and eggs. Dairy products like milk and cheese also contain small amounts of acid. Even beef is known to contain some amounts of Asn.

Different plants are also sources of asparagine. In addition to asparagus, the acid is found in some root vegetables, such as potatoes. Whole grains like wheat and oats are also excellent sources of the compound, as are some types of legumes and soybeans. Various types of nuts also contain Asn. This intake of acid from natural sources, when combined with the amount of Asn naturally produced in the body, is usually sufficient for the health needs of the individual.

Although it is not considered an essential amino acid, there is no doubt that asparagine has a positive effect on the body. The liver is able to create asparagine for the body and uses it to help fuel the nervous system. The presence of acid helps the system maintain proper emotional balance, sometimes preventing the development of a high degree of sensitivity to touch and sound. At the same time, the amino acid has properties that appear to help the body resist fatigue. This has led to some speculation that the use of asparagine supplements might be useful for athletes, although there is no consensus on this particular application.

When the liver does not produce adequate levels of asparagine, the function of the nervous system is negatively affected. This can manifest as sudden, somewhat painful headaches, a noticeable increase in irritability, forgetfulness, and even the onset of depression. Assuming the liver has not been permanently damaged, it is possible to address the underlying cause of liver malfunction and allow the organ to resume production of sufficient amounts of Asn to alleviate any negative symptoms that occur as a result of the deficiency.
