Aspartic acid, one of the two acidic amino acids, plays an important role in metabolism and in the construction of other amino acids and biochemicals. It is a necessary component in creating energy, participating in the citric acid cycle or Kreb's cycle. Its function is integrated with those of other amino acids, and a balance of them is needed to ensure proper metabolic function. Aspartic acid is also essential in forming healthy DNA and RNA, reducing toxins in the liver by expelling ammonia, and producing antibodies. Aspartic acid is one of the non-essential amino ac ids, meaning that the body is capable of producing it. However, adequate production of aspartic acid is dependent on one's overall nutri tional status. It is possible to have a deficiency of aspartic acid, and some people benefit from supplementation.
Aspartic acid has many benefits for the healthy functioning of brain and body. First, it increases energy, because it helps the body generate ATP, the chemical fuel that all cells need. For this reason, it increases stamina and endurance, and may be of some benefit to athletes in his capacity. It is also a vital for maintaining good health, as aspartic acid aids in the production of antibodies. Moreover, a deficiency of aspartic acid may be one of the factors contributing to chronic fatigue syndrome. We also know that people deficient in this amino acid may also suffer from fatigue and depression. In addition, aspartic acid keeps the brain thinking sharply, contributing to brain and neural health. Aspartic acid reduces toxins from the system; in particular, it enables the body to get rid of excess ammonia.
Like many of the other amino acids, aspartic acid is found primarily in concentrated protein sources. It may be obtained from beef, poultry, and dairy products. Sprouting seeds also contain aspartic acid. However, generally speaking, it is difficult to obtain from a vegetarian, especially vegan, diet.
