Aspartic acid, also known as L-aspartate, is a non-essential amino acid, which is used to promote a robust metabolism. Aspartic acid plays a role in the citric acid cycle, or Krebs cycle, during which other amino acids and biochemicals, such as asparagine, arginine, lysine, methionine, threonine, and isoleucine, are synthesized.
Aspartic acid is used as a treatment for chronic fatigue due to the role it plays in generating cellular energy. Aspartic acid moves the coenzyme nicotinamide adenine dinucleotide (NADH) molecules from the main body of the cell to its mitochondria, where it is used to generate adenosine triphosphate (ATP); the fuel that powers cellular activity.
Aspartic acid helps transport minerals needed to form healthy RNA and DNA to the cells, and strengthens the immune system by promoting increased production of immunoglobulins and antibodies (immune system proteins). Aspartic acid increases NADH in the brain and removes excess toxins from the cells.
