L-aspartic acid

L-aspartic acid is a non-essential amino acid naturally found in the body and in many protein-rich foods such as meat, eggs, legumes, and certain plants. It should not be confused with aspartame, an artificial sweetener that, despite the similarity in name, has no direct chemical relationship with this amino acid. L-aspartic acid plays a central role in cellular energy metabolism, particularly within the Krebs cycle and the urea cycle, two essential metabolic pathways for the proper functioning of the body. It also contributes to the transport of nitrogen between tissues and is involved in the synthesis of other amino acids and nucleotides. Although the body is capable of synthesising L-aspartic acid endogenously, supplementation may be of interest in certain contexts, particularly to support energy metabolism or complement an insufficient dietary intake. It is frequently used in the form of a mineral salt, such as magnesium or zinc aspartate, in order to improve the bioavailability of certain minerals.
