L-aspartic acid has a variety of physiological functions and effects in the human body. First of all, it participates in protein synthesis and nitrogen metabolism processes and is one of the important components for building proteins. Secondly, L-aspartic acid is also involved in the synthesis of neurotransmitters and plays an important role in the normal function of the nervous system. In addition, L-aspartic acid is also involved in physiological processes such as immune regulation and cell signaling.

L-aspartic acid is widely found in foods, such as meat, fish, poultry, eggs, dairy products, beans, etc. Additionally, L-aspartic acid can also be taken through dietary supplements. However, under normal circumstances, the body’s demand for L-aspartic acid can be met through normal dietary intake and does not require additional supplementation.
