What is L-Asparagine?
L-Asparagine is a non-essential amino acid that can be synthesized by the human body but can also be obtained through food or supplements. It is a crucial component of protein, and the importance of protein in the human body is self-evident.
Benefits of L-Asparagine
- L-Asparagine promotes protein synthesis (repair of skin, cells, and bones; enhances immunity; provides energy), and accelerates nitrogen metabolism (regulates respiratory function; assists in urea excretion; aids cell repair).
- In a series of animal studies, L-Asparagine has antitussive and antiasthmatic effects.
- L-Asparagine can be obtained in a variety of ways. It is found in most meats, such as beef, poultry, and eggs, and can also be supplemented through commercial health supplements.
If you have any questions about processing L-Asparagine, Highassay’s R&D team is here to help.

L-Asparagine Anhydrous VS L-Asparagine Monohydrate
L-Asparagine monohydrate has an additional water molecule in its chemical formula compared to L-Asparagine anhydrous, resulting in differences in its properties and usage scenarios. We recommend purchasing L-Asparagine based on your needs, whether it contains water or not.
