L-glutamine is an amino acid that is an essential nutrient supplemented in culture media. It provides a major source of energy for cells grown in culture. In solution, L-glutamine degrades rapidly. L-glutamine is recommended to be supplemented in media just prior to use for optimal performance.

Adding Non-essential Amino Acids to your medium may improve the propagation viability and growth of cells in culture while reducing the burden of biosynthesis on those cells. The concentration of this supplement allows for efficient addition to media without the risk of diluting media components.
