Net Protein Utilization (NPU) is a measure of the efficiency with which the body can use dietary protein, calculated as the ratio of amino acids converted into proteins to the total amino acids consumed. It reflects both the digestibility of the protein and the biological value, indicating how well the absorbed protein can be utilized for growth and maintenance in the body.

Net Protein Utilization

Dietary protein is essential for building and repairing tissues, and it plays a crucial role in the structure, function, and regulation of the body's cells, organs, and systems. Adequate protein intake is vital for maintaining muscle mass, supporting immune function, and optimizing overall health and well-being.

Biological Value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It provides a way to evaluate the quality of a protein source based on its amino acid composition and digestibility.
