Yes, brüst uses the cleanest and highest quality proteins. The standard for measuring the quality of a protein in a food or drink is called the Protein Digestibility Corrected Amino Acid Score (PDCAAS). The quality of the whole food protein is based on the food’s essential amino acid content, based on human needs, and its digestibility (ability to supply amino acids). brüst contains a 1.0, the highest PDCAAS score a food protein can receive. This means that brüst’s food protein contains 100% of the amino acids in the right amounts needed by the body.
