PDCAAS Calculator

Calculate the Protein Digestibility-Corrected Amino Acid Score.

PDCAAS Components

Amino Acid Score (%)

Based on limiting essential amino acid vs reference pattern

True Digestibility (%)

Typical: Egg 97%, Meat 92%, Beans 78%

Protein Amount (grams)

PDCAAS = (Amino Acid Score x Digestibility) / 100

Maximum value is truncated at 1.0 (100%)
