DIAAS

The Digestible Indispensable Amino Acid Score is a more recent protein-quality metric that measures true digestibility of each essential amino acid and, unlike PDCAAS, is not capped at 1.0 — so some high-quality proteins score above 100%. It is considered more accurate but is published far less often. When a brand cites DIAAS we report it; when it does not, PDCAAS or the raw amino profile does the work. Either way it is a factual quality measure, not a claim about results.
