Milk powders vs. other proteins

Milk powders deliver a superior source of complete protein, outperforming many other common foods on the PDCAAS ranking, an industry standard for measuring protein quality.

What is PDCAAS?

PDCAAS, or Protein Digestibility Corrected Amino Acid Score, is a scientific method for rating the quality of dietary proteins based on both essential amino acid content and digestibility. A top score of 1.0 confirms a protein provides all essential amino acids in highly digestible form.

Comparing Popular Proteins

Milk protein (whey/casein): 1.0 (perfect score for quality and digestibility)

Egg protein: 1.0 (matches milk, also a gold standard)

Chicken: 0.95 (excellent, only slightly lower than milk and egg)

Beef: 0.92 (very good quality, but not perfect)

Almonds: 0.4 (reflecting incomplete amino acid profile and digestibility challenges)

Why Milk Powders Stand Out

Milk powders, using either whey or casein, have the highest possible PDCAAS score, making them a trusted source for complete protein in nutrition formulas, active lifestyles, and everyday diets. Their perfect score shows why milk proteins are often featured in premium blends and scientific nutrition solutions.
