  • Vitamins and minerals to fortify the powder

Understanding these additives is important for consumers with allergies or dietary restrictions.

Protein Quality and Amino Acid Profile Considerations

Protein quality in vegan powders is often assessed based on amino acid completeness and digestibility. Since most plant proteins lack one or more essential amino acids, manufacturers often blend multiple sources to create a balanced profile. For example, combining pea protein (rich in lysine) with brown rice protein (higher in methionine) yields a more complete amino acid profile.

Key factors influencing protein quality include:

  • Digestible Indispensable Amino Acid Score (DIAAS): A modern metric assessing digestibility and essential amino acid content.
  • Biological Value (BV): Indicates how well the protein supports body protein synthesis.
  • Protein Efficiency Ratio (PER): Measures weight gain relative to protein intake in animal studies.

Most high-quality vegan protein powders aim for a DIAAS comparable to animal
