The Claim

Animal proteins exhibit significantly higher digestibility and bioavailability compared to plant proteins, as assessed by the Digestible Indispensable Amino Acid Score (DIAAS) or comparable methodologies.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Animal proteins are easier for your body to break down and use than plant proteins, according to scientific scoring methods.

See the scientific wording

Animal proteins have significantly higher digestibility and bioavailability compared to plant proteins, as measured by DIAAS (or similar) scoring methods.

Why this might work

Animal proteins are easier for your body to break down and use because they have a complete set of essential amino acids and lack anti-nutrients that block digestion. This leads to more amino acids being absorbed into your blood.

What the research says

1 study
  1. Study: Evaluation of the nutritional quality of yeast protein in comparison to animal and plant proteins using growing rats and INFOGEST model.

    This study shows that animal protein (whey) scores better on the digestibility scale than plant proteins, supporting the idea that animal proteins are easier for your body to use.
