The Claim
In healthy young adults, ingestion of 20 grams of unfortified pea-and-canola plant protein stimulates muscle protein synthesis above fasting levels, but to a significantly lesser extent than whey protein, indicating that natural plant protein blends without leucine supplementation have reduced anabolic potential compared to high-quality animal proteins.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're a healthy young adult, eating 20 grams of plant protein from peas and canola will help your muscles grow a little after fasting, but not as much as drinking whey protein — so animal-based proteins are better at building muscle without added supplements.

What the research says
1 studyThe study found that adding extra leucine to plant protein makes it work as well as whey, but the claim is about plant protein without any added leucine. So this study doesn’t prove the claim — it actually shows the opposite can be true if you fortify the protein.
