The Claim
In healthy young adults aged 18–30, consuming 20 grams of a pea-and-canola plant-based protein blend fortified with 1.5 grams of added leucine stimulates muscle protein synthesis to a similar extent as 20 grams of whey protein over a 5-hour period, indicating that leucine content is a key determinant of anabolic response when essential amino acid profiles are balanced.
What the research says
Supports is higher
Support is ahead, but a single strong opposing 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 a plant-based protein shake with extra leucine can build muscle just as well as a whey protein shake, as long as both have the same essential amino acids — the leucine seems to be the secret ingredient.

What the research says
1 studyWhen scientists added extra leucine to a plant-based protein shake, it worked just as well as whey protein at building muscle in young adults — proving that leucine is a big reason why whey works so well.
