The Claim
Adding 1.5 grams of leucine to a 20-gram pea-and-canola plant protein blend increases plasma leucine concentration by approximately 42% and muscle protein synthesis by 16% compared to the unfortified blend in young adults, demonstrating that leucine is a limiting amino acid in this plant protein formulation.
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.
Adding a little extra leucine to a plant-based protein shake makes your body absorb more leucine and builds more muscle compared to the shake without it, which means leucine was the missing piece your body needed.

What the research says
1 studyAdding extra leucine to plant-based protein helps your muscles grow better, just like animal proteins do. Without it, plant proteins aren’t as good at building muscle — but adding leucine fixes that.
