REZA evidence rating B: Reasonable confidence
Methodology
Systematic review with meta-analysis
Findings
In older adults who are not frail and already get enough protein, extra supplementation on its own shows limited effects on fat-free mass, strength and physical function.
Practical conclusion for REZA
This study contradicts the common sales pitch and is included deliberately for that reason: protein powder is not a standard recommendation at REZA. Anyone already getting enough gains little from it.
