The Claim
In resistance-trained men, consuming post-exercise protein drinks composed of either 100% fast-digested protein or a 50/50 mixture of fast and slow proteins results in greater plasma leucine bioavailability compared to consuming a drink with 20% fast and 80% slow protein.
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 guy who lifts weights, drinking a protein shake after your workout with mostly fast-digesting protein gives your body more of a key muscle-building amino acid—leucine—than a shake with mostly slow-digesting protein.
See the scientific wording
In resistance-trained men, ingestion of post-exercise protein drinks containing 100% fast-digested protein or a 50/50 mix of fast and slow proteins leads to higher plasma leucine bioavailability compared to a drink with 20% fast and 80% slow protein.
What the research says
1 studyThe study found that protein drinks with more fast-digesting protein (like whey) led to higher levels of leucine in the blood after exercise compared to drinks with mostly slow-digesting protein, which matches what the claim says.
