The Claim
Whey protein hydrolysate and intact whey protein both increase leucine transport into skeletal muscle and intracellular leucine concentration to a similar extent in healthy young men, but whey protein hydrolysate sustains elevated intracellular leucine levels for up to 3 hours post-ingestion.
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.
In healthy young men, both whey protein hydrolysate and intact whey protein raise leucine levels in skeletal muscle to the same degree, but the hydrolysate form keeps leucine levels elevated for up to three hours after consumption.

When you drink whey protein hydrolysate, it breaks down into tiny pieces that enter your bloodstream faster than whole whey protein. These pieces get pulled into muscle cells more efficiently and keep the leucine levels inside the muscle high for up to three hours. This sustained leucine level keeps the muscle's protein-building machinery active longer than whole whey protein does.
What the research says
1 studyBoth kinds of whey protein get leucine into muscle cells equally well at first, but the broken-down version (hydrolysate) keeps leucine levels high in muscles for up to three hours, while the regular kind only does for one hour.
