The Claim
In healthy adult men, increasing the dose of casein protein from 0.24 to 0.44 g/kg body mass increases the absolute amount of dietary protein–derived amino acids appearing in the circulation over a 5-hour period, from 9.4 ± 2.4 g to 13.0 ± 3.6 g, while reducing the relative fraction absorbed from 47% ± 12% to 41% ± 11%, indicating that higher casein doses enhance total amino acid delivery despite lower proportional absorption, likely due to incomplete digestion within the measurement window.
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 healthy guys drink more casein protein, more amino acids show up in their blood overall—even though a smaller percentage gets absorbed—probably because their bodies haven’t finished digesting it within 5 hours.

What the research says
1 studyThe study shows that eating more casein protein leads to more amino acids in the blood overall, even though the body absorbs a slightly smaller percentage of it, which matches what the claim says.
