The Claim
In healthy adult men, increasing the dose of whey protein from 0.23 to 0.35 g/kg body mass leads to a dose-dependent increase in both the rate and total systemic availability of dietary protein–derived phenylalanine, with 51% ± 10% bioavailability observed after the lowest dose and 61% ± 7% after the highest dose over a 5-hour postprandial period, indicating a positive causal relationship between whey protein intake and amino acid availability.
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.
When healthy guys drink more whey protein, their bodies absorb more of an important amino acid called phenylalanine—about 10% more when they take a higher dose.
See the scientific wording
In healthy adult men, increasing the dose of whey protein from 0.23 to 0.35 g/kg body mass results in a dose-dependent increase in both the rate and total systemic availability of dietary protein–derived phenylalanine, with 51% ± 10% appearing after the lowest dose and 61% ± 7% after the highest dose over 5 hours, demonstrating a positive causal relationship between whey protein intake and postprandial amino acid availability.
What the research says
1 studyThe study shows that when people eat more whey protein, their bodies absorb more amino acids, including phenylalanine, which supports the idea that higher doses lead to greater availability.
