The Claim
In young adult men consuming 0.57 g of egg protein per kg of body weight per day, the addition of 0.23 g/kg/day of nonessential amino acids reduces the energy intake required to maintain nitrogen balance by 10–15%, indicating that total nitrogen availability may limit protein utilization at this protein intake level.
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 young man eating a moderate amount of egg protein, adding some extra nonessential amino acids lets your body stay balanced with less food energy—suggesting that all amino acids together, not just the essential ones, might be holding back how well your body uses protein.

What the research says
1 studyWhen young men ate a moderate amount of egg protein, adding extra amino acids that aren't usually needed from food helped their bodies use protein more efficiently, so they needed less energy to stay healthy. This suggests the body cares about total protein building blocks, not just the ones we must get from food.
