The Claim
Splanchnic sequestration increases with age, resulting in a reduced proportion of dietary protein reaching skeletal muscle.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
As people age, more dietary protein is retained in the abdominal organs instead of being delivered to skeletal muscle.
See the scientific wording
Splanchnic sequestration increases with age, reducing the proportion of dietary protein that reaches skeletal muscle.
As people age, the liver and intestines pull more amino acids out of the blood after a meal, leaving fewer amino acids available to reach muscles. This happens because the organs use more amino acids for their own needs, like making proteins and energy, and they absorb amino acids more efficiently. Less amino acid reaches the muscles, so muscle building slows down.
What the research says
1 studyStudy: Dietary protein splanchnic uptake and digestibility via stable isotope tracers
As people get older, their belly organs (like the liver and intestines) hold onto more of the protein from food instead of letting it go to muscles. The study found this happens more with age, which matches the claim.
