The Claim
In resistance-trained men, a protein intake of up to 3.32 g/kg/day for one year has no adverse effect on serum markers of liver function, including alanine transaminase, aspartate transaminase, and total bilirubin.
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 men who regularly lift weights, consuming up to 3.32 grams of protein per kilogram of body weight daily for one year does not change liver function blood markers such as alanine transaminase, aspartate transaminase, or total bilirubin.
See the scientific wording
In resistance-trained men, protein intake up to 3.32 g/kg/day for one year does not adversely affect serum markers of liver function, including alanine transaminase, aspartate transaminase, and total bilirubin.
The liver processes excess protein by breaking it down into amino acids, using them to build new proteins or convert them into energy, and safely removing waste products without damaging liver cells or altering blood markers of liver health.
What the research says
1 studyMen who lift weights and ate a lot of protein—over 3 grams per kilogram of body weight every day for a year—had no changes in their liver blood tests, meaning their livers stayed healthy.
