Some types of protein building blocks (amino acids) make more ammonia than others when broken down — especially in people with liver problems.

Assessment Explanation

The abstract uses 'have the potential to generate' — appropriately cautious language for a narrative review summarizing prior biochemical data. No causal claims are made.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Narrative Review

2022 Jul 15

This study looks at which amino acids (building blocks of protein) make more ammonia in people with liver disease, and finds that some do—so yes, some amino acids are worse than others at causing ammonia buildup.

People with severe liver disease need lots of protein to stay healthy, but eating protein can make their brain symptoms worse — so doctors don’t know what to recommend.

When the liver can't clean out ammonia properly, it builds up in the blood and messes with brain function, causing confusion or drowsiness.
