When mice eat certain types of hyaluronan, their bodies break down the parts they can’t absorb directly into tiny fatty acids, and those fatty acids are the only things their bodies can actually use from this substance.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses the definitive verb 'are metabolized into' and 'are the only metabolites', which assert a certain and exclusive outcome without hedging, indicating a definitive causal mechanism.

Subject
The remaining hyaluronan fragments not absorbed as oligosaccharides
Action
are metabolized into
Target
short-chain fatty acids, which are the only metabolites available to the host in mice

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.
Evidence from Studies
Supporting (1)
Molecular weight and gut microbiota determine the bioavailability of orally administered hyaluronic acid.
The study gave mice hyaluronan to eat and found that whatever wasn’t absorbed directly got turned into short-chain fatty acids—and nothing else. That’s exactly what the claim says.
