When mice eat hyaluronan, it’s probably not the whole molecule that helps their skin and joints—it’s the smaller pieces it breaks down into that do the work.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'likely due to', which expresses likelihood rather than certainty, placing it in the probability category. It avoids definitive language like 'causes' or 'proves', and instead suggests a probable explanation.

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.
When mice eat hyaluronan, their gut bacteria break it into tiny pieces, and those pieces — not the original stuff — get into their bloodstream and help their skin and joints. So the benefits come from the broken-down bits, not the big molecule.
