Bacteria in the gut break down a substance called hyaluronan into tiny pieces, and some of those tiny pieces get absorbed through the gut wall in mice.

definitive
Uses definitive language (causes, prevents, cures)
The verb 'cleave' is a definitive action term indicating a direct biochemical process, and 'are partially absorbed' states a concrete physiological outcome without hedging, suggesting certainty in the mechanism and result.

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 found that good bacteria in mice’s guts break down hyaluronic acid into tiny pieces smaller than 3 kDa, and some of those pieces get absorbed through the gut wall — just like the claim says.
