Giving mice a specific type of hyaluronic acid pill every day for a week doesn't make more of it show up in their blood or body tissues compared to mice that just got water.

definitive
Uses definitive language (causes, prevents, cures)

Subject
Oral administration of very low molecular weight hyaluronic acid (5 kDa) at a dose of 100 mg/kg/day for 7 days
Action
does not show
Target
a statistically significant increase in hyaluronic acid levels in plasma or tissues of adult female C57BL/6J mice compared to saline control

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 (0)
Contradicting (1)
Steady state plasma and tissue distribution of low molecular weight hyaluronic acid after oral administration in mice
The study gave mice a small dose of this substance and found it did raise levels in their blood and tissues — but the claim says it doesn’t. So the study proves the claim wrong.
