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)
Scientists gave rats and dogs a type of HA by mouth and tracked it with a harmless radioactive tag—they found the HA showed up in joints, spine, and saliva glands and stayed there for two days, just like the claim says.
