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 special type of hyaluronic acid with a radioactive tag, and found it showed up in their skin, bones, and joints a day later — but a similar radioactive chemical without the hyaluronic acid didn’t. So yes, the hyaluronic acid gets absorbed and goes where the claim says.
