When rats swallow a special kind of big molecule labeled with a traceable marker, most of it comes out in their poop within two days — like 9 out of 10 pieces or more.

Claim Language

Language Strength

definitive

Uses definitive language (causes, prevents, cures)

The claim uses 'is primarily excreted' and specifies exact percentages (86.7–95.6%), which convey certainty and precision, indicating a definitive statement about the outcome rather than probability or association.

Context Details

Domain

pharmacology

Population

animal

Subject

radiolabeled high-molecular-weight hyaluronan

Action

is primarily excreted

Target

in feces, with 86.7–95.6% of the radioactivity recovered in feces of rats within 48 hours

Intervention Details

Type: oral administration
Duration: 48 hours

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.

Absorption, uptake and tissue affinity of high-molecular-weight hyaluronan after oral administration in rats and dogs.

Cohort Study

2008 Nov 26

Scientists gave rats a special type of hyaluronic acid by mouth and tracked where it went. Most of it came out in poop, just like the claim says.

Similar Assertions

When rats and dogs swallow a big molecule called hyaluronan, their bodies absorb it and it shows up in places like their joints, spine, and saliva glands—and it stays there for almost two days.

When rats were given a special version of hyaluronic acid by mouth, almost all of it left their bodies within a week through breathing, pee, and poop—very little stayed inside, so it didn’t build up.

When rats were given a special version of hyaluronic acid by mouth, their blood showed the highest level of radioactivity after 8 hours, which means the substance took a long time to get from their stomach into their bloodstream.

When rats were given a special version of hyaluronic acid by mouth, scientists found traces of it in their skin two days and four days later—and even more was in the skin than in the blood, which means the substance traveled through the body and reached the skin.
