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.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'indicating' to suggest an inference or interpretation rather than a direct causal link. 'Peaked' is a factual observation, but 'indicating' introduces a probabilistic interpretation of the data, implying likelihood rather than certainty.

Dietary Hyaluronic Acid Migrates into the Skin of Rats
Scientists gave rats a special glowing version of hyaluronic acid to swallow and found the glow in their blood peaked after 8 hours, meaning it took a while to get absorbed — just like the claim says.
