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.
When rats were given a special version of hyaluronic acid (a substance found in joints), most of it turned into carbon dioxide and was breathed out within a week, meaning their livers broke it down completely.
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 ate hyaluronic acid, only 16% of it made it into their bloodstream unchanged — the rest got broken down or didn’t get absorbed at all.
