What the studies can tell you.

No studies in people were found

By September 28, 2026, FDA, the US medicine regulator, had found no studies giving KPV to people. [a]

FDA also found no records of human use by mouth, on the skin or by any other route. [a]

“Human cells” in a paper does not mean human patients. Look for what the researchers actually worked with.

The bowel results came from mice

In published mouse studies, KPV reduced bowel inflammation caused on purpose in the lab. [b]

Inflammation is the body’s response to harm or irritation. In these studies, the bowel problem was created as part of the experiment.

Those mouse results do not show that KPV treats bowel disease in people. [b]

When an offer says “gut health,” ask: “Did the experiment test people, or were mice the only subjects?”

Cells in a dish are not patients

In human cells grown in a dish, KPV reduced chemical messages that help trigger inflammation. [b]

FDA says researchers still do not know exactly what KPV acts on in the body to cause these effects. [a]

A cell experiment can suggest what to study next. It does not tell us what happens when a person receives KPV.

The skin study used donated samples

In a lab study of donated human skin, KPV did not pass through intact skin in amounts the test could measure. [c]

That experiment was not a test of KPV treatment in living people. [c]

Ask whether an offer is using this donated-skin result to make a claim about treating living people.
