KPV: what the research shows
A tiny peptide of three amino acids, studied for calming inflammation in the gut.
Also known as Lys-Pro-Val
At a glance
Not approved. Studied mainly in cells and mice.
What is KPV?
KPV is made of the last three building blocks (lysine, proline and valine) of a natural hormone called alpha-MSH, which helps control inflammation.
How does KPV work?
In lab studies, KPV gets into gut cells through a doorway called PepT1 and quiets the inflammation signals inside them.
What does the research show?
- In a 2008 study, mice with colitis (inflamed bowels) that were given KPV by mouth had less inflammation.
- It hasn’t been tested in proper human trials.
- FDA advisers reviewed it in July 2026 as a possible compounding ingredient for wound healing and inflammation.
Known risks and side effects
- Its effects and safety in people are unknown.
Is KPV approved?
Mostly studied in cells and animals, with little or no proper testing in people.
Not approved. Studied mainly in cells and mice.
