Why an oral peptide is not a contradiction for KPV

Most peptides are useless taken by mouth: the gut digests them. KPV is unusual because it can ride a real transporter, PepT1, that actively pulls dipeptides and tripeptides into intestinal cells. That single fact is the backbone of KPV's gut-health reputation.

This unit explains how PepT1 works, why it is preserved in inflamed gut exactly where you want it, and the crucial distinction between local gut exposure and whole-body bioavailability.

Key terms

The transporter that makes oral plausible


Active transport beats passive diffusion


The transporter survives where it is needed


Not just epithelium


Local exposure is not the same as bioavailability
