KPV

Also known as: KPV Tripeptide, Alpha-MSH Fragment 11-13, Lysine-Proline-Valine

KPV is a tripeptide (Lys-Pro-Val) derived from the C-terminal sequence of alpha-melanocyte-stimulating hormone (alpha-MSH), an endogenous neuropeptide with broad anti-inflammatory activity. Despite being a very small fragment, KPV retains the anti-inflammatory signaling capacity of the parent molecule. It inhibits NF-kB activation and reduces the production of pro-inflammatory cytokines including TNF-alpha, IL-6, and IL-1beta. Research has demonstrated its efficacy in models of inflammatory bowel disease, where it reduces colonic inflammation when administered orally. KPV also exhibits antimicrobial properties against certain bacteria, making it a dual-function peptide for gut and immune health.

Dr. Taylor's 2 Cents

“KPV is a powerhouse anti-inflammatory that I use extensively for gut health. It's a tiny tripeptide derived from alpha-MSH, but it packs a serious punch against NF-kB-driven inflammation. The IBD research is particularly promising. I use it orally for gut-specific inflammation and subcutaneously for systemic inflammatory conditions. It's one of the best-tolerated peptides I prescribe.”
