Evidence for inflammation

Each row is an outcome related to inflammation from a published study, strongest design first. Animal and cell results are labelled and are not human results. User reports are not counted as evidence here.

KPV for inflammation: outcomes in published studies
OutcomeResultStudy typeSource
DSS colitis recoveryKPV-treated mice recovered earlier and regained more body weight in DSS colitis.Animal · mouse (not a human result)Inflammatory bowel diseases 2008, PMID 18092346
Survival in MC1R-nonfunctional miceKPV treatment rescued all treated MC1R-nonfunctional mice from death during DSS colitis.Animal · mouse (not a human result)Inflammatory bowel diseases 2008, PMID 18092346
Colitis incidence (oral KPV)Oral KPV in drinking water reduced the incidence of DSS- and TNBS-induced colitis in mice and lowered inflammatory cytokine expression.Animal · mouse (plus human intestinal epithelial and T cell lines) (not a human result)Gastroenterology 2008, PMID 18061177
Peritonitis (neutrophil accumulation)KPV reduced inflammatory cell accumulation in mouse peritonitis through a mechanism distinct from other melanocortin peptides.Animal · mouse (not a human result)The Journal of pharmacology and experimental therapeutics 2003, PMID 12750433
FeverThe tripeptide reduced fever in rabbits after central (0.5-2.0 mg) and peripheral (2-200 mg) administration.Animal · rabbit (not a human result)Peptides 1984, PMID 6333677
Keratinocyte viability and IL-1betaKPV at 50 ug/mL restored cell viability and reduced IL-1beta secretion in PM10-exposed keratinocytes.In vitro (not a human result)Tissue & cell 2025, PMID 40073467
Airway epithelial inflammatory signallingKPV dose-dependently inhibited NF-kB signalling, MMP-9 activity, and IL8 and eotaxin secretion in cultured airway cells.In vitro (not a human result)International journal of physiology, pathophysiology and pharmacology 2012, PMID 22837805

How strong is it?

Strongest evidence:Animal evidence, 2 of 4Inflammatory bowel diseases 2008, PMID 18092346

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.

Common questions

Does KPV help with inflammation?

The strongest study we summarise for inflammation is animal evidence, across 6 studies with an outcome for inflammation. That is not proof it works in people.

Is KPV approved for inflammation?

No. KPV is not FDA approved for any use, including inflammation.

What is the best peptide for inflammation?

There is no single answer. Our inflammation overview compares each candidate by evidence grade and legal status rather than by popularity.
