What is KPV?
KPV is an oral peptide derived from alpha MSH (Melanocyte Stimulating Hormone) that acts potently on immune-mediated inflammatory conditions such as dermatitis, bowel diseases, allergic asthma, and arthritis by inactivating pro-inflammatory pathways.
It is found naturally in the body as a breakdown product of aMSH.
- Improves Gut Health
- Mast Cell Stabilisation / Reduces histamine
- Assists post toxic-mould exposure
- Anti Inflammatory
- Anti Microbial
- Wound Healing
- Skin Healing
- Protect against Nerve Damage
- Strengthen Immune System
In a mice model of colitis (colon inflammation), oral administration of KPV (added to drinking water) inhibited the activation of NF-κB and MAP kinase inflammatory signalling pathways and reduced pro-inflammatory cytokine secretion.
