VIP Dosing Protocol: Vasoactive Intestinal Guide
Also known as: Vasoactive Intestinal Peptide
What is a Peptide?
A short chain of amino acids (2-50) linked by peptide bonds. Smaller than proteins. Your body produces thousands of peptides naturally as signaling molecules that regulate everything from appetite to healing. Therapeutic peptides mimic or enhance these natural signals.

Overview
VIP is a 28-amino acid neuropeptide with wide-ranging effects on immune function, circulation, and brain health. Used in research for mold illness (CIRS), autoimmune conditions, and neuroprotection.
Mechanisms of Action
- Activates VPAC1 and VPAC2 receptors modulating immune responses
- Reduces pro-inflammatory cytokine production (TNF-α, IL-6)
- Promotes regulatory T-cell function and immune tolerance
- Vasodilation and improved blood flow
