Vasoactive Intestinal Peptide (VIP) is a 28-amino-acid endogenous neuropeptide hormone found throughout the central nervous system, peripheral nerves, immune system, lungs, and gastrointestinal tract. It is a potent regulatory peptide widely distributed in the brain, lungs, immune cells, gut, cardiovascular system. It exerts its effects through cAMP signaling, vasodilation, immune modulation, neuroprotection, and anti-inflammatory cytokine balance. Key cellular actions include suppression of TNF-a, IL-6m IL-12, increases IL-10 (anti-inflammatory cytokine), regulates Th1/Th2/Th17 balance, and protects endothelial and epithelial barriers.

​

BENEFITS

Immune Modulation and Autoimmune Regulation (VIP is one of the strongest endogenous anti-inflammatory peptides)

• Suppresses autoimmune-driven inflammation

• Downregulates overactive macrophages and T-cells

• Promotes immune tolerance

• VIP does not broadly suppress immunity like steroids

​

Pulmonary and Respiratory Benefits (VIP is highly expressed in the lungs)

• Potent bronchodilator

• Reduces pulmonary inflammation

• Improves oxygen diffusion

• Protects alveolar epithelial cells

​

Neurological and Cognitive Effects (acts as a neurotrophic and neuroprotective peptide)

• Enhances cerebral blood flow

• Protects neurons from oxidative stress

• Supports myelin integrity

• Improves circadian rhythm regulation

​

Gastrointestinal and Motility Support (is essential for gut homeostasis)

• Relaxes smooth muscle

• Increases intestinal blood flow

• Enhances mucosal barrier integrity

• Reduces gut inflammation

​

Vascular and Cardiovascular Effects

• Strong vasodilator

• Improves endothelial function

• Reduces platelet aggregation

• Enhances microcirculation

​

Hormonal and Endocrine Effects (interacts with hypothalamic-pituitary signaling)

• Modulates ACTH and cortisol rhythms

• Influences prolactin release

• Support circadian hormone balance

• These effects are part of why VIP is often used in complex chronic illness protocols in late-stage disease

​

Off-Label Use (when used internasally and after inflammatory markers normalize, MARCoNS addressed, and mold/toxin exposure eliminated, VIP may be used for the following)

• Improved cognition

• Reduced fatigue

• Better exercise tolerance

• Improved oxygenation

• Restoration of quality of life

​

ADDITIONAL BENEFITS

• Immune modulation: VIP helps balance immune responses, making it helpful for autoimmune conditions, chronic inflammation, and immune deficiencies

• Respiratory health: VIP can significantly improve lung function and reduce inflammation, which benefits those with asthma or mold-related illnesses

• Brain function and cognition: by promoting blood flow and reducing neuroinflammation, VIP supports cognitive function and may help with brain fog and fatigue

• Gut health: helps regulate gut motility and reduce intestinal inflammation

• Cardiovascular support: it improves circulation by dilating blood vessel

​
