Introduction to VIP
VIP (Vasoactive Intestinal Peptide) is a 28-amino acid neuropeptide naturally produced in the body. It is found in the brain, gut, lungs, and immune system. Researchers study VIP for its strong anti-inflammatory, immune-balancing, and neuroprotective effects.
This peptide is gaining interest in studies involving chronic inflammation, autoimmune conditions, lung health, and gut-brain axis research.
How VIP Works
VIP binds to VPAC1 and VPAC2 receptors throughout the body. This binding reduces pro-inflammatory cytokines (such as TNF-α, IL-6, and IL-1) while increasing anti-inflammatory signals. It also acts as a vasodilator, supports tissue repair, and helps regulate communication between the nervous system and immune system.
Key Research-Backed Benefits of VIP
Powerful Anti-Inflammatory Effects
Helps reduce chronic inflammation in conditions like arthritis, IBD, and autoimmune disorders.
Immune System Balance
Modulates immune responses and promotes resolution of excessive inflammation.
Neuroprotective Properties
Protects brain cells and shows promise in neurodegenerative disease research.
Lung and Cardiovascular Support
Studied for improving blood flow, reducing pulmonary hypertension, and supporting respiratory health.
Gut Health Research
Helps regulate intestinal function and reduce gut inflammation.
Tissue Repair and Wound Healing
Promotes new blood vessel formation and tissue remodeling.
Potential in Sarcoidosis
Explored for reducing inflammation in chronic lung and systemic conditions.
VIP Research Dosage Protocols
Important: The following information comes from published research and is for laboratory and in vitro use only.
-
General Anti-Inflammatory Research: 50–200 mcg per day, often split into multiple doses.
-
Pulmonary / Inhalation Studies: Up to 200 mcg daily, sometimes divided into 4 doses.
-
Systemic Research: 0.2–0.4 mg daily via subcutaneous injection.
-
Administration: Subcutaneous injection or nasal/inhaled delivery depending on the study focus.
-
Cycle Structure: Common protocols run 4–12 weeks, followed by a break period.
-
Reconstitution: Mix with bacteriostatic water (example: 5 mg vial + 5 mL water = 1 mg/mL). Store refrigerated and protect from light.
Why Researchers Study VIP
VIP stands out because it combines strong anti-inflammatory action with immune regulation and neuroprotective benefits. It is especially useful for studying complex conditions involving chronic inflammation and the gut-brain connection.
