VIP (vasoactive intestinal peptide) is a naturally occurring anti-inflammatory neuropeptide studied most notably in Chronic Inflammatory Response Syndrome (CIRS) research following water-damaged-building mold exposure, where VIP levels are commonly found to be depleted.
Benefits
VIP (vasoactive intestinal peptide) has real human trial data, primarily through the synthetic formulation aviptadil, which the FDA has granted orphan-drug status for several respiratory conditions.
Phase II trial, sarcoidosis (n=20, nebulized/inhaled, 4 weeks): safe and well-tolerated, significantly reduced TNF-alpha production from lung immune cells, and increased regulatory T-cells — described as the first human demonstration of VIP's immunoregulatory effect in lung inflammation. Prasse et al., Am J Respir Crit Care Med, 2010 VIP/aviptadil has also been studied for pulmonary arterial hypertension and, more recently, critical COVID-19 respiratory failure via IV administration.
Dosage
The sarcoidosis trial used nebulized/inhaled delivery over 4 weeks — a different route than the subcutaneous injection format typically sold as a research peptide. Worth confirming the actual delivery route of the product before assuming the inhaled-trial data translates directly.
What is VIP researched for?+
Anti-inflammatory and immune-modulation research, most notably in the context of Chronic Inflammatory Response Syndrome (CIRS) linked to mold/water-damaged-building exposure.
Is VIP FDA-approved?+
No, it is not an approved drug product for CIRS or general use and is sold for research use only.
What are commonly reported effects when using VIP?+
Transient headache, dizziness, and palpitations are commonly reported in the research literature and are generally described as short-lived.
Is VIP just for gut issues, or does it do more?+
Much more — it's a genuine multi-system signaling peptide, involved in blood vessel dilation, immune regulation, nerve protection, and even circadian rhythm control, not just digestion despite the name.
Does it actually calm mast cells / help with MCAS?+
Yes, real mechanistic backing — VIP has been shown to significantly inhibit mast cell activation and block the release of histamine and other inflammatory mediators, part of why it comes up specifically for mast cell activation syndrome.
