Description
VIP, or vasoactive intestinal peptide, is a 28-amino-acid neuropeptide with wide-ranging roles in the immune, nervous and digestive systems. Limitless Life Nootropics supplies it as a 5mg vial, made in the USA and independently tested.
What Is VIP?
The peptide was discovered in 1970 by Sami Said and Viktor Mutt, who isolated it from pig intestine and noted its ability to dilate blood vessels. It belongs to the secretin/glucagon family and acts on two main receptors, VPAC1 and VPAC2, which are found throughout the body.
Research has explored its roles in smooth muscle relaxation, intestinal secretion, circadian rhythm regulation in the brain’s suprachiasmatic nucleus and the regulation of immune responses, where it is generally studied as an anti-inflammatory signal. It has also been studied in models of lung and autoimmune disease.
Premium lyophilized and Non-Lyophilized grades are both offered at 5mg. The product may contain trehalose as a lyoprotectant.
Key Research Areas
The scientific literature describes this peptide across several areas of investigation:
- VPAC1 and VPAC2 receptor signaling
- Anti-inflammatory immune regulation
- Circadian rhythm in the suprachiasmatic nucleus
- Pulmonary and airway models
- Intestinal secretion and motility
Researchers can review peer-reviewed studies on vasoactive intestinal peptide through the National Library of Medicine (PubMed) database.
