What this is about

VIP is short for vasoactive intestinal peptide. It is a peptide, a short chain of amino acids.

This is a research summary, not medical advice. It reports what two research reviews say.

What VIP is

A 2019 review describes VIP as a signaling molecule that nerve cells release. It has 28 amino acids. It was first characterized in 1970. Researchers isolated it from a pig's duodenum, the first part of the small intestine. In those tests, it widened blood vessels.

The review places VIP in the brain and in nerves outside the brain. It is also found in the gut, the lungs, and the heart and blood vessels. It acts through two receptors, VPAC1 and VPAC2. Naming a receptor shows where a signal might land. It does not show a result in a person (Iwasaki, Akiba, and Kaunitz, 2019).

What researchers are studying

These findings are from animals, cells, and tissue samples. They are not findings in people.

The 2019 review looks at VIP signals in the gut of animals and in tissue samples.

In mice that cannot make VIP, that review reports a disturbed daily rhythm (Iwasaki, Akiba, and Kaunitz, 2019).

A 2007 review looks at the daily clock in the mammalian brain. That clock sits in a small area called the suprachiasmatic nucleus. VIP marks one group of cells there. Those cells likely use VIP as a signal. In mouse studies, losing VIP or its receptor was linked to disturbed daily rhythms in those cells (Vosko, Schroeder, Loh, and Colwell, 2007). That work is on clock cells. It does not report that VIP helps a person.

What this does not settle

A result in mice, cells, or a tissue sample stays in that test. It does not show that VIP works for a person. This article names no product, seller, or way to use VIP. It does not read a test result.
