Okay yโallโฆ ๐๐คฆ๐ฝโโ๏ธ VIP is one of those peptides where the internet can take a real mechanism and make it sound like a miracle peptide. So I did a little digging because I kept seeing VIP + blood pressure + vasodilation and wanted to separate the actual science from the internet hype. ๐ ๐งฌ What is VIP? VIP = Vasoactive Intestinal Peptide. Itโs a naturally occurring peptide found throughout the nervous system, GI tract, lungs, and cardiovascular system. One of its known actions is vasodilation, meaning it can relax blood vessels and reduce vascular resistance. And yes โ human research has demonstrated that VIP administration can produce significant vasodilation and reductions in blood pressure. โค๏ธ So does VIP lower blood pressure? Potentially, YES. This is where the internet isn't completely wrong. ๐ Research has shown that VIP can: โฌ๏ธ Reduce vascular resistance โฌ๏ธ Lower blood pressure โฌ๏ธ Increase blood flow โฌ๏ธ Increase cardiac output โฌ๏ธ Sometimes increase heart rate There has also been research into VIP and pulmonary vasodilation, including investigations involving pulmonary hypertension. BUTโฆ ๐จ there's an important distinction. Just because VIP can lower blood pressure doesn't mean VIP is an established treatment for everyday hypertension. โ ๏ธ MORE VIP โ AUTOMATICALLY BETTER VIP can have systemic effects, including: โข Lower blood pressure โข Increased heart rate โข Flushing โข Headache โข GI effects โข Increased intestinal secretions โข Potential hypotension And naturally occurring VIP has a very short half-life, which makes formulation, route of administration, stability, and actual peptide quality important considerations. ๐ฌ Where I think VIP gets REALLY interestingโฆ The cardiovascular and pulmonary research is definitely worth watching. There has been legitimate research looking at VIP-related therapies for: โค๏ธ Vascular function ๐ซ Pulmonary vasodilation ๐ซ Pulmonary hypertension ๐ฉธ Vascular resistance ๐ฅ Inflammatory signaling But there is not enough evidence for me to say that research-grade injectable VIP should be used as a DIY treatment for high blood pressure.
