What is IRW?
A naturally occurring egg-derived tripeptide reported to inhibit ACE and improve vascular function in preclinical hypertension models. It is one of the better-studied food peptides for blood-pressure support.
Key Benefits & Mechanisms
ACE inhibition
renin-angiotensin system
endothelial protection
Research Summary
Derived from ovotransferrin/egg proteins and shown in experimental studies to lower blood pressure and support endothelial nitric-oxide signaling. Frequently cited as a lead antihypertensive peptide candidate.
