IRW peptide

Cardiovascular Research only Animal studies

Also called Ile-Arg-Trp

A three-amino-acid peptide first identified in egg white protein (ovotransferrin). It inhibits ACE and raises ACE2, two enzymes with opposing roles in blood pressure control. In hypertensive rats it lowered blood pressure and reduced vascular inflammation.

Why people take it

• Reduced vascular inflammation markers in rodents

Worth knowing: Animal only, and derived from a food protein studied mostly as a dietary ingredient.

Status: Animal and cell research only.
