Kudzu Root for Blood Pressure Regulation

Research suggests that kudzu root extract may support blood pressure regulation, with one animal study finding reductions of 11–15 mmHg in a rat strain genetically predisposed to hypertension and stroke after two months of dietary supplementation. That same study also observed improvements in blood glucose, insulin levels, and cholesterol, and notably these effects appeared regardless of estrogen status, suggesting the active isoflavone compounds may act through pathways independent of sex hormones. However, the current evidence base is limited to a single preclinical animal study, and it remains unclear whether these findings would translate to humans, as animal models of hypertension do not always reflect the complexity of human cardiovascular physiology. Human clinical trials, including randomized controlled trials, would be needed before drawing any firm conclusions about kudzu root's role in blood pressure management in people.
