Prehypertension Study

Measuring the impact of rice vinegar on blood pressure in prehypertensive adults

Medical device used to measure blood pressure.


A multinational food company needed to assess the safety and efficacy of rice vinegar as a treatment for pre-hypertensive adults, and those at high risk of Cardiovascular disease.


This hybrid study collected clinical safety and efficacy data from a diverse population of patients with blood pressure of 120-139/80-89 mmHg. Emphasis was placed on ensuring representation of African American participants as this population over-indexes for high blood pressure.  Between site visits, subjects completed daily questionnaires and chatted with the study team via the app, receiving daily reminders to report product compliance and health-related changes.


Successful recruitment of a diverse population: 41% Caucasian, 39% African American, 20% "other race."
Minimization of site visits via remote monitoring, facilitated the collection of 56,286 data points which were reviewed in real time.
The virtual team’s regular engagement with participants helped to achieve an 89% retention rate.
