NCT06264622

Brief Summary

The goal of this clinical trial is to evaluate the dose response effect on cardiovascular disease risk factors of a Black Garlic Extract in subjects with Grade I Hypertension. The main questions it aims to answer are:

  • If the reduction in blood pressure (systolic and diastolic) is in a dose-response manner
  • If the changes in lipid profile are in a dose-response manner Participants will be randomly assign to a low dose (250 mg/day), high dose (600 mg/day) or placebo of a standardized Garlic Extract (ABG+/GarlACE) during 12 weeks
