The goal of this clinical trial is to verify the hemodynamic and biomarker responses of beetroot juice intake in postmenopausal women with hypertension. The main questions it aims to answer are: Is beetroot juice dose related to better hemodynamic responses in hypertensive postmenopausal women? Is beetroot juice dose related to better oxidative stress profile responses in hypertensive postmenopausal women? The investigators will conduct a parallel clinical study with 10 days of intervention, in which 48 women will be randomized into 3 groups: 1) Two shots of beetroot juice intake per day (800mg of NO3-); 2) One shot of beetroot juice intake per day (400mg of NO3-); 3) placebo intake (beetroot juice without NO3-).
