Postmenopausal women and their endothelium: Is dietary nitrate supplementation protective?

Heart disease is the leading cause of death in the United States. The loss of estrogen from menopause puts women at a greater risk of developing heart disease. The purpose of this study is to determine the effects of drinking beetroot juice on measures of blood vessel health and blood pressure. Participants will drink beetroot juice and placebo juice each for one week followed by blood pressure measurements and ultrasound imaging of an artery in the upper arm. A sub-aim of this study is to investigate the effects of estrogen status on blood vessel function between pre- and post-menopausal women.

There are a total of 6 in-person visits to the Clinical Research Center. You will be asked to drink beetroot juice (2 oz) every day for 7 days. Participants will undergo vascular assessments, blood pressure measurements, and blood draws (11 in total for 6 visits).
