A 2 Week, Crossover Trial of Dietary Nitrate in Chronic Obstructive Pulmonary Disease
NCT02521532 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 8
Last updated 2015-10-23
Summary
Acute consumption of dietary nitrate (as beetroot juice) has been shown to increase exercise and decrease systemic blood pressure in multiple populations, including COPD. The chronic effect of dietary nitrate in obstructive sleep apnea syndrome (OSAS) has not been reported.
