A 12-week study found that daily beetroot juice supplementation significantly lowered blood pressure and improved exercise capacity in people with chronic obstructive pulmonary disease (COPD). This suggests that beetroot, rich in dietary nitrates, could be a safe and well-tolerated alternative or complement to conventional antihypertensive medications for COPD patients. While further research is needed to confirm long-term benefits and potential interactions with other medications, the study offers encouraging evidence for the potential of beetroot juice as a natural approach to managing COPD symptoms.
