Beet juice shows promise for heart and lung health in small study
NCT ID NCT04920799
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested whether drinking beet juice twice daily for two weeks could improve blood vessel function and breathing muscle strength in older adults with coronary artery disease. Eight participants were randomly assigned to receive either nitrate-rich beet juice or a placebo version, then switched after a break. The main goal was to see if a larger trial is feasible, not to prove effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
beetroot juice (nitrate-rich)
What this could lead to
If it works, this could point toward a simple dietary supplement to support heart and breathing health in older adults with coronary artery disease.
What could go wrong
This is a very small pilot study with only 8 participants, designed mainly to test feasibility. Results may not apply to everyone, and any benefits need confirmation in larger trials.
