The Claim

Daily consumption of beetroot juice containing 6.1 mmol of inorganic nitrate for one week improves submaximal aerobic endurance by 24% in older adults with heart failure with preserved ejection fraction (HFpEF), as measured by increased time to exhaustion during cycling at 75% of maximal power output.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Drinking beetroot juice every day for a week can help older adults with a certain type of heart condition ride a stationary bike longer before getting tired, which might make everyday activities easier for them.

See the scientific wording

One week of daily consumption of beetroot juice containing 6.1 mmol of inorganic nitrate improves submaximal aerobic endurance by 24% in older adults with heart failure with preserved ejection fraction (HFpEF), as measured by increased time to exhaustion during cycling at 75% of maximal power output, suggesting a potential non-pharmacological strategy to enhance daily functional capacity in this population.

  1. Study: One Week of Daily Dosing With Beetroot Juice Improves Submaximal Endurance and Blood Pressure in Older Patients With Heart Failure and Preserved Ejection Fraction.

    The study gave older heart patients beetroot juice every day for a week, and they could cycle longer without getting as tired—exactly what the claim said would happen.
