Beetroot juice is a rich source of dietary inorganic nitrates, which the body converts into nitric oxide (NO). NO is a critical vasodilator, meaning it relaxes and widens blood vessels. This mechanism improves blood flow, lowers blood pressure, and enhances the efficiency of oxygen use by muscles, directly supporting key pillars of cardiovascular health and physical capacity within healthspan.
Verdict
A safe, evidence-based food for cardiovascular health and exercise performance.

Protocol
- Consume 70-140 mL of concentrated beetroot juice (providing 300-600 mg of nitrate) 2-3 hours before exercise for performance benefits.
- For chronic blood pressure management, daily consumption of 250 mL of standard beetroot juice is a commonly studied protocol.
Flags
- Can cause beeturia (harmless red or pink urine and stools).
- High in oxalates, which may contribute to kidney stone formation in susceptible individuals.
- May interact with nitrate-based medications (e.g., nitroglycerin) or PDE5 inhibitors.
- Hypotensive effects can be additive with blood pressure-lowering medications.
