What is Beetroot / Nitrates?
Dietary nitrates that convert to nitric oxide for improved blood flow and endurance.
Beetroot is rich in dietary nitrates that convert to nitric oxide, improving oxygen efficiency and exercise capacity. Benefits are most pronounced for endurance activities and at altitude. Effects require consistent intake.
What the evidence says
The overall evidence grade for Beetroot / Nitrates is B (moderate — mixed or smaller trials, reasonable mechanistic support). Good evidence for endurance benefits, particularly in recreational athletes.
Specific findings with supporting evidence:
- Improves exercise efficiency. Evidence grade B.
- May enhance endurance performance. Evidence grade B.
- Supports blood pressure regulation. Evidence grade B.
Best-supported outcomes:
- Improved exercise economy.
- Enhanced endurance.
- Blood pressure support.
Where marketing outpaces evidence:
- Marketing often overstates: Massive performance gains.
- Marketing often overstates: Works equally for elites.
Dose and timing
The typical effective dose for Beetroot / Nitrates is 300–600 mg nitrate. ~500ml beet juice or equivalent; 2-3 hours pre-exercise.
Take it in the morning and afternoon. 2-3 hours before exercise for acute use.
Who it's for, and who should skip it
Most relevant for:
- Endurance athletes.
- Those seeking natural performance support.
- Blood pressure support.
Not appropriate for:
- Those on blood pressure medication without guidance.
- Elite athletes (smaller effects).
Safety and cautions
Caution: Blood pressure. Can lower blood pressure; monitor if on BP meds. GI effects. May cause stomach upset in some people. Red urine/stool. Harmless discoloration from beet pigments.
Common mistakes
- Expecting immediate effects.
- Using mouthwash (kills nitrate-converting bacteria).
- Underdosing.
Myths vs reality
A common misconception: Beetroot works instantly. In reality, consistent intake for several days optimizes effects.
How it interacts with other compounds
- Beetroot / Nitrates works well alongside l citrulline — different pathways to nitric oxide.
Questions people ask
Juice vs powder vs whole beets? Concentrated juice or powder is more practical for consistent dosing.
