Beetroot Juice / Dietary NitrateNew
A nitrate-rich vegetable concentrate used for modest blood-pressure lowering and exercise efficiency. Dietary nitrate is converted by oral bacteria and stomach acid into nitric oxide, so dose is best thought of in milligrams of nitrate rather than millilitres of juice.
Mechanism of Action
Inorganic nitrate is reduced to nitrite by oral bacteria, then to nitric oxide in blood and tissue, promoting vasodilation and reducing the oxygen cost of submaximal exercise. Betalain pigments in beetroot add antioxidant effects. Antiseptic mouthwash and antacids blunt the conversion.
Dosing Protocol
400mg nitrate per day (about 70 mL concentrated juice or 2-3 cups of juice)
Standard starting dose based on research
Therapeutic Range
300
Minimum
800
Maximum
Daily, with or without food; for exercise, 2-3 hours before activity
Cycling Protocol
Reassess home blood pressure after 4-8 weeks. Benefit may fade if mouthwash use or antibiotics suppress oral bacteria. No formal cycling needed
Dosages are general guidelines. Individual requirements vary based on body weight, health status, and specific goals. Start with lower doses and adjust based on response.
Benefits
Primary Benefits
- A 2022 Frontiers in Nutrition meta-analysis of 7 randomized trials (218 adults with hypertension) found daily beetroot juice lowered systolic blood pressure by about 5 mmHg (95% CI -8.9 to -1.0) with moderate GRADE certainty; diastolic change was not significant
- A 2017 Advances in Nutrition review of 22 trials estimated pooled reductions of about 3.6 mmHg systolic and 1.3 mmHg diastolic, with smaller effects when nitrate-depleted juice was the placebo
- Small improvements in time-to-exhaustion and submaximal exercise efficiency in trained and untrained adults
Secondary Benefits
Safety Information
Contraindications
Do not use if any of the following apply:
- •History of calcium-oxalate kidney stones (beetroot is high in oxalate)
- •Advanced chronic kidney disease (potassium load)
- •Prescription nitrate therapy for angina without clinician guidance
- •Low baseline blood pressure or recurrent fainting

Potential Side Effects
Some users may experience:
This is not a complete list of interactions or side effects. Individual responses vary. Always start with the lowest effective dose and monitor your response. Report any adverse effects to your healthcare provider.
Quality Markers
Look for these specific quality indicators when sourcing this compound:
- Label states mg nitrate per serving (typically 300-600 mg)
- Concentrated shot or standardized powder rather than unmeasured juice
- No added sugar or unnecessary sweeteners
- Third-party tested for heavy metals (root crops can accumulate cadmium and lead)
Trusted Certifications
Note: Supplement quality varies dramatically between brands. Cheap supplements often contain fillers, incorrect doses, or contaminants. Investing in quality products from reputable manufacturers is essential for safety and efficacy.
