Beetroot / Dietary Nitrate
Also known as: Beet juice, Nitrate
Beetroot provides dietary nitrate, commonly explored for exercise performance and circulation. Evidence is moderate for endurance contexts. Effects vary, and it can temporarily tint urine or stools red (harmless).
Snapshot
Evidence level is outcome-specific; a supplement can have stronger evidence for one use and limited evidence for another.
What this page can tell you: Commonly discussed timing, food notes, caution categories, and an honest note on how much source review this entry still needs.
What it cannot: Whether this is appropriate for you personally, or that it treats, prevents, or cures any condition. Informational only — discuss with a clinician or pharmacist.
🕒 Timing
When: Afternoon, With a meal
Food: With or without food
For performance it is commonly taken about 2-3 hours before activity. Antibacterial mouthwash (and even strong mints) can blunt the effect, since mouth bacteria are part of how nitrate is converted.
💊 Common use range
300–600 mg nitrate
Follow product guidance.
Ranges are informational, not a recommended dose. Talk to a professional about what is right for you.
⚠️ Commonly noted interactions (supplements)
None listed.
Often about absorption or timing rather than danger — separating doses is common. This list is not exhaustive.
🧭 Baseline caution
General caution for ordinary, common use — before accounting for your specific dose, medications, health history, or procedures.
No general caution factors flagged for ordinary use. See context alerts below for situations that may still apply to you.
Caution level is an informational summary of commonly discussed caution categories and doses — not a safety rating, approval, or medical advice. Low caution does not mean safe for you.
🔎 Context alerts to review
Context alerts may matter depending on your dose, medications, health history, or procedure plans — they do not mean the supplement is generally risky at ordinary use.
Medications
- Higher caution if you take blood-pressure medication
🩺 Medication caution categories
- Blood pressure medication — Some items can nudge blood pressure on their own, so combined with blood-pressure medication the effects could add up. Discuss monitoring with your clinician.
🏥 Surgery & procedure caution
May lower blood pressure; share use with your care team before procedures.
If you have a procedure scheduled, bring your full supplement list to your surgical and anesthesia team. Do not stop prescribed medication unless your clinician tells you to. Do not start or stop supplements based only on this app.
✅ Quality checklist
- Prefer products with third-party testing or a certificate of analysis (COA).
- Check the label for the exact form and the elemental or active amount per serving.

🔬 Evidence snapshot
NIH ODS: nitrate from beetroot juice may modestly improve aerobic-endurance performance, but results are inconsistent and benefits are more likely in recreationally active people than in elite athletes. Typical research dosing is about 500 mL/day of beetroot juice (~5-11 mmol / 310-682 mg nitrate), converted to nitric oxide, a vasodilator. Beeturia (harmless red urine) can occur.
