Beetroot Powder
Clinical dose: 300-600mg of dietary nitrate daily (equivalent to approximately 70mL concentrated beetroot juice or 15-30g of unstandardized powder)
At a Glance
Beetroot supplementation works primarily through its dietary nitrate content, which is converted to nitric oxide (NO) via the nitrate-nitrite-NO pathway. This pathway depends on oral bacteria to reduce nitrate to nitrite, which is why antibacterial mouthwash can blunt the effects. Our top pick is Beet It Sport Nitrate 400 Shot (Grade: B+, $3.33/day).

What Is Beetroot Powder?
Beetroot supplementation works primarily through its dietary nitrate content, which is converted to nitric oxide (NO) via the nitrate-nitrite-NO pathway. This pathway depends on oral bacteria to reduce nitrate to nitrite, which is why antibacterial mouthwash can blunt the effects. The evidence base is strongest for concentrated beetroot juice products that deliver a standardized nitrate dose. For exercise performance, a systematic review and meta-analysis (PMID: 24791915) found that dietary nitrate supplementation significantly improved exercise tolerance and time to exhaustion, particularly in recreational athletes. The effect is most pronounced when taken 2-3 hours before activity, aligning with peak plasma nitrite levels. Bailey et al. (PMID: 21284382) demonstrated that beetroot juice reduced the oxygen cost of walking and moderate-intensity running, an effect not typically seen with other ergogenic aids. For blood pressure, a randomized controlled trial by Kapil et al. (PMID: 25578818, n=68) showed that daily dietary nitrate from beetroot juice significantly lowered both systolic and diastolic blood pressure in hypertensive patients over 4 weeks. The effect was clinically meaningful and comparable to some first-line antihypertensive medications. A key consideration is that unstandardized beetroot powders and capsules do not disclose their nitrate content, making it impossible to verify whether a given product delivers the 300-600mg nitrate dose used in clinical trials. Concentrated juice shots like Beet It Sport are the only format that consistently matches the research protocol. Jones et al. (PMID: 23640589) confirmed that the oxygen-sparing effect requires adequate nitrate doses, reinforcing that product format and standardization matter enormously.
Does It Work? The Evidence
| Claimed Benefit | Evidence Level | Key Studies | Our Verdict |
|---|---|---|---|
| Improved exercise tolerance and endurance | Strong | Systematic review (PMID: 24791915): significant improvement in time to exhaustion; Bailey et al. (PMID: 21284382): reduced oxygen cost of walking and running | Works |
| Blood pressure reduction | Strong | Kapil et al. 2015 RCT (n=68, PMID: 25578818): significant systolic and diastolic BP reduction in hypertensive patients over 4 weeks | Works |
| Reduced oxygen cost of submaximal exercise | Strong | Jones et al. 2013 (PMID: 23640589): dietary nitrate reduces VO2 during steady-state exercise, allowing more work at lower metabolic cost | Works |
How to Choose: Forms, Doses & What Matters
Clinical dose: 300-600mg of dietary nitrate daily (equivalent to approximately 70mL concentrated beetroot juice or 15-30g of unstandardized powder)
Best forms: Concentrated beetroot juice (shots), Standardized beetroot extract (nitrate content verified), Nitrate salts (e.g., arginine nitrate)
Consume 2-3 hours before exercise for performance benefits, as this aligns with peak plasma nitrite levels. Do not use antibacterial mouthwash or chew gum immediately before or after ingestion, because oral bacteria are required to convert nitrate to nitrite. A loading protocol of 3-7 days of daily intake leading up to an event may enhance benefits compared to a single acute dose. For blood pressure support, take daily at a consistent time.

Who Should Take Beetroot Powder?
Endurance athletes such as runners, cyclists, and swimmers seeking a legal ergogenic aid. Adults looking for non-pharmacological blood pressure support. Older adults aiming to improve exercise capacity and circulation. The evidence is strongest for recreational and moderately trained athletes; elite athletes may see smaller benefits.
Who Should Avoid It?
Individuals taking PDE5 inhibitors (e.g., sildenafil) or strong prescription antihypertensives, as combining these with dietary nitrate may cause severe hypotension. People with a history of calcium oxalate kidney stones should avoid beetroot due to its high oxalate content. Those with severe kidney dysfunction should also steer clear.
Side Effects & Safety
Beeturia (harmless red or pink discoloration of urine and stool) is extremely common and not a cause for concern. Mild gastrointestinal discomfort can occur at higher doses. Transient drops in blood pressure are possible, particularly in those already taking antihypertensive medications. Doses exceeding approximately 900mg of nitrate do not appear to offer additional performance benefits and may increase GI distress.
Frequently Asked Questions
Why are beetroot capsules scored so poorly compared to juice shots?
The clinical evidence for beetroot is based on its dietary nitrate content, typically 300-600mg. A standard 1000mg beetroot capsule contains roughly 5-15mg of nitrate - meaning you would need 20-40 capsules to reach a clinical dose. Concentrated juice shots deliver the full research dose in a single serving. Capsules are not a practical delivery method for this supplement.
Does beetroot powder work as well as concentrated juice?
Unstandardized beetroot powder does not disclose its nitrate content, so there is no way to verify you are getting a clinical dose. You would typically need 15-30g of powder to approximate the nitrate content of a single 70mL concentrated juice shot. If the powder is from a juice concentrate, it may be somewhat more potent per gram, but without standardization this remains guesswork.
Can mouthwash reduce the effectiveness of beetroot supplements?
Yes. Antibacterial mouthwash kills the oral bacteria (particularly on the tongue) that are essential for converting dietary nitrate to nitrite, the first step in nitric oxide production. Studies show that mouthwash use can significantly blunt the blood pressure and performance benefits of dietary nitrate. Avoid mouthwash for at least 2 hours before and after taking beetroot.
How long before exercise should I take beetroot juice?
Most clinical trials administer beetroot juice 2-3 hours before exercise, which aligns with peak plasma nitrite levels. Some evidence suggests a multi-day loading protocol (3-7 days of daily dosing) provides greater and more consistent benefits than a single acute dose.
Is beetroot supplementation effective for elite athletes?
The benefits appear to be smaller in highly trained/elite athletes compared to recreational or moderately trained individuals. This may be because elite athletes already have optimized nitric oxide pathways. However, even small improvements can be meaningful at the elite level, and some studies show benefits for repeated sprint performance in trained athletes.
Can I use beetroot for blood pressure instead of medication?
Beetroot juice has shown clinically meaningful blood pressure reductions in some trials, but it should not replace prescribed antihypertensive medication without your doctor's approval. It may be a useful complementary approach. Do not combine with PDE5 inhibitors or strong blood pressure drugs without medical supervision due to the risk of hypotension.
