Beetroot at a Glance
What It Is
Beetroot is a root vegetable naturally rich in dietary nitrates and other compounds including betalains and polyphenols. Dietary nitrates can be converted within the body into nitric oxide, a signaling molecule involved in vascular physiology and blood flow regulation.
Main Benefit
Research suggests beetroot may help support healthy blood pressure levels already within a normal range, exercise performance, and vascular function.
What to Expect
Most clinical studies evaluate beetroot as concentrated juice preparations, nitrate-standardized shots, or powders delivering approximately 300–800 mg nitrate daily.
Reported side effects may include:
• Mild gastrointestinal discomfort
• Temporary bloating
• Temporary changes in stool color
• Red or pink urine ("beeturia")
These effects are generally mild and often improve with continued use.
Medication Caution
Because beetroot influences nitrate and nitric oxide pathways, individuals using medications that affect blood pressure or vascular function should consult a healthcare professional before use.
The Verus Standard
Verus PhytoMed™ prioritizes beetroot formulations with transparent nitrate content and standardized dosing. Nitrate-standardized products are considered most aligned with the clinical research literature because dietary nitrate delivery appears to be one of the primary mechanisms evaluated in human studies.
What You’ll Learn
Beetroot has become one of the most studied functional foods for vascular and exercise physiology research. This overview summarizes:
• What beetroot is
• How it is believed to work in the body
• What current research suggests
• Typical dosing used in studies
• Safety considerations and limitations of the evidence
What Is Beetroot?
Beetroot (Beta vulgaris) is a naturally nitrate-rich root vegetable commonly consumed as:
• Whole beetroot
• Beetroot juice
• Concentrated nitrate shots
• Beetroot powder
• Capsules
Although beetroot has long been consumed as a food source, modern clinical research has increasingly focused on its nitrate content and effects on vascular physiology and exercise performance.
How Beetroot Works
Dietary nitrate from beetroot undergoes conversion within the body through several physiological steps.
Following ingestion:
Dietary nitrate → nitrite → nitric oxide
Nitric oxide functions as a signaling molecule involved in numerous physiological processes.
Research suggests beetroot may influence:
• Nitric oxide pathways
• Vascular tone and endothelial function
• Blood flow regulation
• Exercise efficiency
• Oxygen utilization during physical activity
• Mitochondrial energy pathways
• Oxidative balance pathways
These mechanisms are believed to contribute to beetroot's role in cardiovascular and exercise research.
These findings remain under investigation and should not be interpreted as proof of disease treatment.
Absorption and Metabolism
Unlike many botanical compounds, beetroot nitrate is readily absorbed.
Oral bacteria appear to play an important role in nitrate conversion. Some studies suggest antibacterial mouthwash use may reduce nitrate-to-nitric oxide conversion.
Because of this mechanism, consistent intake patterns are commonly used in research settings.
What the Research Shows
While individual studies vary, several patterns appear across randomized trials and systematic reviews.
Cardiovascular and Vascular Support
Research suggests beetroot may support: (1-4)
• Healthy blood pressure already within a normal range
• Endothelial function
• Healthy vascular responses
• Cardiovascular wellness
These findings may relate to nitric oxide-mediated effects on vascular function.
Research Summary: Across multiple meta-analyses of randomized controlled trials, nitrate-rich beetroot supplementation has been associated with reductions in systolic blood pressure of approximately 3–5 mmHg under study conditions, with smaller but favorable changes in diastolic blood pressure also reported. Effects vary based on baseline blood pressure, nitrate dose, preparation type, and study duration. (1-4)
Exercise and Performance Support
Research suggests beetroot may support: (5-9)
• Exercise efficiency
• Oxygen utilization during exercise
• Endurance performance
• Exercise tolerance
Some studies have reported reduced oxygen requirements during exercise and improvements in selected performance measures following nitrate supplementation.
Results vary based on training status, exercise type, and study design.
Other Support
Emerging research suggests beetroot may support: (10-12)
• Healthy cognitive blood flow pathways
• Normal inflammatory responses
• Oxidative balance pathways
• Healthy aging physiology
Quality and Standardization
High-quality beetroot supplements typically include:
• Transparent nitrate content
• Standardized formulations
• Third-party testing
• Manufacturing practices consistent with cGMP standards
Verus PhytoMed™ prioritizes formulations that clearly disclose nitrate content because nitrate delivery most closely reflects the preparations evaluated in human research.
Typical Research Dosing
In clinical research settings, beetroot has most commonly been evaluated at:
Dietary nitrate:
Approximately 300–800 mg daily
Common preparations include:
Concentrated beetroot juice shots
Approximately 70–140 mL
Nitrate-standardized powders
Variable powder amounts standardized to nitrate delivery
Capsules
Variable based on nitrate content
These dosing ranges reflect research protocols used in clinical studies. Individual needs may vary.
Consult a qualified healthcare professional before using any dietary supplement.
Safety and Tolerability
Beetroot has generally been well tolerated in clinical studies.
Reported side effects may include:
• Gastrointestinal discomfort
• Temporary bloating
• Stool color changes
• Red or pink urine (beeturia)
These effects are generally mild.
Individuals taking medications affecting blood pressure should consult a healthcare professional before use.
Safety Considerations
Individuals with a history of kidney stones or conditions involving oxalate metabolism should consult a healthcare professional before use.
Evidence Context
Beetroot has been evaluated in multiple randomized trials and meta-analyses.
When reviewing the research, several limitations should be considered.
Many studies:
• Last approximately 1–12 weeks
• Use different nitrate doses
• Evaluate exercise biomarkers rather than long-term outcomes
• Examine selected populations
Larger long-term studies are still needed.
Summary
Beetroot is a nitrate-rich botanical food source that has been investigated for its effects on vascular physiology, exercise performance, and nitric oxide pathways.
When standardized appropriately and used thoughtfully, it represents a scientifically grounded option within evidence-informed wellness strategies.
Supplement Options
The following products are examples that align with the formulation criteria discussed above. Not all products within a tier are identical; classification reflects general alignment with evaluation criteria.
Premium Tier
Beet It Sport Nitrate 400 Shot
Why we selected it:
Delivers nitrate content closely aligned with human clinical research
Uses standardized nitrate dosing
Frequently utilized in exercise and vascular physiology research
Premium selection based on close alignment with commonly studied preparations
Mid-Tier
Webber Naturals Beetroot Powder
Why we selected it:
• Uses Sabeet™ standardized beetroot extract with disclosed nitrate content (~100 mg per serving)
• Provides greater formulation transparency than many generic beetroot powders
• Selected based on ingredient identity, quantified nitrate content, and reasonable partial alignment with studied nitrate exposure
Availability note: This product is sold primarily through Costco and may have more limited retail availability than standard consumer formulations.
Value Tier
Lower-cost beetroot products are available; however, many do not clearly disclose dietary nitrate content or reflect formulations commonly represented in human clinical studies, making clinical alignment less certain.
