Beetroot (Nitrate Donor)
“The Nitric Oxide Switch.” A targeted way to restore nitric-oxide signalling for blood flow, pressure control, and oxygen efficiency.
The Naturopathic Perspective
“The Nitric Oxide Switch.”
From a naturopathic lens, beetroot (as a nitrate donor) is less a “superfood” and more a physiologic lever for vascular tone and oxygen efficiency. Many modern patients live in a state of functional nitric oxide (NO) deficit—driven by endothelial stress, oxidative load, and metabolic strain. Beetroot nitrates feed the nitrate → nitrite → NO pathway, a NOS-independent route that bolsters NO signaling when the classic L-arginine route is underperforming.
Clinically, that translates into a tool we reach for when we want to improve perfusion and “flow”—not as hype, but as a measurable shift in hemodynamics and exercise economy. The key is that dietary nitrate is actively recycled via the enterosalivary pathway: nitrate is concentrated into saliva, reduced by oral bacteria to nitrite, and then converted to NO exactly where tissues need it most.
💡 Clinical Insight: The Depletion Gap
Why not just food?
1. Microbiome Suppression: Antibacterial mouthwash (and some antibiotics) can reduce nitrate-reducing oral bacteria, blunting conversion to nitrite—so intake may be there, but biochemical activation is blocked.
2. Variable Content: Season, sunlight, and farming methods shift nitrate levels substantially, so “a serve of greens” doesn’t reliably equal a therapeutic dose.
“We prescribe this to bridge the gap between biological necessity and modern depletion.”
Naturopathic Use Cases
How we use this in clinical practice, validated by evidence.
1. High Blood Pressure Support
Clinical Goal: Vasodilation
The Clinical Logic:
We use nitrate-rich beetroot to increase NO bioavailability, leading to vascular smooth muscle relaxation (vasodilation) and improved endothelial function. The nitrate–nitrite–NO pathway provides support even when eNOS function is impaired.
Clinically, this helps the “tight-vessels” phenotype—mild hypertension, cold extremities, and headaches linked to vascular tone.
Very High
Grade A
Verdict: Meta-analyses in hypertensive populations generally show clinically relevant reductions in BP, with the most consistent signal for systolic BP. Effects depend on the integrity of oral bacteria.
2. Exercise Performance & Economy
Clinical Goal: Oxygen Efficiency
The Clinical Logic:
Beetroot nitrates raise NO signaling, improving blood flow distribution and mitochondrial contractile economy. This means the body may do the same work with slightly less oxygen demand—a “margin tool” for athletes and deconditioned patients.
Moderate
Grade B
Verdict: Data support a real but small performance benefit, most consistent in recreationally active individuals. Highly trained athletes may see less benefit. Dosing timing is critical.
3. Biological Function: NO Signaling
Clinical Goal: Tissue Perfusion
The Clinical Logic:
This is foundational biochemistry: dietary nitrate is absorbed, concentrated in saliva, reduced by oral bacteria to nitrite, and further reduced to NO. This supports vasoregulation and perfusion, especially in hypoxic or acidic conditions where NO is most needed.
Incontestable
Grade A
Verdict: Established biological fact. Core human physiology.
Form Matters: Quality Comparison
Why we prescribe Standardised Shots over other forms.
The “Hero” Form
We prioritize Standardised Nitrate Beetroot Juice Concentrate (“Shots”). This provides dose certainty (mmol/mg) + predictable timing. Clinical trials rely on this model because vegetable nitrate content varies too wildly to be a reliable therapeutic intervention.
Food Sources (Approximate)
Nitrate content varies by season and farming method.
Spinach (Raw)
~65 mg
(Per Cup)
Beetroot (Cooked)
~150 mg
(Per 100g)
Celery
~90 mg
(Per 2 Stalks)
Lettuce
~40 mg
(Per 50g Serve)
