A Word From Dr. Bradley

Why I recommend
Blood Flow Support™

In my decades of clinical practice — from military medicine across three conflict zones to corporate health strategy at some of America's largest organizations — one truth keeps surfacing: circulation is foundational. It is not a niche concern. It is not a gym-adjacent performance hack. It is the quiet system beneath every other system.

Nitric oxide is the molecule that governs that system. Its discovery earned a Nobel Prize in Physiology or Medicine in 1998, and what we have learned since confirms what the body has always known: when nitric oxide availability declines — and it does decline with age, stress, and sedentary living — the downstream effects show up everywhere. Energy, cognition, circulation to the extremities, cardiovascular resilience, even sexual wellness.

Blood Flow Support™, powered by Calroy's proprietary Noxa24™ formulation, is the most clinically thoughtful daily nitric oxide support product I have encountered. It does not chase a momentary spike. It targets the full biotransformation cycle — production, storage, and release — and a published human clinical trial documented salivary nitric oxide levels sustained above baseline for a full 24 hours. That is a meaningful distinction.

I recommend it because it is honest, it is science-grounded, and it matches how the body actually works. Use the link on this page to order and receive 10% off every bottle — my way of making this accessible to anyone who wants to take circulation seriously.

The Problem

Nitric oxide declines
before symptoms appear.

Most people don't notice their circulation declining. The body compensates, quietly, until it can't. By the time reduced energy, cold extremities, or blood pressure changes appear, the underlying NO deficit has often been building for years.

⚡

What NO decline looks like in daily life

Reduced exercise capacity and slower recovery. Lower sustained energy across the day. Challenges maintaining healthy blood pressure as vessels lose flexibility. Diminished circulation efficiency to extremities and organs. Sexual wellness changes linked to vascular function. These are not isolated symptoms — they share a common upstream signal.

The Mechanism

Three pathways.
One daily dose.

Most nitric oxide supplements target only one step in a multi-step process. Blood Flow Support™, powered by Noxa24™, supports the entire biotransformation cycle — from production through storage to sustained release.

🏭
Step 01 · Production

Two routes to synthesis

Nitric oxide is produced via the NOS (nitric oxide synthase) pathway in vascular endothelial cells and the nitrate-nitrite-NO pathway via dietary nitrate. Blood Flow Support™ targets both simultaneously — a multi-pathway approach that most competitors ignore.

🫙
Step 02 · Storage

Nitrite as a reservoir

Potassium nitrate — the primary NO precursor in the Noxa24™ blend — is converted to nitrite in the salivary glands and concentrated there. This creates a biological reservoir that the body draws on throughout the day, rather than a single rapid burst.

🌊
Step 03 · Release

24-hour sustained flow

S-allylcysteine (SAC) from garlic — a hydrogen sulfide precursor — enhances NO release and bioavailability. The polyphenol antioxidant complex protects NO from oxidative degradation. Together, this produces the sustained 24-hour NO signal documented in the published clinical trial.

The Research

Built on science that
earned a Nobel Prize.

The physiological role of nitric oxide was established in the 1990s and recognized with the Nobel Prize in Physiology or Medicine in 1998. Blood Flow Support™ is built on that foundation — and extended by published human study data specific to this formulation.

Published Human Trial · Cureus, 2023

24-hour nitric oxide elevation demonstrated in human subjects

An open-label clinical trial of Vascanox HP (the clinical name of the Noxa24™-powered formulation) in hypertensive subjects measured salivary nitrite — a validated surrogate biomarker of NO bioavailability — at 2, 6, and 24 hours after a single dose. NO levels peaked at 743 μM at 2 hours and remained significantly elevated at 348 μM at the 24-hour mark, well above baseline.

Published Human Trial · Blood Pressure Outcomes

11 mmHg systolic reduction in hypertensive adults at 2 weeks

The same four-week trial enrolled 12 participants with elevated blood pressure or mild hypertension. Daily supplementation produced a statistically significant 11 mmHg reduction in systolic blood pressure at two weeks (p<0.001) that persisted through the four-week assessment. Diastolic pressure was also significantly reduced in hypertensive participants. The supplement was described as "safe, effective, quick-acting, and long-lasting."

🏆

The 1998 Nobel Prize in Physiology or Medicine

Awarded to Robert F. Furchgott, Louis J. Ignarro, and Ferid Murad for their discovery of nitric oxide as a signaling molecule in the cardiovascular system. Their work established that the vascular endothelium produces NO to regulate blood pressure, blood flow, and vascular tone — the same biology that Blood Flow Support™ is designed to reinforce. This is not marketing language. It is foundational physiology with the highest scientific recognition in medicine.

What makes Noxa24™ different

The supplement market is saturated with products that flood the body with arginine or citrulline — precursors to the NOS pathway only — and produce a short, sharp NO spike that fades within hours. Noxa24™ was designed around a different question: how does the body actually produce, store, and release nitric oxide across the full day?

🌿
Potassium Nitrate
Dietary inorganic nitrate — the primary precursor for the nitrate-nitrite-NO pathway. Concentrated by the salivary glands and converted to nitrite by oral bacteria, then reduced to NO in the stomach and vasculature. This pathway is active even under low-oxygen and low-pH conditions where the NOS pathway underperforms.
🧄
S-Allylcysteine (SAC) — Garlic Extract
A hydrogen sulfide (H₂S) precursor from aged garlic extract. H₂S acts synergistically with NO to protect vascular function and enhance NO bioavailability — a recently discovered interaction between two gasotransmitter systems. SAC is the specific compound studied in the published Cureus trial.
🫐
Antioxidant-Rich Polyphenol Complex
A proprietary blend of polyphenols derived from fruits and vegetables. Nitric oxide is highly reactive and can be rapidly inactivated by free radicals. The polyphenol complex scavenges oxidative species that would otherwise degrade NO before it can act on vascular smooth muscle — extending the effective window of NO action.

How is this different from other nitric oxide supplements?
Most NO supplements rely exclusively on arginine or citrulline — amino acid precursors to the NOS pathway only. These produce a sharp NO spike of 2–4 hours and are largely marketed as pre-workout products. Blood Flow Support™ targets both the NOS pathway and the nitrate-nitrite-NO pathway simultaneously, using potassium nitrate and the H₂S-generating compound S-allylcysteine from garlic, plus an antioxidant polyphenol complex that protects NO from oxidative degradation. A published human trial demonstrated NO levels above baseline for 24 hours from a single daily dose — a differentiation that is not a marketing claim but a measured outcome.
What does the clinical trial actually show?
A 4-week, open-label clinical trial published in Cureus (2023) enrolled 12 participants with elevated blood pressure or mild hypertension. Key results: salivary nitrite (a validated NO biomarker) peaked at 743 μM at 2 hours post-dose and remained elevated at 348 μM at 24 hours, confirming sustained NO availability from a single daily dose. Systolic blood pressure decreased by approximately 11 mmHg at 2 weeks (p<0.001) and was maintained at 4 weeks. Diastolic pressure also decreased in hypertensive participants. The supplement was characterized as "safe, effective, quick-acting, and long-lasting." As an open-label trial with 12 participants, it is exploratory evidence — not a definitive Phase 3 RCT. But it is real human data, published and peer-reviewed, and the results are clinically meaningful.
Does it contain stimulants? Can I take it with other supplements?
Blood Flow Support™ contains no stimulants, caffeine, or adrenergic compounds. It is formulated for daily, consistent use. It pairs naturally with Vascular Shield™ (arterial structure support) and MoveEase™ (movement and joint support) as part of a comprehensive vascular wellness protocol. It is gluten-free, dairy-free, soy-free, vegan, and non-GMO. As with all supplements, individuals on antihypertensive medications should consult their physician before starting, as the blood pressure effects observed in the trial may be additive.
Why does Dr. Bradley recommend this product specifically?
Dr. Bradley's clinical background spans military medicine, corporate population health, and precision wellness. His standard for recommending any supplement is: a clear, biologically plausible mechanism; human study data supporting that mechanism; and manufacturing quality transparency. Blood Flow Support™ meets all three. The Nobel Prize–grounded nitric oxide biology is unambiguous. The Noxa24™ formulation is patent-protected and cGMP-manufactured. And the Cureus published trial provides real human outcome data specific to this formulation. This is not a sponsorship endorsement — it is a physician's assessment of the available evidence.
