What If High Blood Pressure Is a Two-Part Problem—and Most Solutions Only Address One Pathway?
What If High Blood Pressure Is a Two-Part Problem—and
Most Solutions Only Address
One Pathway?
Conventional solutions focus on vascular tension—but oxidative stress remains. When half the problem is left unaddressed, many people are left managing side effects and chasing a solution that never fully works.

Practicing Naturopathic Physician
In more than two decades of caring for patients at my clinics in the Washington, DC area, high blood pressure has remained one of the most common concerns I see. The story is almost always the same.
People follow the conventional path. Their numbers improve. But they don't always feel better—they feel fatigued, lightheaded, swollen in their legs and ankles. Some notice a significant drop in libido or sexual function that no one warned them about. Less like themselves in ways that matter. Eventually, many stop taking action altogether. And their blood pressure climbs back up.
Most conventional approaches treat high blood pressure primarily as a problem of vascular tension: arteries constrict, pressure rises, and the goal becomes forcing those arteries to relax. That addresses an important pathway. But it doesn't address what's happening inside the arterial wall itself.
Oxidative stress damages the delicate endothelial lining that helps blood vessels stay flexible and responsive. Over time, this reduces nitric oxide production, impairs healthy dilation, and creates conditions that make healthy blood pressure harder to maintain—regardless of what else you're doing.
"Lowering a number isn't the same as solving the whole problem. Blood pressure readings tell you what's happening on the surface, but they don't reveal everything that's happening inside the arterial wall. That's why I spent years looking for a protocol that addresses more than the number alone."
What I eventually found—and what the clinical research supports—is that healthy blood pressure depends on addressing both vascular tension and oxidative stress simultaneously. Not by overriding your biology, but by supporting the systems that help arteries stay flexible, responsive, and healthy over time.
The two-part problem
Blood Pressure Is Controlled By Two Mechanisms.
Most Solutions Only Target One.
Blood Pressure Is Controlled
By Two Mechanisms.
Most Solutions Only Target One.
Most approaches focus on vascular tension and that matters. But oxidative stress inside the arterial wall is equally important, and almost universally overlooked. The two cards below show why addressing both is the only way to support the complete picture.
Not standardized or citrinin-free
Part 1: Vascular tension
Signals such as angiotensin tell blood vessels when to constrict. As arteries tighten, resistance increases and blood pressure rises.
Widely addressed
Not standardized or citrinin-free
Part 2: Oxidative stress
Free radicals can impair the endothelial lining and reduce nitric oxide production, making blood vessels less flexible and responsive.
Almost universally ignored
These pathways don't operate independently. Reducing the signals that tell blood vessels to constrict is important. But blood vessels must also remain capable of responding when those signals are reduced. When oxidative stress impairs nitric oxide production and endothelial function, arteries become less flexible and less responsive. That's why supporting healthy blood pressure isn't just about reducing constriction. It's also about preserving your blood vessels' natural ability to relax.
The dual-action protocol
Two Plant Extracts.
Two Pathways.
Two Plant Extracts. Two Pathways.
After years of reviewing the literature, I kept returning to the same two ingredients—not because they were trendy, but because they are among the few with peer-reviewed human clinical research supporting their effects on both pathways involved in healthy blood pressure regulation.

After 20 Years of Searching, I Finally Built
What My Patients Couldn't Find
After 20 Years of Searching,
I Finally Built What My Patients Couldn't Find
Over the years, I reviewed hundreds of studies, evaluated countless ingredients, and watched patients spend money on products that looked impressive on the label but failed to deliver meaningful results.
The challenge wasn't finding promising ingredients.
The challenge was finding ingredients supported by strong clinical research, using them at the doses that were actually studied, and combining them in a way that addressed both pathways involved in healthy blood pressure regulation.
Eventually, I stopped looking for that formula. I built it.
"I wanted to create something I could hand to a patient who wanted a natural approach to lowering their blood pressure and say: this is the exact protocol the human clinical data supports. These are the ingredients. These are the doses. Take this formula exactly as formulated."
The result is Durable BLOOD PRESSURE®—the only formula in the world that combines the full clinical doses of both Enovita® Grape Seed Extract (300mg) and Benolea® Olive Leaf Extract (1,000mg) in a single, two-capsule daily protocol.
It's not a collection of trendy ingredients. It's not a proprietary blend hiding underdosed extracts behind an impressive label. It's the exact dual-action protocol I developed over two decades of clinical practice—formulated around what peer-reviewed human studies actually show works, at the doses that actually produced those results.
Two capsules a day. Two clinically proven extracts. One protocol built to do what most natural supplements simply don't: move your numbers—fast—and keep them there.

DR. PASSERO'S FORMULATION STANDARDS
What I Look For Before An Ingredient Earns a Place in a Formula
The quality of a supplement is determined long before it reaches the bottle. After more than two decades in practice, these are the standards I use when evaluating every ingredient that goes into a formula.

After more than two decades in practice, these are the standards I use when evaluating every ingredient that goes into a formula.
These standards are what led me to Enovita® grape seed extract and Benolea® olive leaf extract. Not because they were popular. Not because they were easy to source. Because they consistently stood out when measured against the standards that matter most.
