The Effects
Your vascular system powers everything you do—from how clearly you think to how easily you move, rest, and recover. When circulation is strong and your heart is supported, daily life simply feels better: less fatigue, steadier energy, sharper focus, faster recovery, and more restorative rest. Used together, Arterosil HP® and Vascanox HP® help you build and sustain the foundation for lifelong vitality—so you can do more of what you love.*
This Bundle Supports:
A healthy heart and cardiovascular health*
Vascular integrity and healthy circulation to help blood move where it’s needed*
Maintenance of healthy arteries for long-term cardiovascular resilience*
A strong endothelial glycocalyx—the body’s vascular foundation for endurance and healthy aging*
We want to optimize our vascular biology. We need to do that through supporting the glycocalyx and returning nitric oxide to our former glory, like we all had in our 20s and 30s.”

The Science
Comprehensive vascular support from the inside out.*
Calroy’s science-driven approach to vascular health targets both structure and signaling. Arterosil HP® focuses on restoring the endothelial glycocalyx that regulates permeability and protects against stress.* Vascanox HP® focuses on supporting nitric oxide availability that helps blood vessels relax, improving oxygen delivery to muscles and organs.* Together, these complementary pathways enhance overall vascular health, promoting endurance, clarity, and long-term cardiovascular wellness.*
It performs critical functions, including:
- Protects blood vessels
- Shields sensitive barriers like the blood-brain barrier
- Stores protective compounds that support repair and resilience
- Regulates what passes into vessel walls
- Triggers nitric oxide for blood flow and flexibility
When the glycocalyx is compromised, circulation is affected and every organ feels the impact. Protecting this structure is essential to maintaining resilient blood flow, cardiovascular health, and systemic vitality.
Scientists only recently discovered the endothelial glycocalyx, but it is now recognized as one of the most important structures in human health. This microscopic gel lining performs countless jobs that keep your blood vessels healthy, flexible, and resilient. Because of its critical role in healthy heart and vascular function, protecting the endothelial glycocalyx has become a key focus of modern vascular research.
We routinely utilize Vascanox HP to improve nitric oxide function as well as support the endothelial glycocalyx with Arterosil HP. We discuss with patients how these supplements help act as a "force field" for the arteries.

Ingredients & How to Use
Arterosil HP is uniquely powered by MonitumRS, a patented extract of rhamnan sulfate from a rare green seaweed sustainably harvested in the Pacific Ocean. Rhamnan sulfate is a powerful glycocalyx-regenerating compound (GRC). MonitumRS helps restore and protect the endothelial glycocalyx—supporting circulation, vascular integrity, and the health of every organ and system.*
Take 2 capsules daily, with or without food.
Vascanox HP features Noxa24, Calroy’s patented extract blend of fermented black garlic, beetroot, and bilberry, combined with potassium nitrate and fruits and vegetables featuring polyphenols. Together, these bioactives nourish the body’s nitric oxide pathways—supporting healthy circulation, vascular flexibility, and endurance throughout the day.*

Frequently Asked Questions
Why use these two supplements together?
Why use these two supplements together?
Because vascular health depends on both structure and function. Arterosil HP® protects the glycocalyx (the vessel lining), while Vascanox HP® sustains nitric oxide (the molecule that keeps blood flowing smoothly). Together, they deliver comprehensive vascular support.*
Can I take them at the same time?
Can I take them at the same time?
Yes. You can take them together or at separate times of the day, whichever fits best into your routine.*
