By supporting normal circulation, normal artery function, a healthy heart, and helping maintain a healthy artery wall, Arterosil HP Professional plays a foundational role in overall health.*
Why Endothelial Glycocalyx Support?
Discovered only in recent decades, the endothelial glycocalyx (EGX) is the key to vascular health. It is an upstream target for supporting vascular health. Since the vascular system supports every single organ and system in the body, it has transformative potential for lifelong health and wellness.
Thoughtfully Sourced, Quality Controlled, Vegan
Arterosil HPe uniquely contains MonitumRST, a proprietary extract of rhamnan sulfate, a specialized sulfated polysaccharide derived from the rare green seaweed, Monostroma nitidum. Rhamnan sulfate is a powerful glycocalyx-regenerating compound MonitumRStM is enhanced with an added combination of fruit, vegetable and green tea extracts selected for their established vascular benefits.*
Unlock Your Vascular Vitality
Discover the world's premier supplement for supporting your endothelial glycocalyx, the delicate inner lining of your vascular system. With each 60-capsule bottle offering a one-month supply at recommended doses, your path to vascular wellness has never been more accessible.
The Effects
Daily life feels easier when circulation is strong. Nitric oxide helps blood vessels relax, allowing oxygen and nutrients to reach the muscles, brain, and heart more efficiently. That means less fatigue climbing stairs, steady focus at work, fast recovery after activity, and deep, more restorative rest.*
Nitric oxide is important every hour of the day or night, because your body continuously transports nutrients and removes waste whether you are at work, on your daily walk, or even in your sleep.
In an open-label, published study, a single dose of Vascanox HP increased salivary nitric oxide levels for up to 24 hours.† The unique multi-pathway formula supports nitric oxide production, storage, and delivery for daily vitality and to support long-term cardiovascular resilience.*
Arterosil HP:
Supports a healthy heart
Supports vascular integrity and healthy circulation, helping blood move where it’s needed
Helps maintain healthy arteries, supporting cardiovascular resilience over time
Strengthens the endothelial glycocalyx, the body’s vascular foundation, critical for energy, endurance, and healthy aging
As the cardiovascular evidence and guidelines have evolved, I find myself using Arterosil HP in a more expansive patient base. I am initiating therapy sooner than I might have a few years ago, and Arterosil HP is not an optional supplement, but a necessary supplement. So, now more than ever, as a vascular key opinion leader, I use Arterosil HP as if it belongs in the water.

The Science
Why the Glycocalyx Changes Everything We Know About Vascular Health
The endothelial glycocalyx (EGX) is a delicate, micro-thin lining that coats the inside of every blood vessel in your body. Only recently discovered and often overlooked, it is foundational to vascular health and total-body vitality.
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.
Ingredients
Thoughtfully sourced, quality controlled, vegan
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.*
To enhance its effects, Arterosil HP includes a blend of fruit, vegetable, and green tea extracts selected for their antioxidant and vascular-supportive properties.* These compounds complement the glycocalyx-regenerating activity of MonitumRS.
Every batch of Arterosil HP is produced under Calroy’s Total Quality System, with strict compliance to FDA-defined current Good Manufacturing Practices (cGMP). Batch and test records are maintained to ensure guaranteed purity, potency, and quality.

Because Arterosil HP® works at the structural level to support the glycocalyx,* its effects build over time even when the effects aren't physically noticeable. We recommend regular vascular screening with your healthcare provider to confirm benefits.
Are there any side effects or interactions?
Are there any side effects or interactions?
