The Effects
When circulation is robust, everyday activities feel much easier. Nitric oxide encourages blood vessels to relax, enabling oxygen and nutrients to reach your muscles, brain and heart with greater efficiency. This translates to less fatigue when climbing stairs, consistent focus during work, quicker recovery after physical activity, and deeper, more rejuvenating rest.*
Nitric oxide remains vital around the clock. Your body keeps delivering nutrients and clearing waste nonstop — whether you are working, taking a daily walk, or asleep at night.
According to a published open-label study, one serving of Vascanox HP elevates salivary nitric oxide levels for as long as 24 hours.† Its distinctive multi-pathway formula aids nitric oxide creation, storage and delivery. It boosts daily vitality and supports long-term cardiovascular resilience.
My practice is focused on prevention and I routinely discuss optimizing nitric oxide with my patients. Cardiovascular health cannot be well managed without having optimal endothelial function. When lifestyle interventions alone do not optimize endothelial health then it is useful to add targeted supplement support.

Arterosil HP:
Why the Glycocalyx Changes Everything We Know About Vascular Health
The endothelial glycocalyx (EGX) is a delicate, ultra-thin lining covering the interior of every blood vessel throughout your body. Only recently identified and frequently overlooked, it serves as the foundation for vascular wellness and whole-body vitality.
When the glycocalyx becomes damaged, circulation suffers, and every organ in the body is impacted. Preserving this structure is key to maintaining robust blood flow, cardiovascular wellness, and full-body vitality.
Scientists only recently identified the endothelial glycocalyx, yet it is now acknowledged as one of the body’s most vital structures for human health.
This microscopic gel-like lining carries out many essential tasks to maintain healthy, supple, and robust blood vessels.
Given its essential role in supporting heart and vascular wellness, protecting the endothelial glycocalyx stands as a core focus of contemporary vascular research.
With all of the emerging research on the importance of the glycocalyx for blood-brain barrier integrity, I use Arterosil HP as an essential foundational component for my work in cognitive health.

Arterosil HP® Professional promotes a healthy vascular system*
Featuring a distinctive formula and thoughtfully chosen ingredients, this supplement makes an excellent addition to your daily wellness regimen. It supports healthy circulation, optimal arterial function, and heart health, while helping preserve healthy arterial walls. Arterosil HP® Professional serves as a foundational support for total-body wellness.
Why Support Endothelial Glycocalyx?
Identified only in recent decades, the endothelial glycocalyx (EGX) holds the key to vascular wellness. It acts as a primary upstream target for maintaining healthy blood vessels. Because the vascular system nourishes every organ and bodily system, supporting EGX carries powerful potential for lifelong health and wellness.
Ingredients
Carefully sourced, quality-tested, vegan
Arterosil HP features the exclusive patented ingredient MonitumRS, a rhamnan sulfate extract sourced from rare Pacific green seaweed harvested sustainably. Rhamnan sulfate is a potent glycocalyx-regenerating compound (GRC). MonitumRS aids in repairing and preserving the endothelial glycocalyx, supporting circulation, vascular integrity, and the wellness of all organs and bodily systems.*
To amplify these benefits, Arterosil HP contains a blend of fruit, vegetable and green tea extracts chosen for their antioxidant and vascular-supporting benefits.* These ingredients work alongside MonitumRS to boost glycocalyx regeneration.
Each batch of Arterosil HP is manufactured under Calroy’s Total Quality System and follows FDA current Good Manufacturing Practices (cGMP). Batch documentation and testing records are retained to consistently deliver guaranteed purity, potency and quality.
Frequently Asked Questions
How soon will I notice results?
How soon will I notice results?
Some people report improvements in circulation and energy within weeks, while others notice benefits more gradually. 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?
If you have specific medical conditions or take prescriptions, we recommend speaking with your healthcare provider before adding any supplement to your routine. Arterosil HP is generally well tolerated. In most cases, it can be taken alongside other supplements or medications.
