The Effects
Health and vitality begin with your vascular system. Healthy circulation supports sharp thinking, steady energy, and the comfort to stay active as you age. At the core is the endothelial glycocalyx, the recently discovered micro-thin gel lining in your veins, arteries, and capillaries. A healthy glycocalyx shields and regulates the entire vascular system. Every heartbeat, every breath, every step relies on blood vessels functioning at their best.
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.
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.
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.

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.
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.
