Arterosil HP

Protect the Glycocalyx. Support Heart & Vascular Health* 

By targeting the foundation of your vascular system, Arterosil HP is more than support - it's the gold standard for heart health.* Arterosil HP® uniquely contains MonitumRS®, which is scientifically shown to protect and restore the endothelial glycocalyx,*† the fragile inner lining of every blood vessel. A healthy endothelial glycocalyx is required for healthy circulation. Foundational to circulation, cognition, and resilience, it addresses what others overlook in just one capsule, twice daily.

†As demonstrated in an independent third-party laboratory in vitro study.

The Effects

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.

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.

Arterosil HP

As I’ve watched the powerful impact that using Arterosil HP has had in some of my most difficult cases, it’s really broadened my perspective on who and what I might want to use it for.

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?

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?

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.
Who should consider Arterosil HP?

Arterosil HP is intended for anyone looking to support cardiovascular and vascular health, especially those focused on circulation, heart health, or healthy aging.*
What's the best protocol for vascular health?

For foundational vascular wellness, Arterosil HP with MonitumRS is commonly paired with Vascanox HP® with Noxa24® to support both glycocalyx integrity and nitric oxide production.*
