Our Unique Formulation for Arterosil HP

With MonitumRS®

Arterosil HP® uniquely contains MonitumRS® – a proprietary extract of rhamnan sulfate, a specialized sulfated polysaccharide derived from the rare green seaweed, Monostroma nitidum.

Calroy’s unique formula is based on years of experience and research, and MonitumRS is only available in Arterosil HP.

MonitumRS comprises a full-spectrum extract of rhamnan sulfate (RS) from Monostroma nitidum, a rare green seaweed harvested in the Pacific Ocean. MonitumRS is scientifically shown to protect and restore the endothelial glycocalyx.†

Independent Research Studies

For the past thirty years, rhamnan sulfate from Monostroma nitidum has been the subject of significant scientific research, primarily focused on cardiovascular health. Several independent studies have been conducted by major research institutions, establishing a number of key benefits to the human vascular system. See more.

One of the most important findings is that rhamnan sulfate from Monostroma nitidum:

  • Supports the endothelial glycocalyx (EGX), the inner lining of every blood vessel, which helps maintain the entire endothelium and helps regulate many of its key functions

In addition, rhamnan sulfate from Monostroma nitidum has been shown to:

  • Enhance the barrier function of the EGX
  • Reduce vascular oxidative stress
  • Support arterial health
  • Support normal gut function

In a novel microfluidic chip study by the Chinese Academy of Sciences, rhamnan sulfate from Monostroma nitidum had powerful effects on protecting and supporting the endothelial glycocalyx. See manuscript.

Proprietary Extraction for Optimal Quality

To ensure its pristine quality, Monostroma nitidum is sustainably wild harvested for Calroy Health Sciences. Additionally, our seaweed is independently tested to ensure that it does not include:

  • Heavy metals
  • Pesticides
  • Radioactivity
  • Bacteria
  • Fungi

The resulting ingredient, MonitumRS, is extracted according to a proprietary process for inclusion in Arterosil HP. The full-spectrum rhamnan sulfate in MonitumRS is unique to Arterosil HP. The extraction process is time-tested and results in a highly potent product, as Calroy’s research has demonstrated.

Because rhamnan sulfate is a complex sulfated polysaccharide with many molecular configurations, extraction is a technical challenge — one which Calroy Health Sciences has taken on to bring this product to market. Ensuring that the rhamnan sulfate is extracted properly leads to the reliable results seen in Calroy’s research.
