The Science

The Endothelial Glycocalyx

Image of an Artery

Breakthroughs in scientific knowledge have brought a critical structure to the fore: the endothelial glycocalyx. This slippery, micro-thin inner lining of every blood vessel in the body performs many important functions, including:

  • Supporting the health of the endothelium
  • Harboring antioxidants, coagulation factors, and more
  • Regulating passage of molecules through to the endothelium
  • Triggering nitric oxide production and resulting vasodilation

The endothelial glycocalyx supports every blood vessel in the body. That’s hugely important for your vascular system. And of course, every organ in your body depends on healthy blood flow.

"The endothelial glycocalyx [is] really one of the most important and intensely researched areas in human health in years."

The Ingredients

Thoughtfully Sourced, Quality Controlled, Vegan

Arterosil HP® uniquely contains MonitumRSTM – 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 (GRC). The fruit and vegetable blend in Arterosil HP has important antioxidant properties that support the effects of MonitumRSTM by reducing oxidative stress.*

To create Arterosil HP, MonitumRSTM is enhanced with an added combination of fruit, vegetable and green tea extracts selected for their established vascular benefits.* The product is assembled using a Total Quality System, which includes strict compliance with cGMP’s current good manufacturing practices as defined by the United States Food and Drug Administration. 

Batch and test records are maintained throughout the manufacturing process to ensure the guaranteed quality of the final product.
