Arterosil
Arterosil contains rhamnan sulfate, a specialized sulfated polysaccharide derived from the green seaweed Monostroma nitidum. Rhamnan sulfate is a glycocalyx regenerating compound (GRC) and has been reported to possess anticoagulant and antithrombotic activity13.
The rhamnan sulfate found in Arterosil has a similar chemical structure to heparan sulfate found abundantly in human endothelial glycocalyx, and may exert its biological activities by regenerating endothelial glycocalyx.
Arterosil is available exclusively through licensed health care practitioners. Manufactured in the USA, Arterosil currently ships to the 50 United States and Puerto Rico only.
Structure of endothelial glycocalyx and its activation of vascular muscle relaxation via nitric oxide (NO) in response to increased shear force3,6
The endothelial glycocalyx is a microscopically thin gel-like layer that coats the entire luminal side of the vascular endothelium. It is the key to endothelial health because it prevents cholesterol and other particles from adhering to or penetrating the endothelial wall.
Its functions in vascular and micro-vascular health include:
- Regulates vascular permeability and fluid balance due to the large size and negative charge of its glycosaminoglycans2,3
- Provides a physical barrier against inadvertent adhesion of platelets and leukocytes to the vascular wall4
- Regulates coagulation as many of mediators of coagulation pathway are buried inside the glycocalyx under normal physiological condition5
- Functions as a mechano-sensor and transducer of the shear-force inside blood vessels to regulate the synthesis of nitric oxide (NO) in response to the blood flow3,6

Glycocalyx Damage and Associated Pathologies
The endothelial glycocalyx is a delicate structure and can be damaged under many conditions. The primary contributors to breakdown of the endothelial glycocalyx are high blood glucose, oxidative stress and inflammation. Pathologies associated with impaired endothelial glycocalyx include:
- Coronary heart disease7
- Hyperglycemia8
- Diabetes9
- Renal diseases10
- Lacunar stroke11
- Severe trauma12
