Arterosil is owned and distributed by Calroy, a company dedicated to science-based innovations that transform human health with natural solutions. Arterosil, a patent-pending nutraceutical, is the only product in the world that has been clinically proven to rebuild the endothelial glycocalyx. Arterosil contains specialized sulfated polysaccharides (SSPs) derived from a rare seaweed. Certain SSPs rich seaweeds are glycocalyx regenerating compounds (GRC) and have been reported to possess anticoagulant and antithrombotic activity13. The SSP 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.
