Glycocalyx Support (Arterosil-style)
Arterosil · Arterosil HP
The endothelial glycocalyx is a gel-like layer of glycoproteins, proteoglycans, and glycosaminoglycans (GAGs) that lines the entire vascular endothelium. It is essential for vascular function: it senses shear stress and triggers nitric oxide release, prevents leukocyte adhesion (anti-inflammatory), regulates vascular permeability, and protects the endothelial cell layer from damage. The glycocalyx is the FIRST defense barrier of the vascular system - damage to it precedes and drives endothelial dysfunction, atherosclerosis, and microvascular complications.,Glycocalyx degradation is widespread in modern populations, driven by hyperglycemia (diabetes/prediabetes), oxidative stress, inflammation, sepsis, hypertension, and aging. Damaged glycocalyx → exposed endothelium → leukocyte adhesion → atherosclerotic plaque initiation. Restoration of glycocalyx integrity is an emerging cardiovascular intervention target.,Arterosil HP (Calroy Health Sciences) is the most-studied branded glycocalyx-supporting supplement. It contains Monitus, a proprietary blend of rhamnan sulfate (from Monostroma seaweed - structurally similar to heparan sulfate, a key glycocalyx GAG) plus other supportive nutrients. Clinical research has demonstrated improved glycocalyx integrity (measured via PBR - perfused boundary region), endothelial function, and reduced markers of vascular damage. Multiple cardiologists have recommended Arterosil for patients with vascular concerns.
Take with meals to optimize absorption. Typical protocols are 1-2 caps twice daily for 60+ days. Best results may require 6+ months of consistent use. Often combined with omega-3, CoQ10, and other cardiovascular supplements.

How it works
Rhamnan sulfate (the active ingredient in Monitus): a sulfated polysaccharide from Monostroma green algae, structurally similar to heparan sulfate (a key GAG of the natural glycocalyx). It binds to and protects/restores the endothelial glycocalyx, supporting its barrier function and signaling roles.,Glycocalyx restoration: providing exogenous GAG-like compounds may support glycocalyx repair and prevent further degradation. The glycocalyx is constantly turning over (hours to days half-life of components), so continued substrate availability is important.,Anti-inflammatory: a healthy glycocalyx prevents leukocyte adhesion to the endothelium - the first step in atherosclerosis. Restored glycocalyx reduces this inflammatory cascade.,NO bioavailability: glycocalyx damage impairs shear-stress sensing and reduces eNOS activation. Restoring glycocalyx improves nitric oxide signaling, vasodilation, and endothelial function.,Anti-thrombotic: intact glycocalyx provides anti-coagulant properties (heparan sulfate is a natural anticoagulant cofactor). Damaged glycocalyx → pro-thrombotic state.,Microvascular protection: supports capillary integrity in kidneys, eyes, brain - relevant to diabetic complications and microvascular aging.
