Arterosil vs. Endocalyx:
Which One Is Right For You?

The two leaders in Glycocalyx support. Do you need Rhamnan Sulfate or Fucoidan?

Head-to-Head Comparison
Core Ingredient Arterosil HP
MonitumRS™ (Rhamnan Sulfate)
Source: Green Seaweed
Endocalyx Pro
Fucoidan + Hyaluronic Acid
Source: Brown Seaweed
How It Works Mimics the Structure
Acts like a "liquid patch" to fill in gaps in the lining.
Stops the Breakdown
Blocks the enzyme that eats the lining (heparanase) and provides building blocks for repair.
Primary Goal Stabilizing plaque and improving blood flow. Increasing the number of small capillaries (micro-vessels).
Best For People with high cholesterol or soft plaque. People with poor circulation, cold hands/feet, or high blood sugar damage.

The Science of Arterosil (Rhamnan Sulfate)

Arterosil uses Rhamnan Sulfate, a rare seaweed extract that looks chemically identical to the structure of your glycocalyx.

When your blood vessel lining gets damaged, it's like a non-stick pan getting scratched. Arterosil acts like a patch, filling in those scratches. This helps restore the smooth surface of your arteries, which protects them from cholesterol sticking and helps them widen to improve blood flow.

The Science of Endocalyx (Fucoidan & HA)

Endocalyx Pro takes a different approach. It uses a blend of Fucoidan and Hyaluronic Acid.

Fucoidan works by stopping the enzyme that chews up your lining. Think of it as putting up a shield. At the same time, the Hyaluronic Acid provides the raw materials your body needs to rebuild the mesh. It's designed to protect what you have while giving you the bricks to build more.

The GRN Labs Verdict

Different Tools for Different Jobs

Arterosil is great for repairing the structure (like fixing a pothole). Endocalyx is great for protecting the structure and supporting the smallest capillaries.

If you have high risk factors, relying on just one pill might not be enough. The most effective protocols often combine strategies to address both inflammation and repair.

Common Questions

Which is better, Arterosil or Endocalyx?

It depends on your goal. Arterosil is often preferred for stabilizing plaque and improving artery function. Endocalyx is often used for general micro-circulation support (capillaries). At GRN Labs, we look at your specific biomarkers to decide.

Do these supplements really remove plaque?

They do not "scrub" away hard calcium. However, Arterosil has shown promise in stabilizing soft plaque (the dangerous kind) by healing the lining over it, which prevents more cholesterol from getting into the wall.
