What is the difference between wild marine collagen and bovine collagen?

Overview
Wild marine collagen and bovine collagen differ significantly in their source, processing, purity, and cost. Landish exclusively offers marine collagen made in Canada from high-purity wild North Atlantic fish skins—a premium, sustainable choice.

Source Material

Bovine Collagen: Made from cattle hides, a byproduct of the meat industry, almost always made in large part from factory-farmed sources.
Landish Marine Collagen: Derived from wild North Atlantic fish skins that would otherwise go to waste, a cleaner, more responsibly sourced raw material.

Processing & Molecular Weight

Bovine Collagen: Requires harsh chemical and enzymatic treatments to break down tough tissues. Even after processing, it retains a higher molecular weight, making it less optimal for absorption.
Landish Marine Collagen: Extracted using gentler methods, resulting in a lower molecular weight that enhances bioavailability while preserving bioactive peptides.

Purity & Sustainability

Bovine Collagen: Often contains hormones, antibiotics, and pesticide or herbicide residues, as it comes from industrial farming.
Landish Marine Collagen: Naturally free of contaminants, with every batch lab-tested for purity, including heavy metals (e.g., mercury tests negative at 0.005 ppm, 100x lower than the Canadian limit for fish). Plus, it upcycles a high-quality byproduct, preventing waste.

Cost Factors

Bovine Collagen: Lower cost due to widely available raw materials and simpler (though harsher) processing, but with lower purity and effectiveness.
Landish Marine Collagen: More expensive due to the limited supply of premium North Atlantic wild fish skins, specifically highly sought-after cod and haddock, as well as specialized clean extraction methods and rigorous purity standards.

Made in Canada

Bovine Collagen: No known Canadian-made bovine collagen sources.
Landish Marine Collagen: Proudly made in Canada.

Conclusion

Landish wild marine collagen stands out for its superior bioavailability, purity, and sustainability. While it comes at a higher price, its quality, ethical sourcing, and clean processing make it a smarter choice than bovine collagen.
