Marine collagen
from fish bone

The first of its kind.

Every marine collagen on the market is derived from fish skin. We've developed proprietary technology to extract collagen peptides from wild-caught fish bone – delivering a richer collagen profile, natural mineral synergy, and a fundamentally cleaner source.

The difference

Why fish bone matters

Fish bone skeleton – the raw material behind our collagen
01

Richer collagen profile

Fish bone contains collagen types I, VI, XI, and XXII – a diversity that fish skin simply cannot provide. These specialized types work in concert to support joint integrity, bone structure, and connective tissue health.

02

Natural mineral synergy

Fish bone naturally combines collagen with calcium, phosphorus, and magnesium. Research shows these minerals are significantly more effective at strengthening bone when delivered together with collagen peptides.

03

Cleaner source

Wild-caught, fully traceable, and free from any land animal. Halal, kosher, and pescatarian friendly – without the BSE risk and contamination concerns associated with bovine collagen.

Research-backed

The science behind it

Fish bone collagen isn't just different in origin – it's different in how it works. Here's what the research shows.

1.5×

Superior absorption

Marine collagen peptides are absorbed up to 1.5 times more efficiently than bovine collagen, reaching target tissues faster and at higher concentrations.

+200%

Enhanced calcium uptake

Fish bone collagen contains unique calcium-chelating peptides that can enhance intestinal calcium absorption by up to 200% – a mechanism entirely absent in skin-derived collagen.

2-in-1

Dual-action bone support

The peptides stimulate bone-building cells while simultaneously suppressing bone-degrading cells – actively shifting the balance toward bone formation and increased mineral density.

More than an ingredient. A better source.

Use cases

Circular economy

From sidestream
to solution

We process underutilized, high-value marine sidestreams into premium collagen peptides. Every batch starts with fish bone that would otherwise go to waste – turning a byproduct of the fishing industry into a traceable, high-performance ingredient.

Upcycled from fishing industry sidestreams

Wild-caught, sustainably sourced

Fully traceable supply chain

European origin, processed in Denmark

About us

A Danish biotech startup

We're a Danish biotech company developing proprietary processing technology to extract collagen from fish bone – something the industry hasn't done at scale before.

We believe great partnerships start with a conversation. We'd love to show you our process, walk you through the science, and explore how fish bone collagen fits your product line.
