Category vs. substance

Green has become a category.
Substance has become an afterthought.

The greens segment has grown faster than the documentation behind it. Origin is often unclear, and documentation usually stops at the label. We do the opposite: one ingredient, Nordic-grown, with documentation that can be verified. We don't compete on price. We compete on what few others can actually document.

Commodity greens

  • Imported, often unclear origin.
  • Blended formulations.
  • No batch documentation.
  • Price-led.

Premium Nordic Ulva

  • Single ingredient. North Sea.
  • Certificate of Analysis per batch.
  • Independently verified at Eurofins.
  • Standards-led, not price-led.

What sets us apart

The product is simple.
The system behind it isn't.

One ingredient

100% Ulva fenestrata in plant-based HPMC capsules. Nothing added to make it cheaper. No blends that hide what the product is.

Nordic origin

Cultivated in the North Sea. Every batch tied to a cultivation site and date.

Full traceability

Every batch tested before release. The documentation exists, and we share it on request.

Selective distribution

Few partners per market. We'd rather be off one shelf than on all of them. The line on quality and price is the same for everyone.

Traceability

From sea
to capsule.

Every capsule traces back to one batch, one analysis, one shipment. No gaps. Plenty claim traceability. We show it.

Marine restoration

Beyond
the bottle.

Pure Ulva is what we take from the sea. Terralgea Restore is what we rebuild.

Same species, same supplier. But here the goal is different: rebuilding marine environments where the ocean has receded.

We think a premium product should rebuild more than it takes. That's an ambition that takes time to live up to, and that's exactly the point.

First pilots in Halden and the inner Oslofjord.
