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.

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

Beyond
the product.
Pure Ulva is the crop we farm in the sea. Terralgea Restore is what we give back.
Same species, same supplier. But here the goal is different: rebuilding marine environments where the ocean has receded.
We think a premium product should give the sea back more than it uses. That's an ambition that takes time to live up to, and that's exactly the point.
In dialogue with authorities and municipalities on a controlled pilot.
Terralgea Restore is led by Siv Langøy, who works to give the coast back what it has lost.

From the founder
Why Terralgea exists.
«Supplements are often sold on big words. We build Terralgea on the opposite: one ingredient, Nordic origin, and documentation that can be verified, batch by batch.
Pure Ulva is the start. The goal is a business that gives the sea more back than it takes.»
