Pure Ulva.
Nordic origin.

Sea lettuce isn't an invention. People along the Nordic coastline, the British Isles, and East Asia have eaten it for thousands of years. We haven't tried to make something new of it. Just to leave it as it is.

Pure Ulva is Ulva fenestrata, cultivated in clean, cold waters off Sweden's west coast. Dried, milled, and encapsulated. Nothing added. Nothing extracted. What we offer is the sea lettuce itself, in a capsule.

What a daily dose gives you

Each daily dose delivers a high content of iodine and is a source of vitamin B12. Both naturally present in the seaweed itself.

• Iodine contributes to normal thyroid function, normal cognitive function, and normal energy-yielding metabolism.
• Vitamin B12 contributes to the reduction of tiredness and fatigue, normal energy-yielding metabolism, and normal function of the nervous system.

Whole seaweed, not extract

Pure Ulva is the dried whole plant. Beyond the iodine and B12, sea lettuce naturally contains dietary fibre, plant protein, marine minerals including potassium, magnesium and iron, naturally occurring fatty acids including omega-3, and the green plant pigments such as chlorophyll that give sea lettuce its colour.

These are part of the seaweed itself. We don't isolate them. We don't concentrate them. We make no claims about what we haven't measured. What we measure and document, we publish.

Where it comes from

Our seaweed is grown by Nordic SeaFarm in Bohuslän on Sweden's west coast, in cold, clean waters with a steady tidal flow. It's gently dried at low temperature, milled into a fine powder, and encapsulated.

Documented, batch by batch

Every batch is independently analysed at an accredited laboratory. We document nutritional content, heavy metals, and microbiological safety. The Certificate of Analysis for your specific batch is available on request.

Most algae supplements have little or no batch-level documentation. That's the difference between selling a product and standing behind it.

Who it's for

Pure Ulva is suitable for adults who want a documented source of iodine and B12 in their daily routine. Especially:

• People following plant-based or vegan diets, where B12 intake is often a concern
• People who don't regularly eat seafood, dairy, or iodised salt
• People who prefer whole-food supplements over isolated synthetic vitamins

Vegan. Gluten-free. GMO-free. One species, one supplier, fully documented.
