The birth of a human food quality seaweed ingredient

Over the past two decades, Seagreens® has turned a simple idea into a reality.

The idea was for all of us to get at least a gram of the most nutritious seaweed into our daily diet. 

Enough to fill significant nutritional gaps in the modern diet, especially the deficient micronutrients.

In Norway and Britain, we pioneered Europe's first harvesting and production of seaweed ingredients for human nutrition, at an affordable cost.

Today we harvest our uniquely certified wild seaweeds in remote locations where the total process from seaweed selection to final product is supervised to the world's highest standard, sending valuable exports overseas.


2018 is Seagreens' 20th Anniversary and it began with a Superfoods Best All Essential Supplement Award in January, for Seagreens® Food Granules and Capsules and our Culinary Ingredient.

It is your interest in what we do and how we do it, and your daily use of our products which has made Seagreens® the leading producer in the world of nutritious food seaweed ingredients.

Thank you from every member of our international consortium, from ocean harvesting to markets around the world. 


This 10th-anniversary article appeared in 2008 in Star & Furrow, the journal of the Biodynamic Agricultural Association.
