The birth of nutritious food seaweed


For more than two decades, Seagreens® has turned a simple idea into reality.

The idea was to make it easy for anyone to get at least a gram of the most nutritious seaweeds into our daily food. 

Enough to fill significant nutrient gaps in our modern diet, especially the many deficient micronutrients essential for immune function and which help delay the onset of degenerative diseases.

In Norway and Scotland, we pioneered Europe's first harvesting of seaweed specifically for human nutrition at an affordable daily cost.

Today Seagreens® native wild seaweeds, their production supervised to the world's highest standard (NFS - Nutritious Food Seaweed), feed millions of people and are valuable exports worldwide.

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

Your interest in what we do and your daily use of Seagreens® - everyday nutrition products that anyone can simply add to their daily food and drink - has made this project the world's leading producer of seaweeds for human nutrition. 

In this 20th anniversary article published in 2018, Seagreens' founder explains how Seagreens will continue to develop the unique partnership between its brand, its international consortium partners, and its customers around the world for years to come.

The latest of his articles in this series, published in Star & Furrow to celebrate our 25th anniversary, explains the rationale for Nutritious Food Seaweed and the continuing development of seaweed production standards.

In 'Something for Everyone' the rising tide of seaweed for nutrition and health is explored in this 30 minute film show with Saint-Saëns 'Aquarium' music.
