*Cysteine is a non-essential methionine amino acid derivative formed in collaboration with vitamins B6 and B12 whereas cystine, a compound formed when two amino acids form a disulfide bond, is a more stable semi-essential amino acid. Both are important in protein synthesis, detoxification and metabolism and cystine is a substrate for the cystine-glutamate cell transport by which it is readily broken down to cysteine in the cell. Normal human hair and skin contains 10-14% cystine.

*For more iodine information and a comparison of iodine levels in Seagreens products see below 'Iodine levels in Seagreens® nutrition products'. **Silicon and silica are different chemical species, the key difference being that silicon is an element whereas silica is a compound. Higher levels in seaweed may indicate the coincidental collection of sand during harvesting and is indicative of low grade seaweed unlikely to have been produced to standards for human consumption.

Salad & Condiment - Nutritional profile per 100g
Iodine levels in Seagreens products
Iodine variance in commercially available seaweeds

Over the past decade we have built up a unique body of data on the composition of our native wild seaweeds for which there is no academic or commercial parallel.

Typical nutritional values are averages over the past decade. Several times each year, each batch we harvest is comprehensively analysed by the same methods at independent, government accredited laboratories in the UK, USA and EU.

Nothing is added to or extracted from our seaweeds, which are certified to Nutritious Food Seaweed standard by the BDA (UK Biodynamic Association). They are also BRC (British Retail Consortium), Organic, Kosher for Passover, compliant for Halal, Vegan, and non-allergenic for any special dietary requirements, free from any harmful contaminants.

The Seagreens® project has significantly improved nutrient values through its pioneering production with 5 harvesting locations in the British Isles and Nordic region over the past quarter century. That is why leading food and nutrition brands use Seagreens® ingredients in their own products.
