From: The emerging science of gastrophysics and its application to the algal cuisine

Nutrients in seaweeds Composition
Proteins, essential amino acids 7% to 35%
Dietary fibres (soluble, insoluble) 45% to 75%
Vitamins A, B (B1, B2, B3, B6 and B12 of folate), C, E
Iodine Variable large amounts in some brown species
More K+ salts than Na+ salts  
   Minerals Fe, Ca, P, Mg, Cl
   Trace compounds Zn, Cu, Mn, Se, Mb, Cr
   Essential fatty acids (2% to 5%), ω-3 (EPA, no DHA), ω-6 (AA)
  1. aAA, arachidonic acid; DHA, docosahexaenoic acid; EPA: eicosapentaenoic acid. The actual composition depends very much on the species, its age, the location of growth and the time of harvesting [34, 3645]. Percentages refer to dry weight.
