I found this information ahoney, I daresay it is available in health shops.
Dulse seaweed is a natural treasure chest of goodness, with Vitamins A, B1, B2, B3, B6, B12, C, and E, and minerals like potassium, calcium, magnesium, phosphorous, chromium, iodine and zinc and trace elements.
Suggested Uses
Enjoy Dulse Leaf straight out of the bag, or sprinkle Leaf or Flakes in soups, stocks, stews, miso, stirfrys or savoury dishes. Alternatively, use to ‘salt' pasta or potato boiling water.
