Our Sea-Vegetables Powder is a blend of equal parts dulse, wakame and kelp, all harvested off the coast of Maine. They are certified organic and are thoroughly tested for any trace of contamination by such things as heavy metals and radiation. It has a more "oceanic" flavor than our mild Nori Powder, and it's packed with vital nutrients. Dulse, a kind of red algae, has been used in Europe for at least 1,500 years, and there is a reference in a Chinese health manual from 600 BC about the necessity of feeding red dulse to the Chinese kings to insure their longevity.   Dulse is rich in such minerals as iodine for thyroid support, chromium for blood-sugar regulation and manganese for supporting healthy bone formation.
