The main types in food and supplements are kelp\/kombu (Laminaria\/Saccharina), wakame (Undaria pinnatifida), nori (Pyropia\/Porphyra), dulse (Palmaria palmata), arame (Eisenia bicyclis) and Irish moss (Chondrus crispus).\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn Asian food traditions — especially in Japan, Korea and China — seaweed has been an everyday ingredient for thousands of years. Sushi rice rolled in nori, kombu in dashi soup, wakame in miso soup. On the Atlantic coasts of Ireland and Brittany, people know Irish moss ('sea moss'), a red seaweed traditionally used in puddings and drinks. For Western cuisine, seaweed is a relatively recent discovery, but growth is strong — both as a culinary ingredient and as a supplement category.\u003c\/p\u003e\n\u003cp\u003eWhat sets seaweed apart nutritionally is its combination of iodine and minerals. It is by far the most concentrated natural source of iodine — kelp can contain up to 8,000 µg of iodine per gram of dry weight, while the RI is 150 µg\/day. That makes seaweed intake a double-edged matter: a rich food source, but also an easy way to exceed the UL (upper limit) — especially with kelp and kombu.\u003c\/p\u003e\n\u003cp\u003eFor those considering seaweed, there are three points to watch. First: iodine content varies greatly by type. Second: avoid hijiki because of its arsenic content (advised against by the \u003ca rel=\"noopener noreferrer\" href=\"https:\/\/www.nvwa.nl\/onderwerpen\/voedingssupplementen\/risico-s-voedingssupplementen\" target=\"_blank\"\u003eNVWA\u003c\/a\u003e (Dutch food safety authority) and the UK Food Standards Agency). Third: B12 for vegans is complicated — many seaweeds contain pseudo-B12 that the human body does not recognise as active B12.
