Bladderwrack Seaweed

Ethically and sustainably wild-harvested by a small company, this Bladderwrack Seaweed from the northern Atlantic U.S. coast is a nutrient-dense, common brown algae.  It’s low-fat and high in Iodine, fiber, vitamins, and minerals; has macro- and micro-nutrients, and is a functional food in several Asian and European countries,  and Alaska.  It is also used for thyroid health and weight-loss, and has many well-researched and documented therapeutic uses.
