Generally, seaweed contains high ash content indicating appreciable amounts of minerals. Mineral content of seaweed can account for up to 36% of its dry mass and mineral macronutrients include sodium, calcium, magnesium, potassium, chlorine, sulfur, and phosphorus whereas the micronutrients include iodine, iron, zinc, copper, selenium, molybdenum, fluoride, manganese, boron, nickel, and cobalt. Among these minerals, calcium holds 4-7% of dry matter. At 7% calcium, a t) ical daily portion size of seaweed (8 g dry weight) provides 560 mg of calcium which is a considerable amount compared to its recommended daily allowance (800-1000 mg) (Anonymous, 2004). In seaweeds, calcium is available as calcium phosphate, and that is more bioavailable than the form of calcium in milk, which is calcium carbonate.
