Seaweeds are highly nutritious foods, containing large amounts of minerals and trace elements, including iron, calcium and iodine, as well as vitamins A, C and B complex.

Due to their dense mineral content sea vegetables are advantageous even when consumed in small quantities. Sea vegetables are beneficial for the thyroid, bones, teeth, hair, skin and nails, for lowering cholesterol and decreasing fat in the blood, for weight loss, for rejuvenating the lungs and the gastrointestinal tract, and for removing radioactive and toxic metals from the body, just to name a few. In addition to being some of the most nutrient-rich foods in the world seaweeds are also extremely low in kilojoules.
