"Seaweeds contain 10 to 20 times the minerals of land plants, as well as necessary vitamins. And the nutrients in seaweed are much more assimilable (absorbable) than land-plants. Seaweeds are a superb source of iodine, which your glands need to function well (particularly your thyroid gland)."
"In addition, lots of calcium that is easily assimilated, seaweeds contain more than 90 minerals which our bodies need -- and in just the right proportions."
