Fucus (vesiculosus, serratus) are primarily used as additives in the diets (impact of fucans + iodine), specifically when obesity is accompanied by hypothyroidism (soft, pale and chilly overweight). There are natural medications that are created of thallus of Fucus powder (that contains 20 to one hundred twenty micrograms of iodine per gram), alcoholic extract of fucus (one hundred ten micrograms of iodine per 10 ml) and a homeopathic mother tincture. An average dose is .five to 1 g of powdered thallus per day or a hundred to one hundred fifty drops of mom tincture. Be watchful not to exceed a hundred and twenty micrograms of iodine for each day.
