A rich iodine source, sea vegetables can play a role in supporting thyroid function as iodine is a needed precursor for making thyroid hormones. These sea plants may also help prevent cancer by inhibiting the growth of vessels that feed tumor cells and via their lignans, which can block the hormonal signaling of estrogen-dependent cancers. Fucan substances in these plants can decrease inflammation processes in the body. Therapeutic levels of folic acid and magnesium also provide excellent protection for the heart and cardiovascular system, while magnesium and the lignans can be an excellent help for women experiencing menopausal symptoms. Finally, pantothenic acid and riboflavin are B vitamins and very useful in helping someone who has too much stress and anxiety, both of which may deplete these nutrients.
