Support your thyroid with sea vegetables

By Juliana Kassianos, Transformational Fertility Coach, Yoga Teacher and Founder of The School of Fertility


Sea vegetables are mineral-rich, particularly in iodine, which is important for thyroid function, as it is one of the building blocks for the production of thyroid hormones. An underactive thyroid can affect ovulation and increase the risk of pregnancy complications, so it is important to have a healthy functioning thyroid.

NB. Iodised salt, which is table salt combined with a tiny amount of various salts of iodine is usually highly refined and may also contain sugar. Sea vegetables, however, are a good natural nutritional source of iodine.


Seaweeds are a good source of some water-soluble vitamins such as B1, B2, B12, C and fat-soluble vitamins such as β-carotene (precursor of vitamin A) and vitamin E.


Seaweeds have been shown to be rich in antioxidants.
