Does spirulina contain iodine? Can hyperthyroidism patients eat?

Spirulina has become a new food for people to supplement iodine because of its rich iodine.

It is very important to control iodine while treating hyperthyroidism. Spirulina and other seafood contain high iodine, which easily leads to the increase of thyroid hormone and leads to ineffective treatment. Fasting should be done, even in the maintenance stage after hyperthyroidism is cured.
