Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Angel's hair seaweed, also known as "Angel Hair Algae" or by its scientific name Chondrus crispus (though this term is sometimes mistakenly used for other edible seaweeds), has a traditional reputation in some cultures for supporting thyroid health. The primary basis for this traditional use is the relatively high iodine content found in many edible seaweeds, including Angel's hair. Iodine is an essential micronutrient required for the synthesis of thyroid hormones, and iodine deficiency is a well-known cause of hypothyroidism. As a result, cultures with access to sea vegetables have historically consumed them to support thyroid function, particularly in regions where iodine deficiency in soil and water is common.

However, direct scientific studies specifically investigating Angel's hair seaweed for hypothyroidism are lacking. Most available research has focused on other, more widely consumed seaweeds such as kelp (Laminaria spp.) or nori (Porphyra spp.), which also contain iodine. The evidence for Angel's hair is therefore indirect, based primarily on its iodine content rather than clinical trials or robust scientific validation. Excessive iodine intake from seaweed can also potentially worsen thyroid disorders, so caution is advised.

In summary, Angel's hair seaweed is used traditionally for hypothyroidism due to its iodine content, but scientific evidence specific to this species and condition is limited.
