fucus vesiculosus

Fucus vesiculosus is a type of brown seaweed commonly known as bladderwrack. It grows in the Baltic Sea, Atlantic Ocean, and North Pacific Ocean. The whole plant is used medicinally and as a dietary supplement. Fucus vesiculosus contains varying amounts of iodine and fucoidan (a sulfated polysaccharide), which are thought to contribute to its biological effects. Iodine from Fucus vesiculosus may help prevent or treat some thyroid disorders by supporting thyroid hormone synthesis; it also has been suggested to have antidiabetic effects and influence hormone levels[1][2][4]. Fucoidan extracted from this seaweed has demonstrated potential benefits for immune health and gut/digestive health[6]. However, there is insufficient scientific evidence supporting its effectiveness for these uses[1][2]. It is primarily marketed as a dietary supplement ingredient rather than an approved pharmaceutical drug.
