The seaweed also had another, yet undiscovered, important chemical. One day towards the end of 1811 while Courtois was isolating sodium and potassium compounds from seaweed ash, he discovered iodine after he added sulfuric acid to the seaweed ash. He was investigating corrosion of his copper vessels when he noticed a vapor given off.
Bladder wrack is named for its conspicuous vesicles. Fucus vesiculosus, known by the common names bladderwrack, black tang, rockweed, sea grapes, bladder fucus, sea oak, cut weed, dyers fucus, red fucus and rock wrack, is a seaweed found on the coasts of the North Sea, the western Baltic Sea and the Atlantic and Pacific Oceans.

Their protein content is low and their heavy metal content is high, especially for arsenic and iodine, which are respectively toxic and nutritious. [36] [37] They are valued for fish production. [38] Adding seaweed to livestock feed can substantially reduce methane emissions from cattle, [39] but only from their feedlot emissions. As of 2021 ...
Iodine in the ocean exists mostly in oceanic sediments and seawater. [4] During subduction of oceanic crust and seawater, most of the iodine cycles into seawater through brine, while a minor amount is cycled into the mantle. [4] Marine biota, including seaweed and fish, accumulate iodine from the seawater and return it during decomposition. [2]
Researchers have found that eating antioxidant-rich seaweed may stave off the devastating ... Rich in iodine and antioxidants seaweed supports thyroid health and can protect the body from free ...
The species Saccharina latissima yielded the greatest amount of iodine (between 10 and 15 lbs per ton) and was most abundant in Guernsey. Iodine was extracted from kelp ash using a lixiviation process. [42] As with sodium carbonate however, mineral sources eventually supplanted seaweed in iodine production. [43]
On the observation that Japanese women who consume iodine-rich seaweed have a relatively low rate of breast cancer, iodine is suggested as a protection against breast cancer. [64] [65] Iodine is known to induce apoptosis in breast cancer cells. [66]
