Fucus vesiculosus, known by the common names bladder wrack, black tang, rockweed, 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. It was the original source of iodine, discovered in 1811 and was used extensively to treat goitre, a swelling of the thyroid gland related to iodine deficiency.
Bladderwrack is typically consumed as a tea, taken in tablet form, or added to broths and soups as it adds a salty flavor profile. Bladderwrack contains significant amounts of mucilage, protein, vitamin C and polysaccharides, including fucoidans, fucans and algin. Bladderwrack is also a rich source of natural iodine.
Fucus vesiculosus is sold as a nutritional supplement. Primary chemical constituents include mucilage, algin, mannitol, fucitol, beta-carotene, zeaxanthin, volatile oils, iodine, bromine, potassium, and other minerals.
Bladderwrack is a soothing herb traditionally used to treat reflux and heartburn. Hypothyroidism due to insufficient iodine intake may improve with bladderwrack supplementation. More. Bladderwrack (Fucus vesiculosus) is a type of brown seaweed that contains variable amounts of iodine .
Bladderwrack is used for thyroid disorders including underactive thyroid (myxedema), over-sized thyroid gland (goiter), and iodine deficiency.Bladderwrack contains over 500% NRV Iodine. Iodine supports the Thymus gland and is essential for the production of white blood cells. Iodine is an essential component of the Thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroid hormones regulate many important biochemical reactions, including protein synthesis and enzymatic activity. Iodine therefore contributes to your normal energy yielding metabolism.
In addition to this, Iodine contributes to the normal functioning of the nervous system and to the maintenance of normal skin and normal cognitive function.
Bladderwrack contains natural dietary fibre, which helps to support regular bowel movements. It also contains Fucoidin, which demonstrates antibacterial, antiviral and antifungal properties.
Bladderwrack Benefits for Skin
Bladderwrack has been used as a topical treatment for skin issues, such as cellulite, skin aging, and burns.Early research has shown that the antioxidants in bladderwrack, namely fucoidan, promote collagen synthesis in the skin, which may help improve the look of cellulite, increase skin healing, and delay premature skin aging.In the first phase of a two-phase study, applying bladderwrack extract to skin samples led to a 228% increase in collagen production, compared with no improvements in the control group
Bladderwrack is one of the highest iodine containing sea vegetables known. The iodine in bladderwrack is present in the form of di-iodotyrosine (DIT) which is a normal precursor of the Thryoid Hormones T4 (Thyroxine) and T3 (tri-iodothyronine). T4 is manufactured by the condensing of DIT and thyroid peroxidase enzyme in the follicular luminae of the thyroid gland. The naturally occurring source of iodine makes Bladderwrack a great choice in the support of a healthy functioning thyroid gland when more iodine is required for optimal function. Also of interest is the high amount of fucoidin found in Bladderwrack. Fucoidans and Fucans are sulfated polysaccharides found in most brown seaweeds. These substances have been researched for modulating a healthy inflammatory response, and have shown strong properties for supporting a healthy immune system and intestinal flora. It is also recognized as a source of other naturally occurring minerals such as iron, zinc, magnesium, and potassium.
