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). 


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. It is also recognized as a source of other naturally occurring minerals such as iron, zinc, magnesium, and potassium.


Active Constituents of Bladderwrack



Contraindicated: Do not use this herb in hyperthyroidism (unless under the guidance of a trained practitioner) or if there is excessive circulating iodine. Iodine is capable of entering breast milk and producing an emaciating effect on infants.  This has made some people feel that sea weeds including Bladderwrack should be used cautiously when breast feeding and there has also been some concern during pregnancy.
