Bladderwrack + T4 precursors

while the laminaria species of kelp usually are highest in Iodine content, the bladderwrack species of kelp (fucus spp)is higher in Iodine bound to tyrosine, which is the precursor to the critical T4 thyroid hormone.

Much of the Iodine in bladderwrack presents as di-iodotyrosine(DIT) , an immediate precursor of the thyroid hormones Thyroxine (T4, made from two condensed DIT molecules by thyroid peroxidase in the thyroid follicles) and tri-iodothyronine (T3, made from the condensing of one DIT and one MIT).This makes Fucus spp the sea vegetables of choice for treating thyroid disorders by providing the immediate precursors for T4 and T3. Indeed, Fucus seems particularly effective in treating early stage hypothyroidism. Positive results have obtained in both hypothyroidism and Graves' hyperthyroidism cases.
