Product Introduction
Bladder Wrack Extract – Premium Marine Botanical Ingredient
Kingherbs Limited uses verified titration and UV/HPLC to manufacture pharmaceutical-grade Bladder Wrack Extract standardized to Fucoidan 10–50% and Iodine 0.08–0.4%. Our extract preserves heat-sensitive fucoidans and phlorotannins from verified Northern Atlantic Fucus vesiculosus harvest zones using pure water or food-grade ethanol and no harsh solvents. All batches undergo ICP-MS heavy metal screening for inorganic arsenic < 2 ppm, lead < 3 ppm, and mercury < 0.1 ppm. Our 95% pass-through 80-mesh powder ensures consistent formulation of thyroid support supplements and metabolic complexes with steady iodine concentration (±0.02% tolerance) and high water solubility. Ready stock allows 3–5-day global shipping.
What is Bladder Wrack Extract?
Fucus vesiculosus, a brown seaweed found in chilly oceans, provides this natural element. Organic iodine, fucoidans, and phlorotannins are present.
Our product iodine produces thyroid hormones. Hormones regulate calorie burning speed. The extract provides nutrients and beneficial ingredients for general health.
This marine extract contains protein-bound iodine, unlike synthetic. This type is safer and easy to digest.
