Bladderwrack is a marine botanical ingredient obtained from Fucus vesiculosus, a species of brown seaweed that grows naturally along the rocky coastlines of the Atlantic and Pacific Oceans. Recognized by the small air-filled bladders along its fronds, this seaweed has been used in traditional coastal diets and herbal wellness practices for centuries.
Today, Bladderwrack is commonly included in dietary supplements focused on mineral nutrition, thyroid wellness, and overall health. It is valued for its naturally occurring iodine, minerals, polysaccharides, and antioxidant compounds, making it a popular ingredient in marine-based wellness formulations.
Bladderwrack is a brown seaweed belonging to the Fucaceae family. It grows attached to rocks in shallow coastal waters, where it absorbs minerals directly from seawater throughout its life cycle.
