Description
Bladderwrack (Fucus vesiculosus) is a brown seaweed traditionally used in European herbal medicine and coastal diets. It is naturally rich in iodine, fucoidans, and polyphenols that support thyroid function, metabolic balance, and antioxidant defense. Bladderwrack has been valued for easing joint stiffness, promoting skin health, and nourishing the body with trace minerals. Consumed as food or supplement, it remains one of the earliest documented seaweeds in Western herbal practice and continues to be studied for metabolic and immune support.
