Bladderwrack

Bladderwrack is the dried whole thallus of Fucus vesiculosus, a brown seaweed of the North Atlantic and Baltic coasts, named for the paired air-filled bladders along its fronds. Nustras supplies it as dried cut thallus, milled powder and extract powder. The seaweed contains iodine, alginates, fucoidan, mannitol and polyphenols, and its iodine content is the usual reason buyers select it.

Bladderwrack is formulated into botanical and mineral supplements in capsule, tablet and liquid form, into seaweed and iodine-category blends, herbal tea mixtures and tinctures, and into functional foods, seasonings and cosmetic body-care products.

Supplied as olive-brown to dark brown cut pieces or a greenish-brown powder with a marine odour and a salty taste. Botanical identity is confirmed by macroscopic examination and the iodine content by titration or ICP; moisture, ash and particle size are standardised to specification. Heavy-metal (including arsenic), pesticide and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies bladderwrack in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Bladderwrack is an accepted food and supplement ingredient in major markets; buyers confirm the iodine contribution and permitted level for their application.
