Founded in 2005, OceanHarvest Botanicals has deep roots in Cornwall's coastal communities. What started as a small seaweed harvesting operation has grown into one of the UK's most trusted fucoidan suppliers. Their secret? A commitment to sustainable sourcing. They work directly with local fishermen and seaweed farmers who use hand-harvesting methods to protect marine ecosystems. "We believe the best fucoidan comes from healthy oceans," says their founder, Emma Green. "That's why we only source from areas with strict environmental protections."

OceanHarvest offers a range of products, including bulk fucoidan powder (starting at 1kg orders) and organic fucoidan extract, perfect for supplement manufacturers and cosmetic formulators. All their products are certified organic by the Soil Association and undergo rigorous third-party testing for purity and potency. Customers rave about their consistent quality—one skincare brand noted, "Their fucoidan extract blends seamlessly into our serums, and we've seen a noticeable improvement in customer feedback about skin hydration."

What sets them apart? Their "Trace My Seaweed" program, which lets customers track the origin of their fucoidan batch, from harvest location to extraction date. For businesses prioritizing transparency, this is a game-changer.

Nestled in the heart of Edinburgh, British Algae Extracts Co. has built a reputation for innovation since 2010.
