They work directly with local fishing communities to harvest wild brown seaweed (think sargassum and laminaria) using eco-friendly methods that protect marine ecosystems.
Product Range:
They specialize in bulk fucoidan extract powder (with purity levels from 85% to 98%), as well as liquid extracts for cosmetic formulations. For those new to fucoidan, they also offer small-batch trial sizes, making it easy to test before committing to larger orders.
Quality You Can Trust:
All their products are GMP-certified and undergo third-party testing for heavy metals and contaminants. Customers rave about their consistency—many local supplement brands in Nairobi source their fucoidan supplement raw materials here.
2. GreenWave Fucoidan Traders
Nairobi-based GreenWave Fucoidan Traders might not manufacture their own extracts, but they've built a reputation as one of Kenya's most reliable wholesalers, partnering with top global producers (including some of the best fucoidan made in Japan). This means they can offer a wider range of products than many local manufacturers, from organic-certified fucoidan to specialized extracts for pharmaceutical research.
Why Choose Them?
If you're looking for variety, GreenWave delivers. They stock everything from low-molecular-weight fucoidan (great for absorption in supplements) to high-potency extracts for skincare. Plus, their minimum order quantities (MOQs) are flexible—starting at just 1kg for powders, which is a win for small businesses.

Standout Products:
Their star offering is a pharmaceutical-grade fucoidan extract with 95% purity, which is popular among local drug manufacturers. They also produce a "skin-specific" fucoidan powder, designed to boost collagen production—perfect for cosmetic brands.

Their extraction process uses only purified water and low heat, avoiding harsh chemicals.
Who They Serve:
Most of their clients are small to medium-sized health food stores and wellness brands, but they also cater to individual buyers through their online store. Their bestseller? A 200g fucoidan powder pouch, ideal for adding to smoothies or homemade supplements.
