Fucoidan is a sulfated polysaccharide found naturally in the cell walls of brown seaweeds (Phaeophyceae), including species such as Undaria pinnatifida (Wakame), Fucus vesiculosus (Bladderwrack), and Laminaria japonica (Kombu). It is composed primarily of L-fucose (a deoxyhexose sugar) combined with sulfate ester groups, along with minor amounts of other monosaccharides (galactose, mannose, xylose, glucuronic acid).
Fucoidan has gained significant attention in nutraceutical, functional food, and cosmetic industries due to its multi-target biological activities, natural origin, and strong safety profile. The global fucoidan market is projected to grow at a CAGR of 10–12% through 2030, driven by immune health and gut health trends.

Q: What is the difference between fucoidan from different seaweed sources?
A: Undaria pinnatifida (Wakame) is the most clinically studied and widely accepted for nutraceuticals. Fucus vesiculosus (Bladderwrack) has higher sulfate content but also higher iodine. LyvBio uses Undaria pinnatifida for consistent quality and lower iodine.
Q: Is fucoidan vegan?
A: Yes. Fucoidan is derived from brown seaweed (marine algae), not from animals. All LyvBio fucoidan is 100% plant-based.
Q: Does fucoidan have blood-thinning effects?
A: Fucoidan has anti-coagulant activity in vitro (similar to heparin but much weaker). At typical supplement doses (250–1,000 mg), clinically significant blood thinning is unlikely. However, caution is advised for individuals on anticoagulant medications.
Q: What is the difference between high MW and low MW fucoidan?
A: High MW (>100k Da) has lower absorption but may be more effective for gut-local effects. Low MW (20–50k Da) has higher systemic bioavailability for immune modulation. Oligo-fucoidan (<10k Da) has the highest absorption for premium formulations.
Q: Is fucoidan stable in gummy formulations?
A: Yes, with proper formulation. Use low MW or oligo-fucoidan for better solubility. Taste masking (fruit flavors) is essential to cover the mild seaweed taste.
Q: What is the iodine content of your fucoidan?
A: LyvBio fucoidan is extracted and purified to remove most iodine. Typical iodine content is ≤50 ppm (significantly lower than whole seaweed, which can contain 500–5,000 ppm). This is safe for daily use.
Q: 最小注文数量（MOQ）はどれくらいですか？
A: サンプル注文：100g～500g。試作：1～5kg。量産：要相談（25kg以上は数量割引が適用されます）。納期：3～5日（サンプル）、10～15日（量産）。.
