Used as a bioactive polysaccharide in nutraceutical and pharmaceutical research; exhibits anticoagulant, antithrombotic, anti-inflammatory, immunomodulatory, antioxidant, antiviral, antitumor, and anti-angiogenic activities; studied for potential use in treating cardiovascular diseases, cancer, kidney disorders (e.g., diabetic nephropathy), and as a prebiotic; used in cosmetic formulations for skin hydration and anti-aging; also used as a functional ingredient in dietary supplements derived from brown seaweeds (e.g., Fucus vesiculosus, Undaria pinnatifida, Laminaria japonica).
