What Is Euglena Gracilis Extract?
Euglena Gracilis Extract (INCI: Euglena Gracilis Extract / Euglena Gracilis Polysaccharide) is a microalgae-derived active obtained from the single-celled green alga Euglena gracilis. Its signature component is paramylon, a rare crystalline β-1,3-glucan storage polysaccharide produced in exceptionally high content by this microalga. The extract is supplied as a white to off-white fine micro-powder and holds FDA GRAS status for food use, making it one of the few algae actives that crosses cleanly between nutrition and personal care.
Demand is accelerating on both sides of the industry: search interest in Euglena-based ingredients has grown sharply year over year, and Japanese ingredient leader Euglena Co. confirmed a new cosmetic function in February 2026 — paramylon helps suppress the adhesion of pollen and PM2.5 particles to the skin surface.
How It Works
In supplements, paramylon’s triple-helical β-glucan structure engages immune receptors such as dectin-1 on macrophages and dendritic cells, supporting balanced immune response. A 12-week randomized, double-blind trial in Japanese adults using 2.6 g/day of paramylon-rich E. gracilis reported significant reductions in visceral fat area and improved HbA1c, alongside increased adiponectin.
Topically, the insoluble micro-particles form a breathable protective film that conditions the skin, supports moisture factors via skin-immune pathways, and shields against particulate pollution — a formulation story that matches the fast-growing anti-pollution skincare segment.
Key Application Areas
- Immune-support and gut-health supplements (capsules, powders, tablets)
- Weight-management and metabolic health formulas targeting visceral fat
- Anti-pollution skincare — barrier creams and daily serums
- Soothing formulations for sensitive, redness-prone skin
- Functional foods and beverages with clean-label algae positioning
