L-Fucose is a bioactive deoxy sugar used in pharmaceuticals, cosmetics, biomedical research, and functional foods. It supports immune signaling, skin hydration, and gut-friendly formulations.
Erythritol is a naturally occurring sugar alcohol (polyol) produced through enzymatic fermentation of corn. It is also found in fruits like grapes and pears, as well as in fermented foods such as beer and soy sauce. Offering 60–80% of the sweetness of sucrose with just 0.2–0.4 kcal/g, Erythritol is non-cariogenic, non-glycemic, and heat-stable up to 120°C. This makes it ideal for use in low-calorie food products, diabetic-friendly.

L-Fucose is extracted and purified from natural sources like marine algae, plant gums, and bacterial polysaccharides. This deoxyhexose sugar (6-deoxy-L-galactose) is characterized by the absence of a hydroxyl group at the C-6 position, which gives it unique hydrophobic properties. The resulting high-purity crystalline powder (≥99%) is stable and suitable for use across food, pharma, and cosmetic sectors.
L-Fucose plays a key biological role in immune response, cell adhesion, and signaling. It supports hydration and anti-aging in skincare, gut health in supplements, and targeted drug delivery in medical applications. Its low glycemic impact makes it a beneficial ingredient for functional foods and cosmetics.

Unlike regular sugars, L-Fucose is a functional monosaccharide with structural roles in the body. It is not used for energy but supports glycoprotein formation and cellular processes. Its low sweetness and negligible caloric value make it ideal for specialized formulations rather than general sweetening.
Whether you're developing anti-aging skincare, advanced therapeutics, or gut-friendly supplements, L-Fucose delivers functional performance across industries. With its safety, versatility, and scientific relevance, L-Fucose is a smart ingredient for innovative, health-forward formulations.
