1. What is Mulberry Leaf Extract?

Mulberry Leaf Extract is a natural plant extract derived from the leaves of Morus alba L., processed using advanced water-ethanol and supercritical CO₂ extraction technologies. The extract is standardized for 1.5–3% DNJ (1-Deoxynojirimycin), a bioactive compound associated with metabolic support in scientific studies. It contains flavonoids, polysaccharides, and phenolic compounds with consistent quality and purity for functional ingredient applications.

2. Primary Mechanisms & Functional Highlights

• DNJ Content (≥1.5%): Inhibits α-glucosidase activity, providing a scientifically supported metabolic mechanism.

• Flavonoids & Polyphenols: Contribute to antioxidant capacity, stability in formulations, and color preservation.

• Polysaccharides: Support solubility and functional integration in food and beverage applications.

⚠️ Note: This product is a nutritional ingredient, not a medication. It is intended for professional formulation and industrial use.

3. Health Applications & Usage Guidance

• Target Industries: Dietary supplements, nutraceuticals, functional beverages, cosmetic actives.

• Traditional Applications: Used historically in herbal teas and functional formulations.

• Recommended Dosage for Formulation: Typical 150–300 mg per serving (capsule/tablet) or 0.1–0.5% w/w in beverages and functional foods.
