Lotus Leaf Extract is a botanical extract derived from Folium Nelumbinis (Nelumbo nucifera), standardized to Nuciferine. With CAS registry number 481-31-8, this ingredient belongs to the Metabolism & Lipid Regulators category of weight management actives. Nuciferine is a natural pancreatic lipase inhibitor — directly blocks the enzyme digesting dietary fats. Same mechanism as orlistat (prescription drug) but natural origin with fewer GI side effects. Also downregulates FAS gene and elevates BMR. One of few botanical weight-loss ingredients with formal Chinese regulatory approval . As a B2B manufacturer, Shaanxi Baisifu Biological Engineering Co., Ltd. supplies Lotus Leaf Extract in bulk quantities with full Certificate of Analysis (COA), ensuring consistent Nuciferine content and regulatory compliance for dietary supplement, functional food, and nutraceutical applications.

Q2: Standard formulation?
+lotus leaf + green tea polyphenols — lipase inhibition + fat oxidation. Basis for multiple -certified products.
Q3: Can be sold outside China?
Yes. Nuciferine not restricted in US/EU. Position as "natural lipase inhibitor" or "metabolic enhancement extract" for international B2B.
For complementary weight management formulations, consider combining Lotus Leaf Extract with: Green Tea Extract, L-Carnitine, Garcinia Cambogia Extract, Chitosan. Multi-ingredient stacks targeting different mechanisms (lipase inhibition, AMPK activation, thermogenesis, appetite suppression) produce synergistic effects superior to single-ingredient products.
