(Black Ginger Extract (Kaempferia parviflora)) is a botanical extract derived from Kaempferia parviflora (Thai black ginger) rhizome, standardized to 5,7,4'-Trimethoxyflavone. With CAS registry number 21392-57-4, this ingredient belongs to the Metabolism & Lipid Regulators category of weight management actives. PMFs activate SIRT1+AMPK (dual pathway, similar to resveratrol but better bioavailability). SIRT1→PGC-1α→mitochondrial biogenesis→fat oxidation. AMPK→metabolic shift to catabolism. Specifically reduces visceral fat 20-30% in animal models — selective visceral fat effect. As a B2B manufacturer, Shaanxi Baisifu Biological Engineering Co., Ltd. supplies Black Ginger Extract (Kaempferia parviflora) in bulk quantities with full Certificate of Analysis (COA), ensuring consistent 5,7,4'-Trimethoxyflavone content and regulatory compliance for dietary supplement, functional food, and nutraceutical applications.

Q1: What is Black Ginger vs. regular ginger?
Different species (Kaempferia parviflora vs. Zingiber officinale). Contains polymethoxyflavones (not gingerols). Mechanism: metabolic regulation (SIRT1/AMPK) vs. thermogenesis (TRPV1). Thai traditional medicine origin.
Q2: Effective for visceral fat?
Yes — 20-30% visceral fat reduction in preclinical studies. SIRT1/AMPK specifically targets adipose tissue metabolism. Suitable for "stubborn belly fat" positioning.
For complementary weight management formulations, consider combining Black Ginger Extract (Kaempferia parviflora) with: Resveratrol, Capsaicin, 6-Paradol, Forskolin. Multi-ingredient stacks targeting different mechanisms (lipase inhibition, AMPK activation, thermogenesis, appetite suppression) produce synergistic effects superior to single-ingredient products.
