Welcome to Extract Warehouse, a premier manufacturer and global supplier of high-quality botanical extracts and nutraceutical raw materials. Among our flagship ingredients is our premium Trans-Resveratrol Powder, a highly sought-after natural polyphenol renowned for its potent antioxidant properties. Sourced from the roots of Polygonum cuspidatum, our resveratrol extract is meticulously processed to deliver exceptional purity, stability, and efficacy for the dietary supplement, cosmetic, and functional food industries.
Product Overview: High-Purity Trans-Resveratrol
Trans-resveratrol is the biologically active isomer of resveratrol, a natural phytoalexin produced by several plants in response to environmental stress or pathogenic attack. Unlike standard resveratrol, which often contains a mixture of less stable cis- and trans-isomers, our extract is specifically standardized to ensure a high concentration of the trans-isomer. This distinction is critical for formulators, as trans-resveratrol offers superior oxidative stability, enhanced bioavailability, and robust scientific backing for cellular health and anti-aging applications.
Extract Warehouse provides high-purity Trans-Resveratrol Powder in multiple assay levels, standardized via High-Performance Liquid Chromatography (HPLC). Compared to conventional ingredients, our high-purity trans-resveratrol ensures consistent performance, making it the preferred choice for premium dietary supplement brands, contract manufacturers, and cosmetic formulators worldwide.
