- Product Description
Premium Polygonum Cuspidatum Extract Resveratrol - 98% Purity Guaranteed
Are you looking for safe, legal, and Polygonum Cuspidatum Extract Resveratrol, specifically resveratrol? Its main active ingredient is trans-resveratrol, a stilbene polyphenol with the molecular formula C14H12O3. As a unique longevity gene activator, trans-resveratrol mimics the cell repair effects induced by calorie restriction. The Polygonum cuspidatum plant synthesizes this phytoalexin to protect itself from UV rays, bacteria, and other external factors.
Hongda Phytochemistry is one of the leading producers of resveratrol. We utilize "low-temperature nitrogen atomization crystallization" and "micro-encapsulation oxygen-barrier" technologies to provide ultrafine powder with a D90 of < 10μm. This micro-powder specification significantly increases the specific surface area of the raw material in the digestive tract. Combined with our emulsification and solubilization technology, it achieves a uniform suspension in cold water systems through a "pseudo-dissolution" process, overcoming the drawbacks of a gritty texture and low absorption rate in finished products. With 20 years of experience and advanced production facilities, we have become a trusted supplier of high-quality Plant Extracts. Our Polygonum Cuspidatum Extract Powder meets global quality standards and regulations and have a wide range of applications.

Why Our Resveratrol Stands Out
Our product includes more than 98% HPLC-verified resveratrol, originates from farms that are certified organic, and is ideal for health. Whether you make pills, tablets, or liquid vitamins, we provide your firm the stability and approvals it needs.
