1. Product Introduction

Trans-Resveratrol (CAS 501-36-0) is a high-activity natural polyphenolic antioxidant widely present in grape skins, peanuts, blueberries, cocoa and other natural plants. Our trans-resveratrol is mainly extracted from Polygonum Cuspidatum root, supplemented by mature biosynthesis technology, available in multiple specifications ranging from 10% to 99% HPLC purity.

All products are free of harmful carcinogens such as PAHs, with sufficient in-stock supply of 2000kg for fast shipment. We support third-party authoritative testing and free sample provision. Widely applicable in functional food, dietary supplements and cosmetic raw materials, it is included in the International Nomenclature of Cosmetic Ingredients (INCI) standard catalog, with safe and reliable quality.

2. Core Benefits & Physiological Functions

2.1 Powerful Antioxidant & Anti-Aging

As a high-activity natural polyphenol, trans-resveratrol can effectively neutralize excess free radicals in the human body, reduce oxidative damage to cells and DNA, delay skin and body aging, and inhibit the occurrence of various chronic oxidative stress-related diseases.

2.2 Cardiovascular Protection

It can effectively dilate blood vessels, accelerate systemic blood circulation, assist in regulating blood pressure, improve vascular elasticity, and prevent vascular sclerosis and cardiovascular and cerebrovascular lesions, providing comprehensive protection for heart and blood vessel health.

2.3 Anti-Tumor Activity

Trans-resveratrol can inhibit the proliferation, growth and metastasis of various tumor cells, and induce the apoptosis of abnormal tumor cells. It has broad auxiliary prevention and intervention effects on multiple cancers, and is a popular raw material for anti-tumor health research.

2.4 Improve Cognitive & Neurological Health

It can protect nerve cells from oxidative damage, optimize brain metabolism, improve human learning and memory ability, and effectively prevent age-related neurodegenerative diseases such as Alzheimer's disease.

2.5 Anti-Inflammatory & Immune Regulation

With excellent natural anti-inflammatory activity, it can inhibit excessive inflammatory reactions in the body, relieve tissue inflammation and pain symptoms, reduce the risk of chronic inflammatory diseases, and balance human immune function.

3. Main Application Fields
