10%-98% Polygonum cuspidatum extract Trans-Resveratrol Powder
What is Polygonum cuspidatum extract Trans-Resveratrol Powder?
Resveratrol, also known as tristilbene and tristilbene, is a stilbene polyphenol compound with a stilbene structure. Resveratrol appears as white, needle-shaped crystals and is poorly soluble in water.
Resveratrol is a self-protective factor produced by plants in response to stimuli. It was originally isolated from the roots of the North American plant Veratrum, hence its name.
Resveratrol has significant biological activity, including anti-tumor, cardiovascular protection, antioxidant, antibacterial, antiviral, hepatoprotective, anti-inflammatory, and immune-modulating effects. It can also be used as a dietary supplement for health and disease prevention. Resveratrol inhibits tyrosinase, monophenolase, and diphenolase, and has a whitening effect on human skin tissue.
Key Features
1. Powerful Antioxidant and Anti-Inflammatory Effects
This is the most fundamental and core benefit of resveratrol, from which many other benefits stem.It effectively neutralizes free radicals in the body, reducing oxidative stress damage to cells, DNA, and proteins. Oxidative damage is a major contributor to aging and many chronic diseases.It inhibits inflammatory pathways such as NF-κB, reducing the production of inflammatory factors. Chronic inflammation is a common root cause of many diseases, such as heart disease, arthritis, and even cancer.
2. Protects the Cardiovascular System
It may help lower "bad" cholesterol (LDL) levels and increase "good" cholesterol (HDL).
Prevents Arteriosclerosis: Through its antioxidant properties, it prevents LDL cholesterol from oxidizing, thereby reducing the formation of atherosclerotic plaques. It reduces blood viscosity, reducing the risk of thrombosis.By stimulating the production of nitric oxide (NO), it helps blood vessels relax and dilate, thereby helping to lower blood pressure.
3. Anti-Cancer Properties
Currently limited to laboratory research, resveratrol is still far from becoming a cancer treatment, but it shows promise. In test-tube and animal studies, resveratrol has been shown to inhibit the proliferation of various cancer cells (such as breast, prostate, stomach, and colon cancers). Apoptosis Induction: It can induce cancer cells to undergo programmed cell death (apoptosis). It may inhibit the formation of new blood vessels within tumors, thereby "starving" the tumor.
4. Neuroprotective Effects
Its antioxidant and anti-inflammatory properties help protect brain cells from damage.

Package & Storage
Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
