                          Feature

                          Natural resveratrol is mainly found in the root of Polygonum cuspidatum. The resveratrol content in the fresh root of Polygonum cuspidatum is higher than that in the fresh stem. However, high-content resveratrol can now be obtained through chemical synthesis and biological fermentation.
                          Resveratrol is a polyphenolic substance and a natural plant antibiotic. There are two geometric isomers: Cis and trans resveratrol powder. Trans resveratrol is more stable and has a higher active ingredient.
                          It appears as a white crystalline powder and is odorless. It is difficult to dissolve in water, but easily soluble in organic solvents such as ethanol and acetone.

                          What does resveratrol powder do?

                          As a natural polyphenol, resveratrol also plays an excellent functional role in promoting human nutritional health.
                          Resveratrol is mainly used in dietary supplements. In addition, it also includes newly launched foods and beverages, especially functional beverages.
                          It has antioxidant, anti-inflammatory and cardiovascular protection properties.

                          1. Resveratrol is an effective antioxidant. Secondly, it inhibits the activity of tyrosinase to reduce the synthesis of melanin and achieve a whitening effect.
                          2. Resveratrol can reduce inflammation and promote the expression of anti-inflammatory cytokines.
                          3. Clinical studies have shown that resveratrol has potential therapeutic effects on cardiovascular and neurological diseases.
