Key Bioactive Component of Polygonum Cuspidatum Extract Powder: Resveratrol

The key active chemical in the product is resveratrol, which provides a wide range of health-supporting effects. This natural polyphenol is a potent antioxidant, due to its ability to scavenge free radicals and protect cells against oxidative damage.

Resveratrol is known to activate proteins called sirtuins, which are involved in ageing and metabolism. It helps the heart by supporting healthy blood pressure levels and improving cholesterol levels.

It may also help to decrease inflammation, increase insulin sensitivity, and benefit brain function. Its resistance to external stresses makes it a beneficial ingredient in nutritional supplements and topical skincare treatments.

Our technical staff can help you optimise resveratrol for your unique use and improve its bioavailability with innovative delivery technologies.
