Product Description

Natural Polygonum cuspidatum extract 98% 10% Resveratrol

 

1. Introduction:
   Resveratrol is a natural polyphenolic compound found in various plants, particularly in the skin of red grapes, and Japanese knotweed. It gained significant attention for its potential health benefits, including antioxidant, anti-inflammatory, and cardioprotective properties. Research suggests that resveratrol may mimic the effects of calorie restriction, activating longevity-associated pathways like SIRT1. It has also been studied for its potential role in cancer prevention, neuroprotection, and diabetes management. While promising, many findings are based on preclinical studies, and human trials remain limited. Resveratrol is available as a dietary supplement, but its bioavailability is relatively low.
