Xi an Pincredit Bio-tech Co., Ltd sell "Pterostilbene Powder"

Pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene) is a white to off-white polyphenol powder that plays a defensive phytoalexin role in plants. Compared with its chemical relative resveratrol, it offers better bioavailability and lipophilicity, making it easier for the body to absorb. Research points to strong antioxidant activity — scavenging free radicals and boosting cellular energy — along with anti-inflammatory effects that may lower skin cancer risk and help reduce blood pressure. It is already used in numerous skincare products and anti-aging supplements. Note that pterostilbene is hazardous on eye contact and is considered an environmental toxin, particularly to aquatic life. Sold wholesale directly from the manufacturer.
