Double Wood’s Resveratrol provides 500 mg of resveratrol from Japanese knotweed (Polygonum cuspidatum) root per serving—a naturally rich plant source of resveratrol. Standardized to 50% trans-resveratrol, each two-capsule serving delivers 250 mg of trans-resveratrol, the bioactive form commonly used in resveratrol research.Resveratrol is a naturally occurring polyphenol with antioxidant properties. It is commonly taken to support antioxidant defenses, cardiovascular health, cellular function, and healthy aging.Resveratrol has also been studied for its influence on sirtuin signaling, particularly SIRT1. SIRT1 is an NAD+-dependent protein involved in cellular energy metabolism, stress responses, and mitochondrial function—pathways that help explain resveratrol’s role in healthy-aging research.Research has also examined trans-resveratrol’s effects on cerebral blood flow, although more study is needed to understand its potential cognitive benefits.Soy-Free, Gluten-Free, Non-GMO, Vegan
