Product Introduction
Organic Resveratrol 98% powder is a plant‑sourced polyphenol extracted from organically cultivated Polygonum cuspidatum (Japanese knotweed) via standardized purification processes, with no synthetic additives, fillers, or carriers.
Resveratrol exerts biological activities through well‑defined molecular pathways:
- Antioxidant action: Acts as a direct free‑radical scavenger and activates the Nrf2‑Keap1 signaling cascade, upregulating expression of phase II antioxidant enzymes (e.g., SOD‑1, catalase, HO‑1) to reduce intracellular ROS and oxidative stress.
- Anti‑inflammatory effect: Modulates arachidonic acid metabolism, inhibits NF‑κB translocation, and reduces pro‑inflammatory cytokine production (e.g., TNF‑α, IL‑6).
- Metabolic regulation: Activates AMPK/SIRT1/PGC‑1α signaling to enhance mitochondrial biogenesis, improve insulin sensitivity, and support lipid homeostasis.
- Cardiovascular support: Promotes endothelial function by enhancing eNOS activity and nitric oxide bioavailability, helping maintain normal vascular tone and circulation.
This ingredient is manufactured for use in dietary supplements, nutraceutical formulations, and cosmetic actives where consistent purity and mechanistic activity are required.

- Rare effects: Transient headache, dizziness, or asymptomatic mild elevation of liver enzymes at very high doses.
- Drug interactions: May potentiate effects of anticoagulants, antiplatelet agents, and certain CYP3A4/CYP2C9 substrates; increased bleeding risk is possible.
- Special populations: Not recommended during pregnancy/lactation without professional guidance. Individuals with hormone‑sensitive conditions should consult a healthcare provider prior to use.
- Topical safety: CIR expert panel concludes resveratrol is safe for cosmetic use at concentrations up to 1%.
- Certifications: ISO, Kosher, Halal, Non‑GMO, Allergen‑Free, Non‑Irradiated, Anti‑Doping compliant.
