Introduction

For centuries, plants rich in resveratrol—such as grapevines and Polygonum cuspidatum—have been valued in traditional medicine for their health-promoting properties. Modern scientific research has highlighted Trans-Resveratrol (the biologically active isomer) as a potent polyphenol with remarkable anti-aging and wellness benefits. As a leading manufacturer of high-purity plant extracts, Hangzhou Greensky Biological Tech.Co.,Ltd delivers Trans-Resveratrol Powder standardized to 98% purity, bringing research-backed, natural efficacy to global partners across nutraceutical, food, and cosmetic industries.

Part 1: What is Trans-Resveratrol Powder 98%?

Source Plant

Our Trans-Resveratrol is primarily sourced from Polygonum cuspidatum (Japanese knotweed), a perennial herb belonging to the Polygonaceae family. Native to East Asia (China, Japan, Korea), this plant is renowned for its high resveratrol content—far exceeding that of grapes or berries. We cultivate Polygonum cuspidatum in pollution-free regions of China (Zhejiang, Anhui, and Shaanxi provinces) under strict organic farming standards, ensuring premium raw material quality.

Extracted From

The powder is derived from the dried roots and rhizomes of Polygonum cuspidatum, where Trans-Resveratrol is most concentrated (up to 1.5% in raw material). The plant material is carefully harvested at peak maturity (autumn season) to maximize resveratrol yield.

Active Components

The core active ingredient is Trans-Resveratrol (98% HPLC-verified)—the trans-isomer is the only biologically active form, with superior bioavailability and stability compared to the cis-isomer. Trace complementary compounds include:

Polydatin (resveratrol-3-O-β-D-glucoside), a natural precursor that converts to resveratrol in the body.

Flavonoids (e.g., Quercetin, rutin) that enhance antioxidant synergy.

Standardized Specification

We offer Trans-Resveratrol Powder with industry-leading, consistent specifications:

Core standard: 98% Trans-Resveratrol (HPLC-determined)—the highest purity for maximum efficacy.

Optional specifications: 95%, 99% purity; micronized particle size (100-200 mesh) for enhanced solubility.

Physical form: Off-white to pale yellow fine powder, soluble in ethanol, DMSO, and partially soluble in water (solubility improved with microencapsulation).

Moisture content: ≤5% (ensures long-term stability and prevents clumping).

Heavy metal limit: Pb, Cd, Hg, As < 0.5ppm (exceeds global safety standards).

Testing Report

Every batch of our Trans-Resveratrol Powder 98% comes with a comprehensive Certificate of Analysis (COA), including:

Trans-Resveratrol purity verification (HPLC method, ≥98%); cis-resveratrol content < 1% (ensures bioactivity).

Heavy metal screening (compliant with FDA, EU REACH, and Chinese national standards).

Pesticide residue analysis (meets EU MRLs for organic crops—no synthetic pesticides detected).

Microbial testing (total aerobic bacteria < 500 CFU/g; yeast & mold < 100 CFU/g; Salmonella/coliforms absent).

Solvent residue detection (ethanol < 50ppm; no toxic solvents used in extraction).

Third-party lab verification (e.g., SGS, Intertek) is available upon request for full transparency.

Part 2: Key Health Benefits and Mechanisms of Action

Trans-Resveratrol Powder 98%’s benefits are supported by decades of scientific research, with its mechanism of action centered on activating longevity pathways and neutralizing cellular damage:

Anti-Aging & Cellular Longevity: Trans-Resveratrol activates the SIRT1 gene (the "longevity gene") and increases NAD+ levels, slowing cellular senescence and extending cell lifespan. A study published in Cell Metabolism (2020) demonstrated that 98% pure resveratrol improved mitochondrial function and reduced age-related biomarkers in human cells (PubMed ID: 32845395).

Cardiovascular Health Protection: It supports vascular health by enhancing nitric oxide production (relaxing blood vessels), inhibiting LDL ("bad" cholesterol) oxidation, and reducing platelet aggregation. A clinical trial in Circulation Research (2019) found that daily supplementation reduced systolic blood pressure by 6 mmHg and improved endothelial function in adults with mild hypertension.

Potent Antioxidant Activity: Trans-Resveratrol scavenges free radicals (e.g., superoxide anion, hydroxyl radical) and upregulates endogenous antioxidant enzymes (SOD, glutathione peroxidase), reducing oxidative stress linked to chronic diseases. Food Chemistry (2021) reported its ORAC value at 15,000 μmol TE/g—5x higher than vitamin C.

Anti-Inflammatory Effects: It inhibits pro-inflammatory cytokines (TNF-α, IL-6) and blocks NF-κB signaling pathways, easing chronic inflammation associated with arthritis, metabolic syndrome, and neurodegenerative diseases. Research in Journal of Ethnopharmacology (2022) confirmed its efficacy in reducing joint inflammation in animal models.

Supports Metabolic & Cognitive Health: Trans-Resveratrol improves insulin sensitivity by activating AMPK (a key metabolic regulator), helping manage blood glucose levels. It also crosses the blood-brain barrier to protect neurons from oxidative damage—studies in Neuroscience (2020) linked it to improved memory and reduced risk of age-related cognitive decline.

Part 3: Wide-Ranging Application Industries

Our premium Trans-Resveratrol Powder 98% is a versatile ingredient trusted by industries worldwide for its high purity and bioactivity:

Dietary Supplements and Nutraceuticals: Formulated into capsules, tablets, and powdered supplements targeting anti-aging, cardiovascular health, metabolic support, and cognitive wellness. Popular among middle-aged adults, athletes, and wellness enthusiasts seeking natural longevity solutions.

Functional Foods and Beverages: Incorporated into Red Wine Extracts, energy drinks, protein shakes, and fortified snacks (e.g., dark chocolate bars, gummies) to add antioxidant and anti-aging benefits. Its neutral flavor makes it easy to integrate without altering taste profiles.

Cosmetics and Personal Care: Used in anti-aging serums, moisturizers, eye creams, and facial masks—activates skin cell longevity, reduces fine lines, and protects against UV-induced damage. Also added to hair care products to strengthen hair follicles and reduce oxidative stress.

Animal Nutrition: As a natural feed additive for companion animals (dogs, cats) and livestock (horses, poultry) to improve immune function, reduce inflammation, and support healthy aging—enhancing overall vitality and performance.

Part 4: How to Choose a High-Quality Trans-Resveratrol Powder

Selecting a reliable supplier is critical to ensuring product safety, efficacy, and value. Key factors to consider:

Verified Purity & Isomer Ratio: Ensure the powder is HPLC-verified to 98% Trans-Resveratrol with <1% cis-isomer. Low-purity products (below 95%) often contain fillers or inactive cis-isomer, reducing bioactivity.

Extraction Technology: Choose suppliers that use gentle, solvent-free methods (e.g., supercritical CO2 extraction or ethanol-water extraction) to preserve Trans-Resveratrol’s structure. Hangzhou Greensky’s advanced purification process removes impurities while retaining 99% of bioactive compounds.

Raw Material Authenticity: Prioritize powder sourced from Polygonum cuspidatum (not grape pomace, which has lower resveratrol content). Ask for proof of raw material testing and cultivation standards.

Stability & Solubility: High-quality Trans-Resveratrol should be stable under proper storage (cool, dry conditions) and offer customizable solubility (e.g., microencapsulated water-soluble variants). Avoid products that clump or degrade quickly.

Certifications: Look for GMP, ISO 9001, organic (USDA/NOP, EU Organic), and Non-GMO Project Verified certifications—markers of compliance with global quality and safety standards.
