Introduction to Grape Seed Extract
Grape Seed Extract (CAS 4852-22-6), derived from the seeds of Vitis vinifera L., is a premium botanical extract rich in oligomeric proanthocyanidins (OPCs), catechins, epicatechin, gallic acid, and epicatechin gallate. Recognized as one of nature’s most potent plant-derived antioxidants, it demonstrates antioxidant capacity 30–50 times greater than vitamins C and E.
Sourced from premium grape-growing regions in China, including Hebei, Henan, and Shaanxi, our grape seed extract is produced under strict quality control protocols. As a leading manufacturer and supplier of high-purity plant extracts, Botanical Essence ensures full traceability from vineyard to finished powder, delivering consistent potency, stability, and batch-to-batch uniformity for global nutraceutical, functional food, and cosmetic manufacturers.

Comprehensive Health Benefits and Functional Properties
Powerful Antioxidant & Immune Support
Grape Seed Extract exhibits exceptional free radical scavenging activity. By neutralizing reactive oxygen species (ROS), it helps reduce oxidative stress, supports cellular integrity, and enhances the body’s natural antioxidant enzyme systems, including SOD, catalase, and glutathione peroxidase. Clinical and preclinical research indicates it works synergistically with vitamin E, regenerating it and amplifying its protective effects. These properties make it a valuable ingredient for immune support formulations, cardiovascular health supplements, and daily antioxidant defense products.
Skin Health and Anti-Aging Applications
Rich in bioavailable anthocyanins and proanthocyanidins, Grape Seed Extract protects skin collagen and elastin from oxidative degradation. It improves microcirculation, strengthens capillary walls, and helps maintain skin elasticity and firmness. Widely used in premium nutraceuticals and cosmeceutical formulations, it supports healthy skin from within and contributes to reduced appearance of wrinkles, age spots, and photoaging.
Digestive and Gastric Support
The extract demonstrates protective effects on gastric mucosa, helping to relieve symptoms associated with gastritis, gastric ulcers, and duodenal ulcers. Its high polyphenol content supports a healthy inflammatory response in the gastrointestinal tract, making it suitable for gut-health focused dietary supplements.
Cardiovascular and Metabolic Health
Grape Seed Extract contains significant levels of linoleic acid and polyphenols that help regulate blood lipids, inhibit LDL oxidation, improve vascular elasticity, and support healthy blood pressure levels. These mechanisms contribute to reduced risk factors for atherosclerosis, thrombosis, and other cardiovascular concerns. It has also shown potential in improving insulin sensitivity, making it attractive for metabolic health formulations.
Cognitive and Brain Health Support
The combination of potent antioxidant and anti-inflammatory flavonoids in grape seed extract is studied for its ability to support brain health during aging. Gallic acid and proanthocyanidins may help inhibit beta-amyloid aggregation and reduce oxidative damage in neural tissue. Human studies have shown improvements in memory, attention, and cognitive performance with consistent supplementation.
Kidney Function Support
Kidneys are highly vulnerable to oxidative stress. Research indicates that Grape Seed Extract may help protect renal tissue by reducing oxidative damage and inflammatory markers, supporting healthier filtration function.
Additional Functional Benefits
- Supports healthy wound healing through stimulation of growth factors and collagen synthesis
- Demonstrates promising antimicrobial and antifungal activity against common foodborne pathogens and Candida species
- May help improve bone density and collagen levels, supporting skeletal health
- Provides natural defense against UV and blue-light radiation damage
Primary Applications
Dietary Supplements
Ideal for capsules, tablets, softgels, and powdered drink mixes targeting antioxidant support, cardiovascular health, skin beauty-from-within, and immune modulation.
Functional Foods & Beverages
