产品说明

1. Product Introduction

Our Grape Seed Extract is a high-quality plant extract derived from high-quality grape seeds. It is rich in a variety of beneficial active ingredients. With powerful antioxidant capacity and high health value, these ingredients are widely recognized and applied in various industries.

2. Active Ingredients

Proanthocyanidins

The main active ingredients in Grape Seed Extract are proanthocyanidins, including oligomeric and polymeric proanthocyanidins. These compounds are well known for their strong antioxidant, free radical scavenging and anti-inflammatory properties and are recognized as high-quality natural antioxidant substances.

In particular, proanthocyanidins have been widely studied. Research shows that they can effectively neutralize excess free radicals in the human body and reduce oxidative damage. Free radicals are closely associated with aging, skin dullness, vascular aging and various chronic sub-health problems.

Polyphenols and Flavonoids

Grape Seed Extract also contains abundant polyphenols, catechins and natural flavonoids, which endow the product with unique physiological activity. These ingredients provide mild antibacterial, anti-inflammatory and vascular-protective effects, further enhancing the comprehensive health benefits of Grape Seed Extract.

3. Appearance & Properties

Color

Our Grape Seed Extract generally presents a uniform reddish-brown to brown fine powder. The color is formed by the high content of natural proanthocyanidins and polyphenols, and higher ingredient content results in purer and richer color.

Form

It is available in multiple forms such as fine powder and liquid extract. The powder features fine texture and good fluidity for easy handling, and can be processed into dietary supplements and other finished products. The liquid extract has higher concentration and stronger activity, suitable for applications requiring high concentration and high solubility.

Solubility

Conventional powder has ordinary water solubility and disperses better in oil-based systems. With advanced extraction and formulation technology, water-soluble Grape Seed Extract is fully developed to meet the production requirements of food, beverages, skincare products and other fields.

4. Health Benefits

Antioxidant Protection

As mentioned above, proanthocyanidins in Grape Seed Extract deliver strong antioxidant effects. They protect cells from oxidative damage caused by free radicals, eliminate aging factors, effectively delay body and skin aging, and reduce the risk of chronic sub-health problems.

Anti-Inflammatory Properties

Grape Seed Extract has been proven to have significant anti-inflammatory effects. It helps reduce chronic inflammation in the body, relieve skin redness and sensitivity, and improve mild physical and skin inflammatory discomforts.

Vascular Health

Studies have shown that active ingredients of grape seeds positively support vascular health. They enhance vascular elasticity, improve body microcirculation, protect cardiovascular status, and maintain normal metabolism and circulation functions of the body.

Skin Care & Anti-Aging

Proanthocyanidins and polyphenols in Grape Seed Extract inhibit melanin precipitation, improve skin dullness, roughness and fine lines, and maintain hydrated, bright, firm and glossy skin, serving as a natural anti-aging skincare raw material.
