Product Introduction:
Grape seed extract is a class of polyphenols extracted from grape seeds, mainly composed of proanthocyanidins, catechins, epicatechin, gallic acid, epicatechin gallate, and other polyphenols.

Grape seed extract is a pure natural substance, and is one of the most efficient antioxidants from plant sources found so far. Experiments have shown that its antioxidant effect is 30-50 times that of vitamin C and vitamin E.

Proanthocyanidins have extremely strong activity and can inhibit carcinogens in cigarettes. Their ability to capture free radicals in the aqueous phase is 2 to 7 times that of ordinary antioxidants, such as: α- The activity of tocopherol is more than twice as high.

Product Advantage:
Research has found that among many plant tissues, grape seeds and pine bark extracts have the highest content of proanthocyanidins, and the main methods for extracting proanthocyanidins from grape seeds include solvent extraction, microwave extraction, ultrasonic extraction, and supercritical CO2 extraction. The grape seed proanthocyanidin extract contains many impurities, which require further purification to improve the purity of proanthocyanidins. Common purification methods include solvent extraction, membrane filtration, and chromatography.

Product Function:
1. Beauty care
Grape seed extract is known as an edible cosmetic, which is rich in vitamins and antioxidant ingredients. After people use it, it can protect the collagen in the skin, improve skin elasticity, and prevent skin dullness. Regular consumption can prevent the formation of wrinkles, and also make people's skin smooth, tender, and elastic.
2. Improve immunity
After taking grape seed extract, people can also improve their anti allergic ability because grape seed extract contains a variety of active ingredients, which can inhibit the release of the allergenic factor histamine in the human body, enhance the tolerance of human tissue cells to allergens, stabilize skin blood vessels and tissues of various organs, and fundamentally prevent the occurrence of allergic symptoms.
3. Cardiovascular protection
Grape seed extract has an excellent protective effect on human blood vessels. Its antioxidant ingredients can delay vascular aging, increase vascular elasticity, and purify blood to reduce blood pressure and blood lipids. Usually people use health products made of grape seed extract to prevent arteriosclerosis, and also reduce the incidence rate of stroke and myocardial infarction. Grape seed extract can also enhance the anti aging and anti cancer abilities of the human body, and can also strengthen the brain and improve brain function.
4.nutritive value:
Grape seed extract has a wide range of effects. Grape seed extract is a new type of highly effective natural antioxidant substance extracted from grape seeds that cannot be synthesized in the human body. It contains a large amount of vitamin E, cellulose, and vitamin C, which is a strong antioxidant substance. After ingestion into the body, it can effectively whiten the skin, remove excess free radicals from the body, and have a strong role in delaying aging and enhancing immunity. Moreover, the fiber in it can increase the feeling of fullness, promote intestinal peristalsis, and improve the state of constipation. It is generally recommended to consume grape seeds in an appropriate amount after meals to prevent excessive coarse fiber from stimulating the gastric mucosa and causing abdominal distension.
