Grape Seed Extract is a type of natural plant substance that has rich flavonoids:Proanthocyanidins or procyanidins. In grape seed extract there are basically two proanthocyanidin monomers called catechin and epicatechin. Each of them binds at either the alpha or beta position on their molecular structures to form oligomers or polymers. According to Jacques Masquelier, grape seed extract is the best source of OPCs which has a content of 92-95% OPCs. Functions: A growing body of scientific evidence suggests that grape seed extract, especially OPCs, possesses a broad spectrum of biological, pharmacological and chemo-protective properties against free radicals and oxidative stress. Grape seed extract, best known for its anti-oxidant, has been shown to be 20 times greater than Vitamin C & 50 times stronger than Vitamin E. 1. Scavenges free radical,eliminate speckles 2. Enhances cardiovascular health. 3. Inhibits growth and formation of certain types of cancer. 4. Improves visual performance in humans. 5. Reduces symptoms of premenstrual syndrome. 6. Rreduces symptoms in gastric ulcers. 7. Protects cells against drug, chemical and environmental pollutants toxicity. 8. Reduce aging and loss of elasticity in skin. While the therapeutic potential of grape seed extract is quite broad, it is used primarily as nutritional/dietary supplement worldwide. Such as the United States, grape seed extract is given as dietary supplement for general health purposes and also used in functional foods such as cereals, beverages and even chewing gum. While in France grape seed extract is the active ingredient in a proprietary pharmaceutical product sold, which is used primarily for microcirculatory disorders. In asia such as Japan grape seed extract is widely used as an additive for various food applications. In a word, grape seed extract(OPCs) is the most important nature product of reducing aging and anticancer in the future. But now there are many kinds of specifications (OPCs) in the market. Only according to 10% above (monomers), 95% (procyanidins), 90% (polyphenols),it is truly grape seed extract(OPCs).To meet the needs of the market and wide clients, we specialize in producing and selling grape seed extract(OPCs).
