Proanthocyanidin (PA or PAC), also known as procyanidin, oligomericproanthocyanidin (OPC), leukocyanidin, leucoanthocyanin and condensed tannins, is a class of flavanols.


Polyphenols are a group of chemical substances found in plants, characterized by the presence of more than one phenol unit or building block per molecule. Polyphenols are generally divided into hydrolyzable tannins (gallic acid esters of glucose and other sugars) and phenylpropanoids, such as lignins, flavonoids, and condensed tannins.


Antioxidants are compounds that have the capacity to neutralize reactive oxygen species. Oxygen free radicals generated by oxidative and other biochemical pathways are the main cause for a number of degenerative diseases. Antioxidants act as radical scavengers, and convert the radicals to less reactive species. The imblanace due to the presence of excess free radicals and lower antioxidants causes oxidative stress and many chronic health problems such as cancer, atherosclerosis, myocardial infraction, senile cataracts, and rheumatoid arthritis.Research indicates that GSE Proanthocyanidins/Polyphenl has strong Antioxidants. Its antioxidative is 50times than Vitamin E, and 20times than Vitamin C.


Our ORAC Grape seed P.E is extracted via purified water, which can keep the activity of Proanthocyanidins and Polyphenols.
