Red wine extract is an alcohol-free solid powder, rich in polyphenolic antioxidants, including oligomeric proanthocyanidins (OPC), anthocyanins, quercetin, myricetin, resveratrol, etc. Red wine extract is one of the OPC 3 ingredients in FrenchGlory® isotonic OPC products. Natural “French Paradox” is about French red wine extract polyphenols, which contribute to the French heart health & longevity and fight nutritional deficiency due to imbalanced diet.

Characteristics of Red Wine Extract

Red wine extract is relatively economical, and less technologically demanding than grape seed extract and pine bark extract. The compositions in red wine extract distinguish red wine extract from grape seed extract and pine bark extract. Red wine extract contains less concentrated OPC and more diverse antioxidant natural products. There are many red wine extracts in the market that only contain 30-50% total polyphenols and 5-15% OPCs. Many red wine extract manufacturers do not give the information of OPC content at all in their papers of ingredient specifications. The higher grade red wine extracts contain 90-95% polyphenols, including OPC in 15-30%. The overall antioxidant activity of red wine extract is close to that of grape seed OPC extract or pine bark OPC extract.

Limitation of Wine

Traditionally, the nutritional benefits of wine as antioxidant recognized in many cultures are limited to people who enjoy alcohol. Many people, who do not like the alcoholic taste of this wonderful gift of red wine from nature, are left out from the nutritional benefits of the antioxidants in it. On the other hand, although occasional red wine consumption benefits the human body due to OPCs and other polyphenols such as anthocyanins, resveratrol, too much alcohol causes damages to the human body. Drinking red wine limits health benefits that human can get from OPCs, anthocyanins, resveratrol, and other polyphenol antioxidants.

ExGrape ® TOTAL Polyphenol Extract

ExGrape ® TOTAL PE, a red wine grape extract we use is made by GRAP'SUD, - a native French company specialized in the manufacture of grape by-products including red wine extract polyphenols from red wine grapes since 1969.

ExGrape ® TOTAL is an OPC ingredient extracted from grape marc in a ratio of 500:1. As comparison, Vitaflavan ® OPC is extracted from grape seeds in a ratio of 150:1, and Oligopin ® OPC from pine bark in a ratio of 1000:1.

Red wine polyphenols are excellent nutritional supplement, not a drug

The heart health benefits of red wine extract were well recognized by epidemiological studies of red wine consumption in France, leading to the French Paradox theory in the early 1990s. A long-term ongoing intake of alcohol-free red wine extract may prevent nutrition-deficient health problems, leading to longevity. Antioxidant deficiency is among the major nutritional deficiencies caused by imbalanced diet. Extensive scientific investigations have been conducted on both the whole red wine extract and individual polyphenol components. The antioxidant activity of polyphenols in the red wine extract occupies the center stage of the interests. Red wine extract polyphenols as antioxidants in vitro and in vivo studies indicate the nitritional benefits for oxidative stress related diseases - cardiovascular diseases, cancer, or chronic inflammatory processes. It should be emphasized that red wine extract is under investigations in treating a variety of diseases. But its current commercial use is limited to as dietary supplement, not intended to treat, prevent, cure, or diagnose any diseases.
