What is Grape Skin Powder?Grape skin comes the ubiquitous berry found in several regions of the world. The skins of grapes contain one of the earliest domesticated organisms, yeast, which is the catalyst to one of the world’s most famous beverages: wine. The cultivation of grapes began nearly 8,000 years ago. Grapes grow in clusters of up to 300 and vary in color, from black to pink.Though everyone knows the benefits and applications of grapes, the skin itself is a great source of nutrition. Grape skin is known to contain resveratrol, a polyphenolic compound that is believed to give red wine its benefits.Grape skin powder also makes a good source of vitamin E, linoleic acid, and a plethora of antioxidants. This makes grape skin perfect for several applications. A few great ways to use grape skin is to add it to a multivitamin capsule formula or as an extra ingredient in functional foods and beverages.Organic Grape Skin Powder is made from organic red grapes, and provides in powder format a rich source of the polyphenols found naturally in grape skins that give rise to the health benefits noted in the French Paradox.

Grape Skin Powder Benefits:The benefits of red wine have been widely documented, and much of their health protecting properties have been traced back to the rich content of polyphenols contained in the skin of the red grapes used to make red wines.
Polyphenols and the French Paradox
The polyphenols found in naturally high concentrations in red grape skins are believe to give rise to the French Paradox. When studying the diets of western counties a disparity was found between the high levels of saturated fats generally consumed in the French diet and the incidence of heart disease. Whilst there is usually a strong correlation between the two in most countries, this was not the case in France. Further studies identified that whilst the French do have a fat-rich diet, they also tend to consume red wine with their meals. Red wine is shown to have protective effects against heart disease that can largely be attributed to the polyphenols, and particularly resveratrol, contained in the skins of red grapes.
Bioflavonoids and their Antioxidant Effect
The red colouration of grape skins, that gives rise to the deep red colour of the Grape Skin Powder, is due to the pigment anthocyanin. Anthocyanin is a bioflavonoid that is highly antioxidising, and is the main contributing factor to the remarkably high ORAC value found in the organic grape skin powder. At a level of over 5,000 ORAC units in a 5g serve of powder, this provides the full daily antioxidant requirement necessary for maintaining a healthy diet.
Benefits of Fermentation
The process of fermenting foods is an ancient art, and increasingly it is being recognised today for the role it plays in boosting the nutritional benefits of foods. Apart from breaking down more complex sugars, proteins and fats into more easily digestible, and therefore more bioavailable, formats, fermentation can also enhance the nutritional content of a food. This is especially true in the case of fermenting red grapes, where the levels of cardioprotective resveratrol are increased through the fermentation process necessary for wine making. Resveratrol is produced naturally by grape skins to protect the fruit from fungal infections. Since the grapes are exposed to yeast in the fermentation process in the making of red wine, it causes the red grape skins to synthesise more resveratrol, thereby increasing the overall levels found in the grape skins.
Nutrient Rich Food Source
Apart from being an excellent source of polyphenols, and their related health benefits,Red Grape Skin Powder is also a nutrient dense food providing a valuable source of fibers, vitamins and minerals. The table here provides a comparison of the nutrient concentration as compared to other foods.
