In general, it is known as "the fountain of youth" because of its broad health benefits. More than 600 scientific researchers have found beneficial effects, covering more than 340 different diseases.

It also shares many beneficial effects with many bioflavonoids, such as reducing the onset of osteoporosis and can provide more effective Protection from other well-known antioxidants, such as vitamins E and C.

Anti-aging effect.

Studies in laboratory mice have found an increase in survival and a lower incidence of several diseases and conditions related to aging, but the results are contradictory.

The amount of fermentation time a wine goes through in contact with grape skins is an important determinant of its antioxidant content.

Grapes grown in humid environments tend to have more antioxidants than grapes grown in more arid environments. The theory behind this phenomenon is that grapes grown in humid environments produce more antioxidants to fight harmful fungi.
