Since it was first isolated nearly 80 years ago, vitamin C has been deemed essential for life and for maintaining optimal health and well-being. Its potent antioxidant properties and critical role in facilitating essential biochemical reactions throughout the body have made vitamin C the most widely consumed nutritional supplement.

Because humans do not manufacture vitamin C internally, it must be obtained through dietary sources or supplements. Few people realize, however, that vitamin C is a water soluble nutrient that is quickly oxidized and excreted by the body, which limits its efficacy. Until now, those seeking to capture vitamin C's optimal health benefits have had no choice but to consume it several times throughout the day.

Fortunately, a flavonoid antioxidant known as dihydroquercetin functions as a vitamin C "supercharger." Studies demonstrate that dihydroquercetin acts to inhibit the oxidation of vitamin C, thereby helping to maintain its concentration and to recycle vitamin C throughout the body. This synergistic relationship between dihydroquercetin and vitamin C greatly enhances the efficacy of both molecules in the body's organs and tissues.

Vitamin C with Dihydroquercetin was formulated for those seeking to obtain optimal efficacy and antioxidant protection from their vitamin C supplement.

Dihydroquercetin-3-rhamnoside (D-3-R) is a flavonoid and potent water soluble antioxidant that is synergistic with Vitamin C. Unlike many flavonoids, D-30R is very bioavailable. Professor Szent-Gyorgyi, the recipient of the Nobel Prize for Vitamin C, categorized flavonoids such as D-3-R as "vitamin P," making Vitamin C more biologically active and available.
