Beyond Quercetin: Supercharged DHQ

Swanson Health Products introduces a supplement that is beyond quercetin. Dr. Stephen Langer’s Russian Rejuvenator with supercharged FlavitPURE™ DHQ is an energy-promoting antioxidant supplement for good health and stamina.

Fargo, ND (VOCUS) October 19, 2010—DHQ (Dihydroquercetin) is the ultimate antioxidant flavanoid—more powerful and bioavailaible than quercetin and proven to work inside cells. Dr. Stephen Langer’s Russian Rejuvenator features FlavitPURE™ DHQ from Russia, the purest all-natural DHQ extracted from Siberian and Dahurian Larch trees. Swanson Health Products now offers Dr. Stephen Langer’s Russian Rejuvenator DHQ plus Vitamin C in the Swanson Ultra line.

Dr. Langer’s Russian Rejuvenator’s exclusive DHQ has an incredibly high ORAC rating (28,000/gram) and provides your total recommended daily intake of ORAC units. In addition to the DHQ, Dr. Langer included 70 mg of vitamin C in each capsule. Vitamin C supercharges DHQ, optimizing its absorption and boosting its activity inside cells. 

“As a physician, I’ve used quercetin as an antioxidant—specifically for vascular health,” states Dr. Langer. “DHQ, the direct precursor in the formation of quercetin, is among the most powerful natural antioxidants and holds particular benefits for cardiovascular health, ocular (eye) health, and neurological health as well as an aid for human performance.”
