The Russian Rejuvenating Formula of Dr. Stephen Langer delivers Dihydroquercetin (DHQ), also known as Taxifolin, for energy stimulation of the whole body with antioxidant power. This supplement exceeds the benefits of quercetin thanks to the strongly soluble and bioavailable form of DHQ (regular quercetin is neither soluble, nor bioavailable). In fact, researchers have found out that in case of moderate exhaustion, 50 mg of DHQ effectively restore the normal state and recover the body. With the Russian Rejuvenating Formula you get 50 mg of FlavitPURE ™ Dihydroquercetin from the Siberian Larch Tree. More information about DHQ: The Russian Rejuvenating Formula by Swanson uses DHQ, developed by the Russian scientist Dr. Anatoliy Gavrilov from the Russian Academy of Sciences. Dr. Gavrilov uses an innovative technology to extract a super pure, natural form of the powerful antioxidant DHQ, using only purified water and small quantities of ethanol. In 2005 the scientist was awarded the Russian Innovation Award and FlavitPURE DHQ became the golden standard for Dihydroquercetin. DHQ was first identified as a powerful antioxidant in 1940. In 1958 the journal of the American Pharmaceutical Association published a survey about its safety. In medical literature the benefits of DHQ are well-known. In Russia it is classified as an antioxidant, neuroprotective, regenerating and detoxifying substance.
