Swanson Robuvit French Oak Wood Extract 200 mg 30 Veg Caps.

From Horphag Research, makers of world-famous Pycnogenol(R), comes a unique dietary supplement unlike anything on the market today. Robuvit(R) French Oak Wood Extract contains a unique profile of polyphenols that show tremendous promise for promoting physical and mental wellness. The secret appears to lie in a unique class of polyphenolic tannins known as roburins, found only in oak trees. Among their numerous beneficial properties, research suggests that roburins can help enhance basic cellular functions to combat the aging process, increase energy and fend off fatigue. Roburins belong to a class of tannins known as ellagitannins, which are hydrolysable derivatives of ellagic acid, a powerful antioxidant also found in pomegranates and raspberries. What makes roburins unique is that they exhibit low bioavailability until they are metabolized by bacteria in the intestinal tract to produce bioactive molecules called urolithins, which are then taken up into blood plasma. Once in the plasma, urolithins are circulated throughout the body to provide broad- spectrum protection against oxidative stress, a primary factor in the onset of fatigue. Above and beyond their antioxidant potential, roburins also appear to fight fatigue at the cellular level by up-regulating genes involved in ribosomal biogenesis, the renewal of cellular structures known as ribosomes, which are responsible for protein production in all living cells. By supporting ribosomal function, roburins can have a broad range of healthful effects throughout the body, from energy production to enzymatic activity and cellular renewal. Until recently, little was known about the potential health benefits of roburins, primarily because there was no good source available for study. Roburins are only found in trees of the oak genus Quercus, limiting dietary sources to the trace amounts found in wines and liquors aged in oaken casks. To overcome this limitation, Horphag Research, the makers of Pycnogenol(R), applied their decades of expertise in extraction technology to develop Robuvit, a GMO-free French oak wood extract standardized to an impressive 40% roburin content.
