From Horphag Research, the world-renowned manufacturer of Pycnogenol®, comes a unique dietary supplement unlike any other currently available on the market. Robuvit® French Oak Wood Extract contains a unique profile of polyphenols that show great promise in promoting physical and mental well-being.

The secret likely lies in a unique group of polyphenolic tannins called roburins, found only in oak trees. Studies show that roburins can help improve basic cell functions, counteract the aging process, increase energy and make the body resistant to fatigue.

Roburins belong to a group of tannins called ellagitannins, which are derivatives of hydrolyzed ellagic acid, a powerful antioxidant also found in pomegranates and raspberries. What makes roburins unique is that they have low bioavailability until they are processed by bacteria in the gut to form bioactive molecules called urolithins, which are then absorbed into the blood. Urolithins circulate throughout the body, providing protection against oxidative stress, a major contributor to fatigue.

In addition, roburins have been shown to combat fatigue at the cellular level by regulating genes responsible for the biogenesis of ribosomes, the structures responsible for protein production in all cells. By supporting ribosome function, roburins may have a wide range of beneficial effects throughout the body, from energy production to enzymatic activity to cellular renewal.

Until recently, little was known about the potential health benefits of roburins. This was primarily due to the lack of a good source for research. Roburins are found only in trees of the Quercus oak genus, which limits dietary sources to trace amounts found in wines and spirits aged in oak barrels. To overcome this, Horphag Research, the manufacturer of Pycnogenol®, used its decades of experience in extraction technology to create Robuvit, a non-GMO French oak extract standardized at an impressive 40% roburin content. This product has proven effective in human clinical trials, improving exercise performance and recovery from exercise.
