To understand how Revitaa pro aids in weight loss, it is necessary to go through its formula first. This entire idea of Revitaa pro is based on an ancient Japanese remedy that uses a plant called ‘knotweed’. The scientific name of this plant is polygonum cuspidatum and its root has been used for thousands of years against treating various medical conditions. Robert Miller, the creator of this product was introduced to this root through a medical expert Dr. Nakamura. Resveratrol is the chief ingredient in Revitaa Pro pills. Almost all of the benefits associated with this formula are because of resveratrol. Japanese knotweed is not the only source to get this antioxidant as it is also found in grapes and some berries. However, knotweed has the highest and purest resveratrol to offer that is linked with faster and safer benefits compared to resveratrol obtained from other sources.
