CranVerry+ is immediately associated with the cranberry, especially since this dietary supplement is noticeably named after this tart fruit with a deep red hue. You get the entire berry as an extract in each serving: 500 mg to be exact.
The plus sign after CranVerry refers to three additional ingredients. Along with cranberry extract, the formulation features beta-glucanase, mangosteen and giant knotweed, which has been used for centuries in traditional Asian medicine. In Japan, knotweed is called itadori,1 roughly translated as pain puller.
Knotweed’s scientific names include Polygonum cuspidatum and Reynoutria japonica, depending on official usage. This explains the different scientific names for giant knotweed on U.S. and Canadian product labels of CranVerry+.
The extract of giant knotweed in CranVerry+ provides a naturally rich, plant-based source of the polyphenol resveratrol. Each serving delivers 25 mg of biologically active trans-resveratrol,2 another example of how AIM selects the most effective ingredients. In this case, AIM gets to the heart of the giant knotweed root’s therapeutic potential.
A Natural Phytoalexin
In response to pathogen attack, plants such as the giant knotweed produce antimicrobial substances called phytoalexins. Resveratrol is a natural phytoalexin.3
Just as phytoalexins effectively work to protect the knotweed, resveratrol works to protect the body, making it a natural addition to a dietary supplement that supports a healthy urinary tract.4
Notably, resveratrol delivers the benefit of antioxidant activity, contributing to a reduction in oxidative stress by neutralizing free radicals and their potential damage to the body. Pairing well with antioxidant-rich cranberries and mangosteen, resveratrol is a fine addition to the ingredients in CranVerry+.
