Japanese Knotweed 2 fl oz
Providing a more concentrated source of resveratrol, Japanese knotweed is preferred over grape skins by many dietary supplement manufacturers. Unlike grapes, Japanese knotweed can be grown year round, allowing manufacturers to have a consistent source of resveratrol for their pills. Knotweed contains the potent antioxidant resveratrol, which can help to lower cholesterol, regulate blood pressure and the digestive system.* Offered in a 2 fl oz liquid tincture.
