Interesting Fact
Itadori Extract: A Source of Natural Resveratrol
Itadori Extract is derived from the Japanese Knotweed (Polygonum cuspidatum), a plant naturally rich in resveratrol—the same beneficial compound found in red grapes and wine. Unlike many other plant extracts, Itadori is a particularly concentrated botanical source of resveratrol, making it a popular alternative for those seeking this polyphenol from a non-grape origin.
