Protykin

Protykin is a standardized natural extract derived from *Polygonum cuspidatum* (Japanese knotweed), developed by InterHealth Nutraceuticals (now part of Lonza). It is characterized by a high concentration of bioactive compounds, specifically standardized to contain 20% trans-resveratrol and 10% emodin. As a dietary supplement ingredient, it is primarily utilized for its antioxidant and phytoestrogenic properties. Research indicates its potential in providing cardioprotection through free radical scavenging activity during ischemic injury. Additionally, it is marketed for managing menopausal symptoms, such as hot flashes and mood swings, by helping to maintain normal estrogen activity and supporting healthy bone density. It is typically used as an ingredient in various formulations for cardiovascular health and menopausal support rather than as an approved pharmaceutical drug.
