Itadori Extract (Polygonum cuspidatum)

Itadori, or Japanese Knotweed, contains resveratrol and related compounds that activate sirtuins—proteins involved in cellular repair and healthy aging processes. This can promote mitochondrial resilience over time. For product comparison, Itadori Extract (Polygonum cuspidatum) should be checked by exact form, plant part or compound type, standardization, amount per serving, and whether it is listed as an active ingredient, other ingredient, or part of a blend.
