Japanese Knotweed Extract

Resveratrol (also -3,4,5-trihydroxystilben) is a natural polyphenol with antioxidant properties and a derivative of stilbene.
Our resveratrol is made from Japanese knotweed (Polygonum cuspidatum, also known as Fallopia japonica or Reynoutria japonica), which is native to China, Japan and Korea. For this purpose, the active ingredient is extracted from the roots of the plant. By continuously concentrating during this process, different proportions of resveratrol can be obtained in the end product.
We mainly offer the following variants:

Japanese Knotweed Extract, min. 60% trans resveratrol, conventional quality
Japanese Knotweed Extract, min. 98% trans resveratrol, conventional quality
