Buy Resveratrol – Extracts From Japanese Knotweed & Red Grapes

Resveratrol is a secondary plant compound from the group of polyphenols, more specifically the stilbenes. It occurs naturally in the skins of red grapes, in red wine and above all in Japanese knotweed (Polygonum cuspidatum), and is one of the most intensively researched plant compounds. In this category you'll find resveratrol products from Scheunengut – standardised to a defined content, vegan and lab-tested.

Origin & Extraction

The most important raw material source for high-dose supplements is Japanese knotweed, whose root is especially rich in resveratrol. The compound can also be obtained from red grapes, though in a considerably lower concentration. Extraction is carried out gently, after which the raw material is standardised to its resveratrol content.

Standardisation & Form

What matters is the standardised resveratrol content – high-quality extracts often show a share of 98% trans-resveratrol. Resveratrol is mostly available as capsules or powder. It is commonly combined with piperine from black pepper as well as with other polyphenols such as quercetin or OPC.
