How does trans-resveratrol differ from other forms, and why does this matter when choosing a supplement? — Resveratrol VEGE, 60 Capsules – OstroVit

Resveratrol exists in two main forms - trans- and cis-. Trans-resveratrol is considered the most studied form of this polyphenol: it is the one most often referenced in scientific publications and used as a benchmark when assessing the composition of antioxidant supplements.

The trans-resveratrol in OstroVit Resveratrol VEGE is obtained from a standardised extract of Japanese knotweed root. Standardisation means that the content of the active form in the raw material is controlled, which allows the product to have a predictable composition from batch to batch, unlike non-standardised plant powders, where the polyphenol concentration can vary considerably.

When choosing an antioxidant supplement containing resveratrol, it is worth paying attention to which form is used and whether the extract is standardised - this information is usually stated on the label or in the composition description. Japanese knotweed is one of the most common plant sources of resveratrol in supplements, which makes it a standard raw material for such products.
