Natural Pterostilbene

At SupplySide East, Sabinsa (East Windsor, NJ) promoted Silbinol and pTeroWhite, the company’s proprietary pterostilbene ingredients, for nutritional and cosmetic applications, respectively. The pterostilbene is extracted from the dried heartwood of Pterocarpus marsupium.

Pterostilbene is a structural analog of resveratrol and has shown to be more stable and more effective in inhibiting pro-inflammatory enzymes in vivo than resveratrol, the company says. Its benefits over resveratrol include: better absorption/biologically active, more powerful antifungal properties, better inhibitor activity of DNA synthesis in the human adenocarcinoma HT-29 cell line, and better inhibition of cell membranes against lipid peroxidation.
