Pterostilbene

同義語： Pterostilbene, 3,5-Dimethoxy-4′-hydroxy-trans-stilbene, trans-Pterostilbene, 4-[(E)-2-(3,5-Dimethoxyphenyl)ethenyl]phenol

Pterostilbene has moved from a research curiosity to a staple in the premium supplement aisle. Often called the ‘better resveratrol’ by formulators, it is attracting attention for its improved oral bioavailability and metabolic stability. Brands are incorporating it into anti-aging, cognitive support, and metabolic health products, where it competes directly with resveratrol but at lower doses.

Chemically, pterostilbene is a stilbenoid natural product, structurally related to resveratrol but with two methoxy groups replacing hydroxyl groups. It occurs naturally in small amounts in blueberries, grapes, and Pterocarpus marsupium, though commercial quantities are produced via synthetic routes to ensure purity and supply consistency. The compound’s lipophilic nature allows it to cross cell membranes more readily than its hydroxylated cousin.

LyvBio supplies pterostilbene with a minimum assay of 98% by HPLC, verified by an independent third-party laboratory. Each batch is tested for residual solvents, heavy metals, and microbial contamination to meet pharmaceutical and nutraceutical standards. Our material is manufactured under cGMP conditions and comes with a complete documentation package for regulatory submissions.

製品の概要と成分

Pterostilbene is a single, well-defined chemical entity, not a botanical extract. It is produced through a multi-step synthesis that yields a high-purity crystalline solid. The compound is characterized by its trans configuration, which is the biologically active form. We control the synthesis to minimize cis-isomer content, typically below 0.5%.

The material is stable under normal storage conditions. It should be kept in a cool, dry place away from direct sunlight and oxidizing agents. Our standard packaging includes an aluminum foil bag inside a fiber drum to protect against moisture and light.
