Pterostilbene

Pterostilbene is a naturally occurring stilbenoid, the dimethylated analogue of resveratrol, found in small amounts in blueberries, grapes and the heartwood of Pterocarpus species. Nustras supplies it as an off-white to white powder, produced by chemical synthesis to high purity, for use as a polyphenol ingredient in supplements and functional foods.

It is formulated into capsules, tablets, softgels and powder blends, often alongside resveratrol and other polyphenols, and is used in functional beverages, premix systems and cosmetic formulations. Its two methoxy groups give it greater lipid solubility than resveratrol, a property formulators take into account when choosing carriers and delivery formats.

The material is an off-white or white powder. CAS number 537-42-8. Purity is assayed by HPLC and standardised to specification, with identity confirmed by HPLC retention and spectroscopic comparison to a reference standard. Residual solvents, heavy-metal and microbial limits are supplied to specification and confirmed on each lot’s certificate of analysis.

Nustras supplies pterostilbene in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Pterostilbene is accepted as a supplement ingredient in several major markets; buyers confirm its regulatory status, permitted level and claim for their application.
