Pterostilbene 98% (StilbElite™) supplier specification
Nutrition BioTech is a bulk pterostilbene ingredient supplier and manufacturer, supplying pterostilbene (CAS 537-42-8) at 98% minimum by HPLC as StilbElite™, produced by organic synthesis, for B2B nutraceutical and cosmetic formulation.
Pterostilbene is the dimethylated stilbene analogue of resveratrol, and like resveratrol it is practically insoluble in water, so particle size, solubilisation format and blend uniformity matter alongside the 98% assay. Every lot ships with a Certificate of Analysis stating identity, HPLC assay and the assay basis.
