What Is Resveratrol Powder?
Resveratrol Powder is a polyphenol ingredient commonly supplied as trans-resveratrol for dietary supplement manufacturing.
Resveratrol em pó is commonly sourced as trans-resveratrol, the trans-isomer form of resveratrol. It can be derived from Polygonum cuspidatum root, grape skin or fermentation-based production routes depending on the selected grade and label strategy. In B2B supplement sourcing, buyers usually evaluate Resveratrol Powder by CAS number, chemical identity, trans-isomer percentage, HPLC purity, botanical or fermentation source, color, particle size, bulk density, residual solvents, Emodin level, heavy metals, microbiology, solubility, flowability, documentation, packaging and destination market label requirements.
Trans-Isomer Focus
Trans-resveratrol identity and trans/cis isomer control should be confirmed by specification and batch documentation before supplier approval.
Análise da pureza e da composição
High-purity grades are commonly reviewed by HPLC assay, related substances, color, loss on drying and residual solvent profile.
Foco no abastecimento de suplementos
Gensei supports supplement brands, OEM factories and contract manufacturers with bulk resveratrol sourcing and technical documentation.
