About this supplement

Trans-resveratrol is a specific stereoisomer of resveratrol, a naturally occurring polyphenolic stilbene compound. As a standardized extract, it contains a consistent, quantified percentage of trans-resveratrol, typically ranging from 50% to 98% purity. This form is the biologically active isomer known for its potent antioxidant, anti-inflammatory, and sirtuin-activating properties. It is extensively researched for its potential effects on longevity pathways, cardiovascular health, neuroprotection, and metabolic regulation. The 'trans-' configuration is more stable and bioactive than its cis-isomer counterpart, especially in standardized extracts that ensure reliable potency for dietary supplement and research applications.

Technical details â–¼

Chemical ID (CAS)

501-36-0

Formula

C14H12O3

Physical properties

White to pale yellow crystalline powder. Poor solubility in water; soluble in organic solvents like ethanol, DMSO, and lipids. Melting point approximately 256-258°C. Sensitive to light, heat, and pH changes, which can cause isomerization to the cis-form.

How it’s made

Typically extracted from Polygonum cuspidatum (Japanese knotweed) root, grape skins, or red wine byproducts using solvent extraction (e.g., ethanol). The extract is then purified and standardized via chromatography or crystallization to achieve a high percentage of trans-resveratrol. Some commercial production uses biotechnological methods (fermentation, plant cell culture) or chemical synthesis followed by purification.
