Formulation
Resveratrol 98% in Finished Products
The powder's solubility, taste and physical characteristics are practical considerations during product development.
Powder & Solubility
The ingredient is insoluble in water and soluble in ethanol. Dry formulations can work directly with the powder format; water-based products require a separate approach to dispersion.
Source Information
The product uses glucose (yeast) as the listed starting material, with corn identified as the source. Ethanol is listed as the solvent used.
Storage
Keep Cool, Dry & Protected
