Product Introduction<\/h2>\n
Resveratrol Powder is a concentrated botanical extract derived from the roots and rhizomes of Polygonum cuspidatum<\/em>. Unlike physically ground crude material, this extract isolates and enriches trans-resveratrol via controlled low-temperature solvent extraction and optional recrystallization, delivering a standardized raw material for nutraceutical manufacturers requiring batch-to-batch consistency on the trans-isomer marker.<\/div>\n
