Polygonum Cuspidatum Root Extract Powder Ingredient

Polygonum cuspidatum root extract powder is a botanical ingredient supplied for nutraceutical and dietary supplement development. The product images show a fine, slightly granular powder in a uniform tan-brown color, with soft clumps and a dry, matte surface. Dried, sliced root pieces appear alongside the powder, which points to a root-derived botanical source. As a botanical extract, it is commonly sourced by manufacturers developing capsules, tablets, powder blends, and custom premixes. Supplement brands, contract manufacturers, and ingredient distributors may consider it when building botanical formulations or comparing ingredient options for private label and OEM programs. Specifications such as extract ratio, standardization, and packaging details are not shown in the images, so buyers should request current technical documentation, a specification sheet, and a certificate of analysis before procurement or formulation planning.
