Product Description
curcumin is a natural polyphenol extracted from turmeric rhizomes and widely used as a standardized botanical ingredient in nutraceutical, food, and cosmetic formulations. It is valued for its high curcuminoid content, antioxidant properties, and suitability for supplement brands requiring consistent botanical extract quality.
High Purity Curcumin is a refined turmeric-derived ingredient supplied in standardized grades for professional formulation applications. Buyers typically evaluate curcumin based on curcuminoid percentage, extraction method, bioavailability requirements, analytical testing, and compatibility with the intended dosage form.
Curcumin is the principal bioactive curcuminoid found in turmeric (Curcuma longa) root. It is a natural polyphenolic compound commonly extracted and purified from turmeric oleoresin or turmeric rhizomes for use in dietary supplements, functional foods, beverages, and cosmetic formulations.
Commercial curcumin ingredients are usually standardized by total curcuminoids, with common specifications including 95% curcuminoids. Higher-performance formulations may combine curcumin with technologies designed to improve dispersion, stability, or absorption characteristics.
