Zinc Picolinate Bulk Powder is a high‑purity, chelated zinc supplement, delivering approximately 20% – 22% elemental zinc per dose in a versatile powder form. Designed for dietary supplements, functional foods, and pharmaceutical formulations, this product offers superior bioavailability compared to inorganic zinc salts (e.g., zinc sulfate or zinc oxide), as the picolinate ligand facilitates efficient intestinal absorption. Each batch provides precise, standardized zinc content with excellent stability, compatibility with other nutrients (such as vitamin C, copper, and magnesium), and a neutral taste suitable for tablets, capsules, sachets, and powder blends. Manufactured under strict GMP, Halal, Kosher, and ISO 9001 standards, our Zinc Picolinate Bulk Powder is supplied with full COA, MSDS, stability data, and comprehensive heavy metal/microbiological test reports to support your regulatory filings and global market access. Customizable particle sizes, flexible MOQs (from 1kg lab samples to tonne‑scale bulk), and tailored packaging options are available to meet your specific production requirements.
