Description
Zinc Citrate Powder is a highly absorbable organic zinc salt, supplied as a white, fine powder. Zinc is an essential trace mineral for immune function, skin health, wound healing and normal growth, and binding it to citric acid improves both its solubility and its tolerance in the digestive tract compared with inorganic zinc forms. The powder blends easily into capsules, tablets and drink mixes, and its mild, neutral character suits fortification of foods and beverages without affecting flavor. Produced to USP-grade specifications with tight controls on heavy metals and microbiology, it offers a reliable, well-tolerated zinc source with stable quality for supplement and food manufacturers worldwide. Its white color and bland taste allow high fortification levels without visible or sensory changes to the final product. Produced to USP-grade specifications with tight controls on heavy metals and microbiology, it blends cleanly into powder and capsule systems. Its organic citrate form also avoids the metallic aftertaste of inorganic zinc salts. In practice it is dosed into lozenges, capsules and drink powders at milligram levels, where its neutral taste keeps small doses invisible in the formula. It also suits children's formats where gastric tolerance matters. Consistent batch-to-batch quality is maintained through defined raw-material sourcing and in-process control, protecting formula stability for industrial buyers. How Zinc Citrate works: zinc bound to citric acid forms a salt that dissolves readily and releases zinc in a form the body absorbs efficiently, without the metallic taste and stomach upset associated with some inorganic zinc sources. Zinc is essential for immune cell function, skin renewal, wound healing and normal growth, and the citrate form has become the preferred choice for daily immune-support products. Practical guidance: dose it into immune capsules, lozenges and effervescent tablets at milligram levels; fortify cereals, dairy and nutrition bars without changing flavor; build children's zinc products where gastric tolerance matters; and combine it with vitamin C and D in immune blends. Quality assurance: produced under USP specifications with zinc content, heavy metals and microbiology tested per batch and documented. Packed in 25 kg bags with a two-year shelf life. For immune and beauty product lines, zinc citrate delivers efficacy with tolerance - the combination that keeps customers taking the product daily. Specification highlights: it is packed in 25kg/bag with a minimum order quantity of 1000kg. Certificates of analysis accompany every shipment, and sample supply, specification customization and flexible payment terms are available for qualified buyers, supported by the standardized seven-step service process from inquiry to after-sales support. Documented quality from batch to batch: every production lot is verified against the full specification - identity, purity, heavy metals and microbiology - before release, and the resulting certificates and batch records travel with each shipment to support qualification and audit. Raw materials are sourced to defined standards, storage follows the conditions stated in the specification, and the product ships in its original, intact packaging. Shelf life and storage requirements are clearly documented, so purchasing, warehouse and quality teams all work from the same reference. This repeatable quality system is what makes the grade dependable for multi-year supply agreements.
Applications
It is used in immune-support supplements, multivitamins and zinc capsules, as well as effervescent tablets and drink mixes for cold-season wellness. Skincare-from-within formulas use it for skin clarity and healing support. Food manufacturers fortify cereals, nutrition bars and dairy with zinc citrate for a taste-neutral mineral boost, and oral care products use it for its role in oral health.
Advantages
The citrate form combines high absorption with excellent gastric tolerance, so brands can offer effective zinc doses without the metallic taste or nausea associated with some inorganic zinc salts. Its neutral flavor and fine powder form fit capsules, drinks and food fortification equally well. USP-grade purity, strict heavy-metal controls and reliable supply make it a safe, simple choice for immune and beauty product lines.
