Zinc Citrate 31%
Nanjing Gemsen
CAS 546-46-3
Introduction：
Product name | Zinc Citrate |
Synonyms | Chelated Zinc |
Appearance | White Powder |
Purity | Zinc 31% |
Sample | Available |
Chelation technology represents one advanced pathway for mineral delivery, Zinc Citrate establishes its distinct superiority through an alternative mechanism of high bioavailability. This organic zinc salt is characterized by its exceptional water solubility, which facilitates rapid dissolution and efficient absorption in the intestinal tract. Unlike minimally absorbed compounds such as zinc oxide, citrate offers a readily available form of elemental zinc that functions systemically as a vital enzymatic cofactor. Its fundamental role extends beyond basic supplementation to the precise regulation of key metabolic, immune, and physiological processes throughout the body.

Function and Application:
1. As a highly bioavailable oral zinc source, Zinc Citrate ensures efficient systemic replenishment for addressing deficiencies linked to impaired immune function, slowed growth in children, and metabolic dysregulation, distinguishing it categorically from the topical, localized action of zinc oxide.
2. Zinc Citrate exerts a broad immunomodulatory effect by serving as an essential cofactor for enzymes crucial to immune cell development and activity, thereby enhancing the body's foundational defense mechanisms against pathogens.
3. Emerging evidence underscores its specific role in supporting skeletal integrity; Zinc Citrate participates in osteometabolic regulation, aiding bone formation and mineralization, which positions it as a critical component in geriatric nutritional formulations aimed at maintaining bone density.
4. Within oral healthcare applications, it delivers dual-action benefits: systemic nutritional support through oral supplementation combined with localized antibacterial activity in dental hygiene products (e.g., toothpaste, mouthwash), creating a comprehensive "internal-external" strategy for promoting periodontal and mucosal health.
5. By contributing to the synthesis of digestive enzymes and fostering a balanced intestinal environment, Zinc Citrate aids in nutrient assimilation and supports gastrointestinal well-being, making it suitable for functional food formulations designed for individuals with mild digestive susceptibilities.
